ASTM F1836M-97(2002)

Standard Specification for Stuffing Tubes, Nylon, and Packing Assemblies (Metric)

SCOPE
1.1 This specification covers the general requirements for nylon stuffing tubes and packing assemblies. Nylon stuffing tubes are intended for making electric cable penetrations in marine shipboard enclosures for electrical equipment. The following types are suitable for both thin-wall enclosures up to 5 mm (3/16 in.) thick and thick-wall enclosures, bulkheads, and decks of 5 to 19 mm (3/16 to 3/4 in.) thick.  
1.2 This specification does not cover metal stuffing tubes.  
1.3 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 use.
