24、eat-shrinkable chlorinated polyolefin sleeving, flame retarded, nominal shrink ratio 1,7:1 and 2:1 for use at temperatures up to 120 C. These sleevings are normally supplied with internal diameters up to 102 mm, and the standard colour is black. Sizes or colours other than those specifically listed
25、in this standard may be available as custom items. These items shall be considered to comply with this standard if they comply with the property requirements listed in Tables 3, 4 and 5 except for dimensions and mass, and Table 6, as applicable. Materials which conform to this specification meet est
