BS EN 4708-101:2017EN 4708-101:2017 (E) 4 1 Scope This European Standard specifies the required characteristics for four types of heat-shrinkable
18、polyolefin sleevings for use in aircraft electrical systems at operating temperatures between 55 C and 135 C. Type A: Very flexible, flame retarded, shrink ratio 2:1 This sleeving has very good flexibility, is flame retarded and will shrink at low temperatures. It is suitable where sensitive compone
19、nts and delicate wiring need protection from excessive heat during shrinking. Type B: Flexible, flame retarded, shrink ratio 2:1, 3:1 and 4:1 This sleeving is flexible and flame retarded. It is suitable for general purposes and is available with high shrink ratios. Type C: Flexible, not flame retard
20、ed, shrink ratio 2:1 and 3:1 This sleeving is flexible and not flame retarded and is available in two shrink ratios. Type D: Semi-rigid, flame retarded, shrink ratio 2:1 This sleeving is semi-rigid and flame retarded. It is suitable where strain relief and mechanical support are required These sleev
21、ings are normally supplied with internal diameters up to 102 mm for shrink ratios of 2:1 and 4:1 and up to 39 mm for shrink ratios of 3:1 and in the following colours for type B, black, brown, red, yellow, green, blue, orange, violet, grey, white and green/yellow. Types A and D are black only. Type
22、C is transparent, is not flame retarded and does not meet the flammability requirements of EN 4708-001. Sizes or colours other than those specifically listed in this standard may be available. These items shall be considered to comply with this standard if they comply with the property requirements
