The work of preparing International Standards is normally carried out through Iso technical committees. Each member the right to be represented on that committee. International organizations, govern- mental and 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. 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: obtained for the publication of an International Standard, despite repeated efforts; 一 type 2, when the subject is still under technical development requiring wider exposure; type3,whenatechnical committeehascollecteddataofadifferentkindfrom 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to reports of type 3 do not necessarily have to be reviewed until the data they provide are considered to be no longer valid or useful.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 Com- mitteeISO/Tc20,Aircarftandspacevehicles.

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. sponsored a test program intended to provide more usable information directed to specific interests of the air cargo technical community. The first efforts have Results of these tests are published along with abstracts and bibliographies of previously published data. ii No reproduction or networking permited without license from IHS Not for Resale
