This part of IEC 60684 gives the requirements for six types of general purpose, heat shrinkable dual wall polyolefin sleevings, flame retarded with nominal shrink ratios of 2:1, 3:1 or 4:1 and available in low and high temperature adhesive inner walls. The low temperature adhesive sleeving has been found suitable for temperatures up to 105 °C and the high temperature adhesive sleeving has been found suitable for temperatures up to 125 °C. - Type AL: 2:1 shrink ratio, internal diameter up to 51 mm, low temperature adhesive inner wall. - Type AH: 2:1 shrink ratio, internal diameter up to 51 mm, high temperature adhesive inner wall. - Type BL: 3:1 shrink ratio, internal diameter up to 40 mm, low temperature adhesive inner wall. - Type BH: 3:1 shrink ratio, internal diameter up to 40 mm, high temperature adhesive inner wall. - Type CL: 4:1 shrink ratio, internal diameter up to 52 mm, low temperature adhesive inner wall. - Type CH: 4:1 shrink ratio, internal diameter up to 52 mm, high temperature adhesive inner wall. The sleeving consists of an outer layer being of a flexible cross-linked polyolefin. The inner wall consists of a hot melt adhesive that flows and fuses during the shrinking process to provide a bond. These sleevings are normally supplied in colour black. Sizes or colours other than those listed in this standard may be available as custom items. These items are considered to comply with this standard if they comply with the property requirements listed in Tables, 5 and 6 and Table 8 where applicable, with the exception of dimensions. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone.
