The manufacturer shall demonstrate compliance in accordance with paragraph ANNEX 1.3.5.2.7. ANEX 1 Test conditions and procedures 1. Compliance tests for fuel system integrity 1.1. Post-crash compressed hydrogen storage system leak test The crash tests used to evaluate post-crash hydrogen leakage are those already applied in the jurisdictions of each contracting party. Prior to conducting the crash test, instrumentation is installed in the hydrogen storage system to perform the required pressure and temperature measurements if the standard vehicle does not already have instrumentation with the required accuracy. The storage system is then purged, if necessary, following manufacturer directions to remove impurities from the container before filling the storage system with compressed hydrogen or helium gas. Since the storage system pressure varies with temperature, the targeted fill pressure is a function of the temperature. The target pressure shall be determined from the following equation: Ptarget = NWP x (273 + To) / 288 where NWP is the nominal working pressure (MPa), To is the ambient temperature to which the storage system is expected to settle, and Ptarget is the targeted fill pressure after the temperature settles. The container is filled to a minimum of 95 per cent of the targeted fill pressure and allowed to settle (stabilize) prior to conducting the crash test. 29 قرار مجلس الوزراء لسنة2021 بشأن النظام الإماراتي للمركبات الهيدروجينية The main stop valve and shut-off valves for hydrogen gas, located in the downstream hydrogen gas piping, are kept open immediately prior to the impact. 1.1.1. Post-crash leak test - compressed hydrogen storage system filled with compressed hydrogen The hydrogen gas pressure, P0 (MPa), and temperature, T0 (°C), is measured immediately before the impact and then at a time interval, Δt (min), after the impact. The time interval, Δt, starts when the vehicle comes to rest after the impact and continues for at least 60 minutes. The time interval, Δt, is increased if necessary in order to accommodate measurement accuracy for a storage system with a large volume operating up to 70MPa; in that case, Δt can be calculated from the following equation: Δt = VCHSS x NWP /1000 x ((-0.027 x NWP +4) x Rs – 0.21) -1.7 x Rs where Rs = Ps / NWP, Ps is the pressure range of the pressure sensor (MPa), NWP is the Nominal Working Pressure (MPa), VCHSS is the volume of the compressed hydrogen storage system (L), and Δt is the time interval (min). If the calculated value of Δt is less than 60 minutes, Δt is set to 60 minutes. The initial mass of hydrogen in the storage system can be calculated as follows: Po’ = Po x 288 / (273 + T0) ρo’ = –0.0027 x (P0’(2 + 0.75 x P0’ + 0.5789 Mo = ρo’ x VCHSS Correspondingly, the final mass of hydrogen in the storage system, Mf, at the end of the time interval, Δt, can be calculated as follows: Pf’ = Pf x 288 / (273 + Tf) ρf’ = –0.0027 x (Pf’(2 + 0.75 x Pf’ + 0.5789 Mf = ρf’ x VCHSS where Pf is the measured final pressure (MPa) at the end of the time interval, and Tf is the measured final temperature )°C(. The average hydrogen flow rate over the time interval (that shall be less than the criteria in 5.2.2.1.) is therefore VH2 = (Mf-Mo) / Δt x 22.41 / 2.016 x (Ptarget /Po) where VH2 is the average volumetric flow rate (NL/min) over the time interval and the term (Ptarget /Po) is used to compensate for differences between the measured initial pressure, Po, and the targeted fill pressure Ptarget. 1.1.2. Post-crash leak test - Compressed hydrogen storage system filled with compressed helium The helium gas pressure, P0 (MPa), and temperature T0 )°C(, are measured immediately before the impact and then at a predetermined time interval after the impact. The time interval, Δt, starts when the vehicle comes to rest after the impact and continues for at least 60 minutes. The time interval, Δt, shall be increased if necessary in order to accommodate measurement accuracy for a storage system with a large volume operating up to 70MPa; in that case, Δt can be calculated from the following equation: 30 قرار مجلس الوزراء لسنة2021 بشأن النظام الإماراتي للمركبات الهيدروجينية Δt = VCHSS x NWP /1000 x ((-0.028 x NWP +5.5) x Rs – 0.3) – 2.6 x Rs where Rs = Ps / NWP, Ps is the pressure range of the pressure sensor (MPa), NWP is the Nominal Working Pressure (MPa), VCHSS is the volume of the compressed storage system (L), and Δt is the time interval (min). If the value of Δt is less than 60 minutes, Δt is set to 60 minutes. The initial mass of hydrogen