Elastomeric seals. Material requirements for pipe joint seals used in water and drainage applications - Vulcanized rubber Ingestion-build-183511 non-electrical special fire detectoWhat is BS EN 681 Material requirements for vulcanized rubber seals about? BS EN 681 is a series on elastomeric seals. Elastomeric seals are a polymer with viscoelasticity (i. e., both viscosity and elasticity) and with weak intermolecular forces, generally low Young's modulus and high failure strain compared with other materials. BS EN 681 1 specifies requirements for materials used in vulcanized rubber seals for: Cold potable water supply (up to 50
