19、45:2002-48606-3543 ot 343 2002:CEI 3 INTRODUCTION This International Standard is one of a series which deals with flexible insulating sleeving for electrical purposes. The series consists of three parts: Part 1: Definitions and general requirements (IEC 60684-1); Part 2: Methods of test (IEC 60684-2
20、); Part 3: Specifications for individual types of sleeving (IEC 60684-3). This standard contains three of the sheets comprising Part 3, as follows: Sheet 343: Expandable braided ethylene chlorotrifluoroethylene (E-CTFE) textile sleeving, uncoated, thin wall thickness Sheet 344: Expandable braided et

22、t 3: Specifications for individual types of sleeving Sheets 343 to 345: Expandable braided ethylene chlorotrifluoroethylene (E-CTFE) textile sleeving, uncoated 1 Scope This International Standard gives the requirements for sleeving having the property of expanding its internal diameter when compress
23、ed longitudinally and thereafter returning to its initial diameter after release of the compressing force. This expandable braided textile sleeving, uncoated, is constructed of ethylene chlorotrifluoroethylene (E-CTFE) monofilament yarns suitably processed to provide the mechanical ability to confor
24、m in the manner described above. 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 three levels of wall thickness (thin (sheet 343), medium (sheet 344), and thick (sheet 345). It is nor
25、mally 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 val
26、ue for this property should be given in the purchase contract, but a typical value is 1,5 kV/mm wall thickness, although a linear relationship cannot be assumed.) However, it serves to provide mechanical protection to circuit components such as wires, sleeves, and flat cable over which it is applied
27、 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 actual requirements necessary for adequate performance in that application and not
28、based on this specification alone. 2 Normative references The following referenced documents are indispensable for the application of this document.
