Ships and marine technology. Fire resistance of metallic pipe components with resilient and elastomeric seals. Test methods Ingestion-build-228203 They are non-reciprocal optical devices1 Scope This International Standard specifies test procedures for determining the fire resistance of metallic valves, pipe couplings, and similar pipe components which contain a resilient or elastomeric seal and which are used in ship engineering systems. The purpose of this International Standard is to determine whether, after the period of fire testing on a test bench which fulfils the requirements of ISO 19922, pipeline components remain tight, and
