SO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). 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-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electromechanical Commission (IEC) on all matters of electrotechnical standardization.The main task of ISO technical committees is to prepare International Standards. In exceptional circumstances a technical committee may propose the publication of a technical report of one of the following types :
— type 1, when the necessary support within the technical committee cannot be obtained for the publication of an International Standard, despite repeated efforts;
— type 2, when the subject is still under technical development requiring wider exposure;
— type 3, when a technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art”, for example).
Technical reports are accepted for publication directly by ISO Council. Technical reports of types 1 and 2 are subject to review within three years of publication, to decide whether they can be transformed into International Standards. Technical reports of type 3 do not necessarily have to be reviewed until the data they provide are considered to be no longer valid or useful.ISO/TR 8647, which is a technical report of type 3, was prepared by Technical Committee ISO/TC 20, Aircarft and space vehicles.INTRODUCTIONThe lack of assembled information regarding deterioration of textiles used in air cargo equipment has become a matter of some concern. Typically, webbings or rope are used in pallet restraint nets, crash barrier net internal in aircraft, cargo retention straps, and other applications.These textile products have a service life based on environmental factors. Knowledge of their susceptibility to environmental deterioration is essential. Data on the subject has been fragmented and not specifically applicable.Cognizant Society of Engineers Committee AGE-2A, Aircraft Cargo Handling, sponsored a test program intended to provide more usable information directed to specific interests of the air cargo technical community. The first efforts have been expanded by others to include tests on newer materials coming into use.Results of these tests are published along with abstracts and bibliographies of previously published data.1. SCOPEThe intent of this Technical Report is to make available information concerning the environmental degradation of textiles as used in unit load device (ULD) equipment common to the air cargo community.Since the ULD device containing textiles should have a predictable service life, there should be data available from which the predictions can be made. This Technical Report compiles available information on textiles of the types used in air cargo ULD devices and reviews the degradation characteristics of each.Textiles are used primarily in cargo restraint nets on air cargo pallets and non structural containers, restraint nets installed in cargo aircraft, and similar applications.2.
