This standard specifies requirements of materials used for vulcanized rubber seals in: - Cold water (T 50 °C); - Cold water (T 50 °C) and intermittently hot water (T 95 °C); - Cold water (T 50 °C) and continuously hot water (T 110 °C). The different designations of seals specified are defined according to their type, application and requirements (see Table 1). This standard defines requirements for seals, partially defining the properties of the vulcanized rubber material as a performance indicator of the finished seal. Any additional requirements called for by the particular application are specified in the relevant product standards taking into account that the performance of pipe joints is a function of the seal material properties, seal geometry, pipe system material and pipe joint design. This standard should be used where appropriate with product standards which specify performance requirements for joints. It is applicable to elastomeric components of composite or non c
