The work of preparing International Standards is normally carried out through ISO technical committe
11、es. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Inte
12、rnational 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. The main task of technical committees is to prepare International Standards. Draft International S
13、tandards 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. ISO 14624-6 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcom
14、mittee SC 14, Space systems and operations. ISO 14624 consists of the following parts, under the general title Space systems Safety and compatibility of materials: Part 1: Determination of upward flammability of materials Part 2: Determination of flammability of electrical-wire insulation and access