in the storage system is calculated as follows: Po’ = Po x 288 / (273 + T0) ρo’ = –0.0043 x (P0’(2 + 1.53 x P0’ + 1.49 Mo = ρo’ x VCHSS The final mass of hydrogen in the storage system at the end of the time interval, Δt, is calculated as follows: Pf’ = Pf x 288 / (273 + Tf) ρf’ = –0.0043 x (Pf’(2 + 1.53 x Pf’ + 1.49 Mf = ρf’ x VCHSS where Pf is the measured final pressure (MPa) at the end of the time interval, and Tf is the measured final temperature (°C). The average helium flow rate over the time interval is therefore VHe = (Mf-Mo) / Δt x 22.41 / 4.003 x (Po/ Ptarget) where VHe is the average volumetric flow rate (NL/min) over the time interval and the term Po/ Ptarget is used to compensate for differences between the measured initial pressure (Po) and the targeted fill pressure (Ptarget). Conversion of the average volumetric flow of helium to the average hydrogen flow is done with the following expression: VH2 = VHe / 0.75 where VH2 is the corresponding average volumetric flow of hydrogen (that shall be less than the criteria in 5.2.2.1. to pass). 1.2. Post-crash concentration test for enclosed spaces The measurements are recorded in the crash test that evaluates potential hydrogen (or helium) leakage ( 1.1. test procedure). Sensors are selected to measure either the build-up of the hydrogen or helium gas or the reduction in oxygen (due to displacement of air by leaking hydrogen/helium). Sensors are calibrated to traceable references to ensure an accuracy of ±5 per cent at the targeted criteria of 4 per cent hydrogen or 3 per cent helium by volume in air, and a full scale measurement capability of at least 25 per cent above the target criteria. The sensor shall be capable of a 90 per cent response to a full scale change in concentration within 10 seconds. Prior to the crash impact, the sensors are located in the passenger, luggage, and cargo compartments of the vehicle as follows: (a) At a distance within 250 mm of the headliner above the driver’s seat or near the top centre the passenger compartment; 31 قرار مجلس الوزراء لسنة2021 بشأن النظام الإماراتي للمركبات الهيدروجينية (b) At a distance within 250 mm of the floor in front of the rear (or rear most) seat in the passenger compartment; (c) At a distance within 100 mm of the top of luggage and cargo compartments within the vehicle that are not directly affected by the particular crash impact to be conducted. The sensors are securely mounted on the vehicle structure or seats and protected for the planned crash test from debris, air bag exhaust gas and projectiles. The measurements following the crash are recorded by instruments located within the vehicle or by remote transmission. The vehicle may be located either outdoors in an area protected from the wind and possible solar effects or indoors in a space that is large enough or ventilated to prevent the build-up of hydrogen to more than 10 per cent of the targeted criteria in the passenger, luggage, and cargo compartments. Post-crash data collection in enclosed spaces commences when the vehicle comes to a rest. Data from the sensors are collected at least every 5 seconds and continue for a period of 60 minutes after the test. A first-order lag (time constant) up to a maximum of 5 seconds may be applied to the measurements to provide "smoothing" and filter the effects of spurious data points. The filtered readings from each sensor shall be below the targeted criteria of 3±1.0 per cent for hydrogen and 2.25 ± 0.75 per cent for helium at all times throughout the 60 minutes post-crash test period. 1.3. Compliance test for single failure conditions Either test procedure of 1.3.1. or 1.3.2. shall be executed: 1.3.1. Test procedure for vehicle equipped with hydrogen gas leakage detectors 1.3.1.1.Test condition 1.3.1.1.1 Test vehicle: The propulsion system of the test vehicle is started, warmed up to its normal operating temperature, and left operating for the test duration. If the vehicle is not a fuel cell vehicle, it is warmed up and kept idling. If the test vehicle has a system to stop idling automatically, measures are taken so as to prevent the engine from stopping. 1.3.1.1.2. Test gas: Two mixtures of air and hydrogen gas: 2 ± 1.0 per cent concentration (or less) of hydrogen in the air to verify function of the warning, and 3±1.0 per cent concentration (or less) of hydrogen in the air to verify function of the shut-down. The proper concentrations are selected based on the recommendation (or the detector specification) by the manufacturer. 1.3.1.2. Test method 1.3.1.2.1.

