This specification covers the general requirements for heat-shrink cable entry seals. Cable entry seals are intended for making electrical cable penetrations into connection boxes, bulkheads, or other enclosures. Heat-shrink cable entry seals shall be of the following types: Type I (Types I-1, I-2, I-3, I-4, I-5, and I-6); Type II (Types II-1, II-2, II-3, and II-4); Type III; and Type IV. The rigid plastic parts shall be made from polyamide (nylon), or polyester material, or both. The following tests shall be performed: conformance testing; mechanical abuse test; and level of effectiveness.

1.1 This specification covers the general requirements for heat-shrink cable entry seals. Cable entry seals are intended for making electrical cable penetrations into connection boxes, bulkheads, or other enclosures. These devices are suitable for both thin wall enclosures up to 5 mm (3/16 in.) thick and thick-wall enclosures of 5 mm to 19 mm (3/16 in. to 3/4 in.) thick.

1.2 Cable entry seals shall have factory-applied adhesive that provides the seal to wire and cable jackets.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to its use.
