The work of preparing International Standards is normally carried out through ISO 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. adopted by the technical committees are circulated to the member bodies for voting. Publication as an Attention is drawn to the possibility that some of the elements of this document may be the subject of patent ISO 15860 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC14,Spacesystemsandoperations. iv ISO 2006 -All rights reserved ISO 15860:2006(E) Introduction This International Standard establishes the impurities contamination measurement methods for real compressed gas (air, nitrogen, helium, and argon) used in systems and facilities of space launch and technica complexes. This International Standard provides recommendations for correct selection and use of compressed gas contamination measurement methods and means. that reduces their life and reliability. Oil impurities in contact with oxidizer increase equipment explosion and fire equipment as specified. This International Standard can be used for modernization and maintenance of launch site equipment and Standard is portable, compact and inexpensive. @ ISO 2006 - All rights reserved ISO 15860:2006(E) INTERNATIONAL STANDARD Space systems Gas contamination Measurement methods for field tests 1 Scope This International Standard covers gases (air, nitrogen, helium, and argon) compressed up to 4o MPa used