Test procedure for integrity of enclosed spaces and detection systems. 1.3.2.1. Preparation: 1.3.2.1.1. The test is conducted without any influence of wind. 1.3.2.1.2. Special attention is paid to the test environment as during the test flammable mixtures of hydrogen and air may occur. 1.3.2.1.3. Prior to the test the vehicle is prepared to allow remotely controllable hydrogen releases from the hydrogen system. The number, location and flow capacity of the release points downstream of the main hydrogen shutoff valve are defined by the vehicle manufacturer taking worst case leakage scenarios into account. As a minimum, the total flow of all remotely controlled releases shall be adequate to trigger demonstration of the automatic "warning" and hydrogen shut-off functions. 1.3.2.1.4. For the purpose of the test, a hydrogen concentration detector is installed where hydrogen gas may accumulate most in the passenger compartment (e.g. near the headliner) when testing for compliance with 5.2.1.4.2. and hydrogen concentration detectors are installed in enclosed or semi enclosed volumes on the vehicle where hydrogen can accumulate from the simulated hydrogen releases when testing for compliance with 5.2.1.4.3. (see 1.3.2.1.3.). 1.3.2.2. Procedure: 1.3.2.2.1. Vehicle doors, windows and other covers are closed. 1.3.2.2.2. The propulsion system is started , allowed to warm up to its normal operating temperature and left operating at idle for the test duration. 1.3.2.2.3. A leak is simulated using the remote controllable function. 1.3.2.2.4. The hydrogen concentration is measured continuously until the concentration does not rise for 3 minutes. When testing for compliance with 5.2.1.4.3., the simulated leak is then increased using the remote controllable function until the main hydrogen shutoff valve is closed and the tell-tale warning signal is activated. The monitoring of the electric power to the shut-off valve or of the sound of the shut-off valve activation may be used to confirm the operation of the main shut-off valve of the hydrogen supply. 1.3.2.2.5. When testing for compliance with 5.2.1.4.2., the test is successfully completed if the hydrogen concentration in the passenger compartment does not exceed 1.0 per cent. When testing for compliance with 5.2.1.4.3., the test is successfully completed if the tell-tale warning and shut-off 33 قرار مجلس الوزراء لسنة2021 بشأن النظام الإماراتي للمركبات الهيدروجينية function are executed at (or below) the levels specified in 5.2.1.4.3.; otherwise, the test is failed and the system is not qualified for vehicle service. 1.4.

