DANSK DS/ISO 19921 PDF

This International Standard specifies test procedures for determining the fire resistance of pipe couplings which contain an elastomeric seal and which are used in ship engineering systems.
The components to be tested contain non-metallic material, e.g. the sleeve of pipe couplings.
The purpose of this standard is to prove that, after the period of fire testing in the test bench in accordance with ISO 19922, pipeline components continue to remain tight, and without any failure which may affect the function, even when subjected to proof pressure
