Part I – Specifications of the compressed Clause Samples
The "Part I – Specifications of the compressed" clause defines the technical and operational requirements for any compressed materials or systems referenced in the contract. This section typically outlines the standards, measurements, and performance criteria that the compressed product must meet, such as pressure ratings, material composition, or testing protocols. By clearly specifying these details, the clause ensures that both parties have a mutual understanding of the expected quality and characteristics of the compressed goods, thereby reducing the risk of disputes over compliance or performance.
Part I – Specifications of the compressed hydrogen storage system
(a) TPRD;
(b) Check valve that prevents reverse flow to the fill line; and
(c) Automatic shut-off valve that can close to prevent flow from the container to the fuel cell or internal combustion engine. Any shut-off valve, and TPRD that form the primary closure of flow from the storage container shall be mounted directly on or within each container. At least one component with a check valve function shall be mounted directly on or within each container.
Figure 1 T ypical compressed hydrogen storage system All new compressed hydrogen storage systems produced for on-road vehicle service shall have a NWP of 70 MPa or less and a service life of 15 years or less, and be capable of satisfying the requirements of paragraph 5. The hydrogen storage system shall meet the performance test requirements specified in this paragraph. The qualification requirements for on-road service are:
5.1. Verification tests for baseline metrics
5.2. Verification test for performance durability (hydraulic sequential tests)
5.3. Verification test for expected on-road system performance (pneumatic sequential tests)
5.4. Verification test for service terminating system performance in Fire 5.5. Verification test for performance durability of primary closures. The test elements within these performance requirements are summarized in Table 1. The corresponding test procedures are specified in Annex 3. Table 1 5.1. 5.1.1. 5.1.2. Verification tests for baseline metrics Baseline initial burst pressure Baseline initial pressure cycle life
2.8. Verification test for performance durability (sequential hydraulic tests) Proof pressure test Drop (impact) test Surface damage Chemical exposure and ambient temperature pressure cycling tests High temperature static pressure test Extreme temperature pressure cycling Residual proof pressure test Residual strength Burst Test
