of this annex is the test procedures for performance durability (requirement of paragraph 5.2. of this Regulation)
         Paragraph 4 of this annex is the test procedures for expected on-road performance (requirement of paragraph 5.3. of this Regulation)
         Paragraph 5 of this annex is the test procedures for service terminating performance in fire (requirement of paragraph 5.4. of this Regulation)
         Paragraph 6 of this annex is the test procedures for performance durability of primary closures (requirement of paragraph 5.5. of this Regulation)
         2. Test procedures for baseline performance metrics (requirement of paragraph 5. 1. of this Regulation)
         2.1. Burst test (hydraulic)
         The burst test is conducted at the ambient temperature of 20 (±5) °C using a non-corrosive fluid.
         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. The container temperature may vary from the environmental temperature during testing;
              (c) The container is pressure cycled between 2 (±1) MPa and the target pressure at a rate not exceeding 10 cycles per minute for the specified number of cycles;
              (d) The temperature of the hydraulic fluid within the container is maintained and monitored at the specified temperature.
         3. Test procedures for performance durability (requirement of paragraph 5.2. of this Regulation)
         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.
         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.
         The orientation of the container being dropped (in accordance with the requirement of paragraph 5.2.2.) 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
