ISO 15859-7:2004 PDF

Scope: This part of ISO 15859 specifies limits for the composition and physical properties of anhydrous hydrazine (N2H4) and establishes the sampling and test requirements applicable for the verification of the anhydrous hydrazine composition. This part of ISO 15859 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 the following 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). — High purity: special production with strict control of specified impurities. This part of ISO 15859 is applicable to influents only within the specified limits herein. Hydrazine may be of the liquid type. This part of ISO 15859 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.
