The work
11、of preparing International Standards is normally carried out through ISOtechnical committees. Each member body interested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. International organizations, governmental andnon-governmental,
12、 in liaison with ISO, also take part in the work. ISO collaborates closely with the InternationalElectrotechnical 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.The main task
13、 of technical committees is to prepare International Standards. Draft International Standardsadopted by the technical committees are circulated to the member bodies for voting. Publication as anInternational Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is
14、 drawn to the possibility that some of the elements of this document may be the subject of patentrights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 15860 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, SubcommitteeSC 14, Space syst
15、ems and operations.BS ISO 15860:2006vIntroductionThis International Standard establishes the impurities contamination measurement methods for realcompressed gas (air, nitrogen, helium, and argon) used in systems and facilities of space launch and technicalcomplexes.This International Standard provid
16、es recommendations for correct selection and use of compressed gascontamination measurement methods and means.Compressed gas impurities have a mechanical, physical, chemical, and electrolytic effect on pneumatic devicesthat reduces their life and reliability. Oil impurities in contact with oxidizer
17、increase equipment explosion and firehazards and have a negative biological effect when inhaled. Compressed gas impurity contamination is one ofthe normalized parameters subjected to careful monitoring to ensure reliable operation of space systemequipment as specified.This International Standard can
18、 be used for modernization and maintenance of launch site equipment andtechnical complexes when other methods are difficult to apply. The equipment mentioned in this InternationalStandard is portable, compact and inexpensive.BS ISO 15860:2006blank1Space systems Gas contamination Measurement methods
