25、pe This document specifies the required characteristics for heat-shrinkable adhesive lined polyolefin sleevings for use in aircraft electrical systems at operating temperatures between 55 C and 105 C. The sleeving consists of an outer layer being of a flexible cross-linked polyolefin. The inner wall

26、 consists of a hot melt adhesive that flows and fuses during the shrinking process to provide a bond that is suitable where an environmental seal is required. These sleevings are normally supplied with internal diameters up to 40 mm for shrink ratios of 3:1 and up to 52 mm for shrink ratios of 4:1.

27、These sleevings are normally supplied in colour black. Sizes or colours other than those specifically listed 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 Table 3 and Table 5 exc
