Ships and marine technology. Gasketed mechanical couplings for use in piping systems. Performance specification Ingestion-build-54371 BS EN 349:1993 specifies minimum1 Scope This International Standard provides the performance characteristics and qualification tests required for gasketed mechanical couplings, including grooved type mechanical couplings for grooved end pipe, mechanical restraint couplings for plain end pipe and mechanical compression couplings for plain end pipe. These couplings are for use at temperatures within the recommended temperature range of their respective gaskets.
