Abstract
Gives the requirements for two types of heat-shrinkable, flame retarded, fluid resistant, elastomer sleevings, with a nominal shrink ratio of 2:1 for use at temperatures up to 120 C.
Type A: Standard wall thickness
Type B: Thin wall thickness
These sleevings are normally supplied with internal diameters up to 102 mm for the standard wall thickness and up to 51 mm for the thin wall thickness.The standard colour is black.
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 requirements listed in Tables 3, 4, 5 and 6, except for 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 adequate performance in that application and not based on this specification alone.
This edition includes the following significant changes with regard to the previous edition:
- Replacement of the thermal endurance test method according to IEC 60216 with a long term ageing test i.e. 3 000 h at the recommended maximum temperature found suitable for use, in order to provide safe thermal test data within a workable time scale. It has also been combined with Sheet 272.
- Sheet 272 has been withdrawn.
