ASTM F1837M-97(2018)

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.
