20、lectrical purposes. The series consists of three parts: Part 1: Definitions and general requirements (IEC 60684-1) Part 2: Methods of test (IEC 60684-2) Part 3: Specifications for individual types of sleeving (IEC 60684-3) This standard is one of the sheets comprising Part 3, as follows: Sheet 228:

22、uoride sleeving, flame retarded, fluid resistant, shrink ratio 2:1 1 Scope This standard gives the requirements for one type of heat-shrinkable, flame retarded, with a nominal shrink ratio 2:1, fluid resistant polyvinylidene fluoride sleeving for use at temperatures up to 175 C. This sleeving is nor
23、mally supplied with an internal diameter up to 25,4 mm, and the standard colour is transparent. Sizes or colours other than those specifically listed in this standard may be available as custom items. These items are considered to comply with this standard if they comply with the property requiremen
24、ts listed in Tables 2, 3, 4 and 5, with the exception of dimensions and mass. 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 adequ
25、ate performance in that application and not based on this specification alone. 2 Normative references The following referenced documents are indispensable for the application of this document.
