適用范圍：This International Standard gives the requirements for sleeving having the property ofexpanding its internal diameter when compressed longitudinally and thereafter returning toits initial diameter after release of the compressing force. This expandable braided textilesleeving, uncoated, is constructed of ethylene chlorotrifluoroethylene (E-CTFE) monofilamentyarns suitably processed to provide the mechanical ability to conform in the manner describedabove. These sleevings have been found suitable for use at temperatures up to 155 C.This sleeving is normally supplied in internal diameters between 6 mm and 63 mm and in threelevels of wall thickness (thin (sheet 343), medium (sheet 344), and thick (sheet 345)). It isnormally supplied in the following colours: black, white, brown, red, orange, yellow, green, blue,grey, and natural.Because of its open construction, this sleeving is normally used to provide air-space insulation.Therefore, no requirement for breakdown voltage is specified in this standard. (Any value forthis property should be given in the purchase contract, but a typical value is 1,5 kV/mm wallthickness, although a linear relationship cannot be assumed.) However, it serves to providemechanical protection to circuit components such as wires, sleeves, and flat cable over which itis applied as a containing wrap or harness.Materials which conform to this specification meet established levels of performance. However,the selection of a material by a user for a specific application should be based on the actualrequirements necessary for adequate performance in that application and not based on thisspecification alone.