The measuring device is warmed up before use to its normal operating temperature. 1.4.3. The measuring section of the measuring device is placed on the centre line of the exhaust gas flow within 100 mm from the exhaust gas outlet external to the vehicle. 1.4.4. The exhaust hydrogen concentration is continuously measured during the following steps: (a) The power system is shut down; (b) Upon completion of the shut-down process, the power system is immediately started; (c) After a lapse of one minute, the power system is turned off and measurement continues until the power system shut-down procedure is completed. 1.4.5. The measurement device shall have a measurement response time of less than 300 milliseconds. 1.5. Compliance test for fuel line leakage 1.5.1. The power system of the test vehicle (e.g. fuel cell stack or engine) is warmed up and operating at its normal operating temperature with the operating pressure applied to fuel lines. 1.5.2. Hydrogen leakage is evaluated at accessible sections of the fuel lines from the high-pressure section to the fuel cell stack (or the engine), using a gas detector or leak detecting liquid, such as soap solution. 1.5.3. Hydrogen leak detection is performed primarily at joints 1.5.4. When a gas leak detector is used, detection is performed by operating the leak detector for at least 10 seconds at locations as close to fuel lines as possible. 1.5.5. When a leak detecting liquid is used, hydrogen gas leak detection is performed immediately after applying the liquid. In addition, visual checks are performed a few minutes after the application of liquid in order to check for bubbles caused by trace leaks. 1. Installation verification The system is visually inspected for compliance. 2. Test procedures for compressed hydrogen storage 2.1.

The rate of pressurization is less than or equal to 1.4 MPa/s for pressures higher than 150 per cent of the nominal working pressure. If the rate exceeds 0.35 MPa/s at pressures higher than 150 per cent NWP, then either the container is placed in series between the pressure source and the pressure measurement device, or the time at the pressure above a target burst pressure exceeds 5 seconds. The burst pressure of the container shall be recorded. 2.2.2. Pressure cycling test (hydraulic) The test is performed in accordance with the following procedure: (a) The container is filled with a non-corrosive fluid; (b) The container and fluid are stabilized at the specified temperature and relative humidity at the start of testing; the environment, fuelling fluid and container skin are maintained at the specified temperature for the duration of the testing.

Test procedures for performance durability (requirement of 5.1.2.) 2.3.1. Proof pressure test The system is pressurized smoothly and continually with a non-corrosive hydraulic fluid until the target test pressure level is reached and then held for the specified time. 2.3.2. Drop (impact) test (unpressurized) The storage container is drop tested at ambient temperature without internal pressurization or attached valves. The surface onto which the containers are dropped shall be a smooth, horizontal concrete pad or other flooring type with equivalent hardness. (a) The orientation of the container being dropped (per requirement of 5.1.2.2.) is determined as follows: One or more additional container(s) shall be dropped in each of the orientations described below. The drop orientations may be executed with a single container or as many as four containers may be used to accomplish the four drop orientations. (i) Dropped once from a horizontal position with the bottom 1.8 m above the surface onto which it is dropped; (ii) Dropped once onto the end of the container from a vertical position with the ported end upward with a potential energy of not less than 488 J, with the height of the lower end no greater than 1.8 m; (iii) Dropped once onto the end of the container from a vertical position with the ported end downward with a potential energy of not less than 488 J, with the height of the lower end no greater than 1.8 m. If the container is symmetrical (identical ported ends), this drop orientation is not required; 35 قرار مجلس الوزراء لسنة2021 بشأن النظام الإماراتي للمركبات الهيدروجينية (iv) Dropped once at a 45° angle from the vertical orientation with a ported end downward with its centre of gravity 1.8 m above the ground. However, if the bottom is closer to the ground than 0.6 m, the drop angle shall be changed to maintain a minimum height of 0.6 m and a centre of gravity of 1.8 m above the ground. The four drop orientations are illustrated below. Figure 5 Drop orientations No attempt shall be made to prevent the bouncing of containers, but the containers may be prevented from falling over during the vertical drop test described in b) above. If more than one container is