1.1 普通氢气的热物理性质表用于计算工艺设计和操作中氢气的压力-体积-温度（PVT）、热力学和传输性质，特别是与氢燃料电池应用有关的情况。提供了温度在50 K和500 K之间、压力到500 MPa的气态氢的表。这些表格是由美国国家标准与技术研究所根据标准参考数据库产品REFPROP 10.0版本开发的 2. . 1.2 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 The thermophysical property tables for normal hydrogen are for use in the calculation of the pressure-volume-temperature (PVT), thermodynamic, and transport properties of hydrogen for process design and operations, particularly as they relate to hydrogen fuel cell applications. Tables are provided for gaseous hydrogen at temperatures between 50 K and 500 K at pressures to 500 MPa. These tables were developed by the National Institute of Standards and Technology from a Standard Reference Database product REFPROP, version 10.0 2 . 1.2 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
