The harmonized European standard EN 681-1 describes the requirements for elastomeric seals in vulcanized rubber in joints for water piping systems. The European Regulation for Construction Products demands these seals to comply with this standard and CE-marking is obligatory. For drinking water applications there is additional legislation in each European member state.
The EN 681-1 is often used as a reference for the formulation of requirements for rubber parts in assembled products. For the certification of assembled products one can refer to exsisting Kiwa evaluation guidelines to assure the application of certified rubber parts. The standard EN 681-1 often is used for the setting up of requirements to rubber parts in assembled products.