used to execute all three drop specifications, then those containers shall undergo pressure cycling according to 2.2.2. until either leakage or 22,000 cycles without leakage have occurred. Leakage shall not occur within number of Cycles (5,500, 7,500 or 11,000). The orientation of the container being dropped per requirement 5.1.2.2. shall be identified as follows: (a) If a single container was subjected to all four drop orientations, then the container being dropped per requirement of 5.1.2.2. shall be dropped in all four orientations; (b) If more than one container is used to execute the four drop orientations, and if all containers reach 22,000 cycles without leakage, then the orientation of the container being dropped per requirement 5.1.2.2. is the 45o orientation (iv), and that container shall then undergo further testing as specified in paragraph 5.1.2.; (c) If more than one container is used to execute the four drop orientations and if any container does not reach 22,000 cycles without leakage, then the new container shall be subjected to the drop orientation(s) that resulted in the lowest number of cycles to leakage and then will undergo further testing as specified in paragraph 5.1.2. 1.8m > 488J < 1.8 m 45o > 0.6m No. 1 N o.2 No. 3* No. 4 center of gravity 36 قرار مجلس الوزراء لسنة2021 بشأن النظام الإماراتي للمركبات الهيدروجينية 2.3.3. Surface damage test (unpressurized) The test proceeds in the following sequence: (a) Surface flaw generation: Two longitudinal saw cuts are made on the bottom outer surface of the unpressurized horizontal storage container along the cylindrical zone close to but not in the shoulder area. The first cut is at least 1.25 mm deep and 25 mm long toward the valve end of the container. The second cut is at least 0.75 mm deep and 200 mm long toward the end of the container opposite the valve; (b) Pendulum impacts: The upper section of the horizontal storage container is divided into five distinct (not overlapping) areas 100 mm in diameter each (see Figure 6). After 12 hours preconditioning at – 40 °C in an environmental chamber, the centre of each of the five areas sustains the impact of a pendulum having a pyramid with equilateral faces and square base, the summit and edges being rounded to a radius of 3 mm. The centre of impact of the pendulum coincides with the centre of gravity of the pyramid. The energy of the pendulum at the moment of impact with each of the five marked areas on the container is 30 J. The container is secured in place during pendulum impacts and not under pressure. Figure 6 Side view of tank 2.3.4. Chemical exposure and ambient temperature pressure cycling test Each of the 5 areas of the unpressurized container preconditioned by pendulum impact (paragraph 4.2.5.2.) is exposed to one of five solutions: (a) 19 per cent (by volume) sulphuric acid in water (battery acid); (b) 25 per cent (by weight) sodium hydroxide in water; (c) 5 per cent (by volume) methanol in gasoline (fluids in fuelling stations); (d) 28 per cent (by weight) ammonium nitrate in water (urea solution); and (e) 50 per cent (by volume) methyl alcohol in water (windshield washer fluid). The test container is oriented with the fluid exposure areas on top. A pad of glass wool approximately 0.5 mm thick and 100 mm in diameter is placed on each of the five preconditioned areas. A sufficient amount of the test fluid is applied to the glass wool sufficient to ensure that the pad is wetted across its surface and through its thickness for the duration of the test. “Side” View of Tank “Side” View of Tank 37 قرار مجلس الوزراء لسنة2021 بشأن النظام الإماراتي للمركبات الهيدروجينية The exposure of the container with the glass wool is maintained for 48 hrs with the container held at 125 per cent NWP )applied hydraulically( and 20 )±5( °C before the container is subjected to further testing. Pressure cycling is performed to the specified target pressures according to paragraph 2.2.2. at 20 (±5) °C for the specified numbers of cycles. The glass wool pads are removed and the container surface is rinsed with water the final 10 cycles to specified final target pressure are conducted. 2.3.5. Static pressure test (hydraulic) The storage system is pressurized to the target pressure in a temperature-controlled chamber. The temperature of the chamber and the non-corrosive fuelling fluid is held at the target temperature within ±5°C for the specified duration. 2.4. Test procedures for expected on-road performance (5.1.3.) (Pneumatic test procedures are provided; hydraulic test elements are described in 3.2.) 