Overview
EN 681-2:2000 - Elastomeric Seals: Materials requirements for pipe joint seals used in water and drainage applications - Part 2: Thermoplastic Elastomers (TPE) - specifies material requirements for moulded TPE seals used in non-pressure thermoplastic piping systems. The standard addresses seals for indoor wastewater (intermittent flow up to 95°C), underground drainage and sewerage (continuous up to 45°C, intermittent up to 95°C), and thermoplastic rainwater piping. It also provides general requirements for finished joint seals while noting that additional, application-specific requirements are set out in relevant product standards.
Key Topics

- Temperature performance limits
- Intermittent service up to 95°C (indoor wastewater and intermittent flow cases).
- Continuous underground drainage up to 45°C; intermittent exposure up to 95°C.
- Material characteristics
- Requirements focus on the suitability of thermoplastic elastomers (TPE) for long-term sealing performance.
- Emphasis on properties that influence sealing: compound quality, aging resistance, and dimensional stability.
