T/GERS 0021-2023 Hydrogen sampling standard for hydrogen fueling stations

Scope

Main technical content: (1) The standard framework includes terms and definitions for hydrogen gas sampling at hydrogen stations, safety requirements, sample containers, sampling devices, sampling requirements, and sample transportation and storage. (2) The main content of the standard and its determination basis This standard is written in accordance with the provisions of GB/T 1.1–2020. The relevant content has been verified and is highly operable and scientific. Based on the results of research and the collection of opinions, the main technical content of the standard is determined as follows: 1. Clarify the terms and definitions for hydrogen gas sampling at hydrogen stations, including hydrogen stations, indirect sampling, purging time, representative samples, sample containers, sampling ports, etc. 2. Clarify the safety requirements for hydrogen gas sampling, including provisions on general safety requirements, personnel safety, and equipment safety. 3. Clarify the requirements for sample containers, including provisions on the design, manufacture, and inspection of sample containers, as well as their sealing, inner wall treatment, and reuse. 4. Clarify the requirements for sampling devices, including provisions on the components of sampling devices, pipeline materials, pipeline connections, and inner wall treatment. 5. Clarify the sampling requirements, including provisions on sampling preparation, operational safety, and the application scenarios and sampling steps of two sampling methods (inflation and emptying method, controlled flow method). 6. Clarify the requirements for sample transportation and storage, including provisions on safety protection measures during sample transportation and storage, the provision of emergency rescue materials, protection of sample containers, storage locations, and storage times. 7. To better understand and apply this standard when sampling using the inflation and emptying method, the recommended number