2.4.1. Gas pressure cycling test (pneumatic) At the onset of testing, the storage system is stabilized at the specified temperature, relative humidity and fuel level for at least 24 hrs. The specified temperature and relative humidity is maintained within the test environment throughout the remainder of the test. (When required in the test specification, the system temperature is stabilized at the external environmental temperature between pressure cycles.) The storage system is pressure cycled between less than 2(+0/-1) MPa and the specified maximum pressure (±1MPa). If system controls that are active in vehicle service prevent the pressure from dropping below a specified pressure, the test cycles shall not go below that specified pressure. The fill rate is controlled to a constant 3-minute pressure ramp rate, but with the fuel flow not to exceed 60 g/s; the temperature of the hydrogen fuel dispensed to the container is controlled to the specified temperature. However, the pressure ramp rate should be decreased if the gas temperature in the container exceeds +85°C. The defuelling rate is controlled to greater than or equal to the intended vehicle’s maximum fuel-demand rate. The specified number of pressure cycles is conducted. If devices and/or controls are used in the intended vehicle application to prevent an extreme internal temperature, the test may be conducted with these devices and/or controls (or equivalent measures). 2.4.2. Gas permeation test (pneumatic) A storage system is fully filled with hydrogen gas at 115 per cent NWP (full fill density equivalent to 100 per cent NWP at +15 °C is 113 per cent NWP at +55 °C( and held at  +55 °C in a sealed container until steady-state permeation or 30 hours, whichever is longer. The total steady-state discharge rate due to leakage and permeation from the storage system is measured. 2.4.3. Localized gas leak test (pneumatic) A bubble test may be used to fulfil this requirement. The following procedure is used when conducting the bubble test: (a) The exhaust of the shutoff valve (and other internal connections to hydrogen systems) shall be capped for this test (as the test is focused at external leakage). 38 قرار مجلس الوزراء لسنة2021 بشأن النظام الإماراتي للمركبات الهيدروجينية At the discretion of the tester, the test article may be immersed in the leak-test fluid or leak-test fluid applied to the test article when resting in open air. Bubbles can vary greatly in size, depending on conditions. The tester estimates the gas leakage based on the size and rate of bubble formation. (b) Note: For a localized rate of 0.005 mg/sec (3.6 NmL/min), the resultant allowable rate of bubble generation is about 2,030 bubbles per minute for a typical bubble size of 1.5 mm in diameter. Even if much larger bubbles are formed, the leak should be readily detectable. For an unusually large bubble size of 6 mm in diameter, the allowable bubble rate would be approximately 32 bubbles per minute. 2.5. Test procedures for service terminating performance in fire ( 5.1.4.) 2.5.1. Fire test The hydrogen container assembly consists of the compressed hydrogen storage system with additional relevant features, including the venting system (such as the vent line and vent line covering) and any shielding affixed directly to the container (such as thermal wraps of the container(s) and/or coverings/barriers over the TPRD(s)). Either one of the following two methods are used to identify the position of the system over the initial (localized) fire source: 2.5.1.1. Method 1: Qualification for a generic (non-Specific) vehicle installation If a vehicle installation configuration is not specified (and the qualification of the system is not limited to a specific vehicle installation configuration) then the localized fire exposure area is the area on the test article farthest from the TPRD(s). The test article, as specified above, only includes thermal shielding or other mitigation devices affixed directly to the container that are used in all vehicle applications. Venting system(s) (such as the vent line and vent line covering) and/or coverings/barriers over the TPRD(s) are included in the container assembly if they are anticipated for use in any application. If a system is tested without representative components, retesting of that system is required if a vehicle application specifies the use of these type of components. 2.5.1.2. Method 2: Qualification for a specific vehicle installation If a specific vehicle installation configuration is specified and the qualification of the system is limited to that specific vehicle installation configuration, then the test setup may also include other vehicle components in addition to the hydrogen storage system. These vehicle components (such as shielding or barriers, which are permanently attached to the vehicle’s structure by means of welding or bolts and not affixed to the storage system) shall be included in the test setup in the vehicle-installed configuration relative to the hydrogen storage system. This localized fire test is conducted on the worst case localized fire exposure areas based on the four fire