标准摘要
[中文适用范围]： ISO 15859 的这一部分规定了无水肼 (N2H4) 的成分和物理性质的限值，并制定了适用于验证无水肼成分的取样和测试要求。 ISO 15859 的本部分适用于无水肼推进剂，旨在用作空间系统推进剂系统以及以下等级的飞行硬件和地面设施、系统和设备中的燃料。 — 标准：正常生产和质量控制（适合大多数用途）。 — 单组元推进剂：严格控制指定杂质的普通产品（仅指定用于需要延长催化剂寿命的单组元推进剂催化发动机）。 — 高纯度：特殊生产，严格控制指定杂质。 ISO 15859 的这一部分仅适用于此处指定限值内的流入物。 肼可以是液体类型。 ISO 15859 的这一部分适用于任何所需的采样操作，以确保当流体进入运载火箭或航天器时，流体成分符合下文提供的限制或符合针对特定用途商定的任何技术规范。 [外文原描述]： ISO 15859-7:2004 specifies limits for the composition and physical properties of anhydrous hydrazine (N 2 H 4 ) and establishes the sampling and test requirements applicable for the verification of the anhydrous hydrazine composition. ISO 15859-7:2004 is applicable to anhydrous hydrazine propellant, intended for use as fuel in propellant systems of space systems as well as in both flight hardware and ground facilities, systems, and equipment, of grades: standard [normal production and quality control (suitable for most uses)], monopropellant [normal product with strict control of specified impurities (to be specified only for monopropellant catalytic engines where extended life of the catalyst is desired)] and high purity (special production with strict control of specified impurities). ISO 15859-7:2004 is applicable to influents only within the specified limits herein. Hydrazine may be of the liquid type. ISO 15859-7:2004 is applicable to any sampling operation required to ensure that, when the fluid enters the launch vehicle or spacecraft, the fluid composition complies with the limits provided hereafter or with any technical specification agreed to for a particular use.
