24、Part 3: Specifications for individual types of sleeving Sheet 233: Heat-shrinkable fluoroelastomer sleeving, flame retarded, fluid resistant, shrink ratio 2:1 1 Scope This standard gives the requirements for two types of heat-shrinkable, flame retarded, fluid resistant1), nominal shrink ratio 2:1, f

25、luoroelastomer sleeving for use at temperatures up to 200 C: Type A: thick wall; Type B: thin wall. These sleevings are normally supplied with internal diameters up to 51 mm, and the standard colour is black. Sizes or colours other than those specifically listed in this standard may be available as

26、custom items. These items shall be 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 m
