Defines the design, performance, test procedures and quality assurance for types of heat-shrinkable sleeving used for insulation, binding and the purpose of identification. Quality and routine tests are also covered. Sleeves can be used in aerospace and non-aerospace applications.

This part of BS G 198 specifies the design, performance, quality assurance and methods of test for the types of heat-shrinkable sleeving shown in Table 1 and Table 2. These sleeves are for binding, insulation and identification purposes. Routine and quality tests are also specified.

These sleeves may be used in both aerospace and non-aerospace applications.

When specified, sleeves used with bonding adhesives and/or heat-shrinkable moulded shapes should conform to the compatibility test requirements detailed in part 5.

In addition to the definitive requirements, this standard also requires the items detailed in clause 3 to be documented. For compliance with this standard, both the definitive requirements and the documented items have to be satisfied.

NOTE 1 Recommendations for the storage of finished sleeves is given in annex A.

NOTE 2 The latest revision of an Aerospace Series standard is indicated by a prefix number.

NOTE 3 Sleeving that has been shrunk is referred to as recovered.
