The work of preparing International Standards is normally carried out through IsO technicalcommittees.Eachmemberbodyinterestedinasubjectforwhichatechnicalcommitteehasbeer non-governmental, in liaison with IsO, also take part in the work. Iso collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. IsO shall not be held responsible for identifying any or all such patent rights. ISO 15859-9 was prepared by Technical Committee ISO/T 20, Aircraft and space vehicles, Subcommittee Sc 14, Space systems and operations. Iso 15859 consists of the following parts, under the general title Space systems - Fluid characteristics, sampling and test methods: Part 1: Oxygen Part 2: Hydrogen Part 3: Nitrogen Part 4: Helium Part 5: Nitrogen tetroxide propellants Part 6: Monomethylhydrazine propellant Part 7: Hydrazine propellant Part 8: Kerosine propellant Part 9: Argon Part 10: Water Part 11: Ammonia Part12:Carbon dioxide Part 13: Breathing air ii ISO 15859-9:2004(E) Introduction Fluid operations at a spaceport or launch site may involve a number of operators and supplier/customer IsO 15859 is to establish uniform requirements for the components, sampling and test methods of fluids used sampling and test methods are acceptable methods for verification of the fluid composition limits. iv @ ISO 2004 - All rights reserved E*eqr[tkijvgf"d["WPG.'E1"1gpqxc."8I"4:226"Ocftkf.'Urckp"cmn'tkijv'tgugtxgf+Ygf"Hgd’36*27<5878"WVE"4246 knni'rwrintiInfi ISO 15859-9:2004(E) INTERNATIONALSTANDARD Space systems Fluid characteristics, sampling and test methods : Part 9: Argon 1 Scope This part of IsO 15859 specifies limits for the composition of argon (Ar) and establishes the sa
