15、ne, general purpose 1 Scope This part of IEC 60684 gives the requirements for non-heat-shrinkable sleeving, extruded from compounds based on polychloroprene elastomer.This sleeving has been found suitable for temperatures up to 95 C. Sleeving of this type is normally available with internal diameter
16、s up to 25 mm, and in the following opaque colours: black, brown, red, orange, yellow, green, blue, violet, grey, white and pink. Sizes or colours other than those specifically listed in this standard may be available as custom items. These items shall be considered to comply with this standard if t
17、hey comply with the other property requirements listed in Table 2. 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 perform
18、ance in the application and not based on the specification alone. 2 Normative references The following referenced documents are indispensable for the application of this document.
