What 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 degrees C)
Hot potable and non-potable water supply (up to 110 degrees C)