orientations: fires originating from the direction of the passenger compartment, cargo/luggage compartment, wheel wells or ground-pooled gasoline. The container may be subjected to engulfing fire without any shielding components, as described in paragraph 2.5.2. The following test requirements apply whether Method 1 or 2 (above) is used: 39 قرار مجلس الوزراء لسنة2021 بشأن النظام الإماراتي للمركبات الهيدروجينية (a) The container assembly is filled with compressed hydrogen gas at 100 per cent of NWP. The container assembly is positioned horizontally approximately 100 mm above the fire source. (Note: as stated in 5.1.4., contracting parties under the 1998 Agreement may choose to use compressed air as an alternative test gas for certification of the container for use in their countries or regions.) ; Localized portion of the fire test (b) The localized fire exposure area is located on the test article furthest from the TPRD(s). If Method 2 is selected and more vulnerable areas are identified for a specific vehicle installation configuration, the more vulnerable area that is furthest from the TPRD(s) is positioned directly over the initial fire source; (c) The fire source consists of LPG burners configured to produce a uniform minimum temperature on the test article measured with a minimum 5 thermocouples covering the length of the test article up to 1.65 m maximum (at least 2 thermocouples within the localized fire area, and at least 3 thermocouples equally spaced and no more than 0.5 m apart in the remaining area) located 25 mm ± 10mm from the outside surface of the test article along its longitudinal axis. At the option of the manufacturer or testing facility, additional thermocouples may be located at TPRD sensing points or any other locations for optional diagnostic purposes; (d) Wind shields are applied to ensure uniform heating; (e) The fire source initiates within a 250 mm ±50 mm longitudinal expanse positioned under the localized exposure area of the test article. The width of the fire source encompasses the entire diameter (width) of the storage system. If Method 2 is selected, the length and width shall be reduced, if necessary, to account for vehicle-specific features; (f) As shown in Figure 7 the temperature of the thermocouples in the localized fire area has increased continuously to at least 300 °C within 1 minute of ignition, to at least 600 °C within 3 minutes of ignition, and a temperature of at least 600 °C is maintained for the next 7 minutes. The temperature in the localized fire area shall not exceed 900 °C during this period. Compliance to the thermal requirements begins 1 minute after entering the period with minimum and maximum limits and is based on a 1-minute rolling average of each thermocouple in the region of interest. (Note: The temperature outside the region of the initial fire source is not specified during these initial 10 minutes from the time of ignition.). 40 قرار مجلس الوزراء لسنة2021 بشأن النظام الإماراتي للمركبات الهيدروجينية Figure 7 Temperature profile of fire test Engulfing portion of the fire test Within the next 2-minute interval, the temperature along the entire surface of the test article shall be increased to at least 800 °C and the fire source is extended to produce a uniform temperature along the entire length up to 1.65 meters and the entire width of the test article (engulfing fire). The minimum temperature is held at 800°C, and the maximum temperature shall not exceed 1100 °C. Compliance to thermal requirements begins 1 minute after entering the period with constant minimum and maximum limits and is based on a 1-minute rolling average of each thermocouple. The test article is held at temperature (engulfing fire condition) until the system vents through the TPRD and the pressure falls to less than 1 MPa. The venting shall be continuous (without interruption), and the storage system shall not rupture. An additional release through leakage (not including release through the TPRD) that results in a flame with length greater than 0.5 m beyond the perimeter of the applied flame shall not occur. 1 600o C 800o C Localized Fire Exposure Engulfing Fire Minutes 12 10 300o C 3 Min Temp Localized Area Engulfing Region Outside Localized Area (burner ramp rate) Ignite Main Burner 0 41 قرار مجلس الوزراء لسنة2021 بشأن النظام الإماراتي للمركبات الهيدروجينية Table 2 Summary of fire test protocol Localized fire region Time period Engulfing fire region (Outside the localized fire region) Action Ignite Burners 0-1 minute No Burner Operation Minimum temperature Not specified Not specified Maximum temperature Less than 900oC Not specified Action Increase temperature and stabilize fire for start of localized fire exposure 1-3 minutes No Burner Operation Minimum temperature Greater than 300oC Not specified Maximum temperature Less than 900oC Not specified Act
