9、. The work of preparing International Standards is normally carried out through ISO technical committees. 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
10、-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
11、 2. The main task of technical committees is to prepare International Standards. Draft International Standards 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
12、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 22108 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcomm

14、ISO 2008 All rights reserved Introduction It is essential that non-flight items which have been used for test, safety or as production aids are removed from flight hardware before flight, so that they do not interfere with mission performance. In order to achieve that requirement, positive identific
15、ation of such non-flight items is needed. A log needs to be maintained of all critical non-flight items pertaining to a stated piece of flight hardware. Each item needs to be identified by coloured streamers and covers as appropriate. Upon removal from the hardware, evidence of removal needs to be r
16、ecorded for each item, e.g. by placing the item in a dedicated accountability box that is then photographed when full to demonstrate complete removal of all non-flight items from the hardware. This International Standard addresses the identification of non-flight items and the control measures requi
17、red to ensure their removal before launch. Throughout this International Standard, the minimum essential criteria are identified by the use of the key word “shall”. Recommended criteria are identified by the use of the key word “should”, and while not mandatory, are considered to be of primary impor
18、tance in providing serviceable, economical and practical procedures. Deviation from the recommended criteria is acceptable only after careful consideration, extensive testing and thorough service evaluation have shown alternative methods to be satisfactory.

20、flight hardware Identification and control 1 Scope This International Standard describes the identification of critical non-flight items in space flight hardware and the procedure to account for their complete removal prior to flight. This International Standard is used in context with project-speci
21、fic quality requirements and procedures related to flight hardware and related activities prior to launch and at the launch site. Verification of removal of critical non-flight items is described in this International Standard. Removal of other non-flight items is outside the scope of this Internati
22、onal Standard and is verified by relevant inspection procedures. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 critical non-flight item item of non-flight equipment whose presence in or on launched flight hardware would severely jeopardise
23、mission performance EXAMPLE Protective equipment cover, safety device, locking pin, fastener, ground support interface equipment. 2.2 other non-flight item item of non-flight equipment that is not considered in the procedure described in this International Standard EXAMPLE Tape and connector caps th
