[Current]Elastomeric seals — Material requirements for pipe joint seals used in water and drainage applications, Part 2: Thermoplastic elastomers
Specifies requirements for materials used for moulded seals only of thermoplastic elastomers (TPE) used in joints of thermoplastic piping systems for gravity waste water discharge (intermittent flow up to 95 degrees Celsius) inside buildings, thermoplastic piping systems for gravity underground drainage and sewerage (continuous flow up to 45 degrees Celsius and intermittent flow up to 95 degrees Celsius), and thermoplastic rainwater piping systems.
