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, govern- mental and non-governmental, in liaison with Iso, also take part in the work. DraftInternational Standardsadoptedbythetechnical committeesarecirculatedto the member bodies for approval before their acceptance as International Standards by the Iso Council. They are approved in accordance with Iso procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 8479 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles. Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other international Standard implies its latestedition,unlessotherwisestated.

These clamps are intended for the installation, support and guiding of rigid tubing or hose assemblies used in aerospace equipment. 5 Description NOTE -- "Q" clamps of sizes larger than DN 50 are not suitable for The"Q" clamp (centre-mounted clamp) is a"single-block" or a supporting tubing or hose assemblies; they may be used for other "multi-component"-type clamp.
