气态氢 加油站 第9部分：燃料质量分析取样

[中文适用范围]： 本文件概述了从加氢站分配器取样的要求。该文件定义了在加氢站喷嘴取样的最佳实践，这是加氢站验收测试和持续运行的一部分。此外，该文件还描述了取样的最低安全要求。本文件针对从加氢站分配器取样。本文件中的许多通用要求适用于在加氢站内其他位置取样，这些取样可用于保证氢气质量，参见 ISO 19880-8，但是，本文件未涉及安全取样所需的进一步具体要求。对氢气取样的目的是能够根据 ISO 14687 的要求进行分析，并通过 ISO 21087 中描述的协议验证的分析方法进行分析。本文件取代并扩展了 ISO 19880-1:2020 附件 K 中发布的指南。注意分析方法分为在线分析和离线分析。在线分析允许在氢气站进行实时分析，但本文档未涉及该内容。 [外文原描述]： This document outlines requirements for sampling from hydrogen fuelling stations for samples taken at the dispenser. The document defines the best practice for sampling at the nozzle of a hydrogen fuelling station as part of the fuelling station acceptance testing, and ongoing operation. Further, the document describes the minimum safety requirements for sampling. This document is targeted for the sampling from the hydrogen fuelling station dispenser. Many of the generic requirements within this document are applicable to sampling at other locations within the hydrogen fuelling station, which can be carried out for hydrogen quality assurance, see ISO 19880-8, however, further specific requirements that can be necessary for safe sampling are not addressed in this document. The intention of sampling hydrogen is to enable analysis against the requirements of ISO 14687, and by analytical methods validated by protocols described in ISO 21087. This document supersedes, and is an extension to, the guidance published in ISO 19880-1:2020, Annex K. NOTE Analytical methods are divided into on-line analyses and off-line analyses. On-line analysis allows for real time analysis at hydrogen stations and is not covered in this document.
