This document specifies the required characteristics for two types a heat-shrinkable, fluoroelastomer sleeving for use in aircraft electrical systems at operating temperatures between -55 °C and 200 °C. Type A Thick wallType B Thin wall This sleeving has good flexibility, is flame retarded and has a thick wall for mechanical protection. It is for use in areas subject to prolonged contamination by aircraft fuel and fluids with the exception of phosphate ester-based hydraulic fluids. The standard colour is black. These sleevings are normally supplied with internal diameters up to 50 mm for shrink ratios of 2:1. They are available in black only. Sizes 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 listed in Tables 2, 3 and 4 except for dimensions and mass.Cross References:IEC 60684-1EN ISO 846EN ISO 1817EN 4708-001EN 3909IEC 60684-2IEC 60757All current amendments available at time of purchase are included with the purchase of this document.
