General Information

Abstract

This standard specifies requirements for materials used in vulcanized rubber seals for: a) cold potable water supply (up to 45°C); 2) hot potable and non-potable water supply (up to 110°C); 3) drainage, sewerage and rainwater systems (continuous flow up to 45°C and intermittent flow up to 95°C). The different designations of seals specified are defined according to their type, application and requirements.

Overview

EN 681-1:1996 (CEN) specifies material requirements for elastomeric seals made from vulcanized rubber used as pipe joint seals in water and drainage systems. The standard defines the appropriate material properties and designations for seals used in cold and hot potable water, non-potable water, and drainage, sewerage and rainwater applications, with clear temperature limits and service conditions.

Key topics and requirements

  • Material scope: Focuses exclusively on vulcanized rubber materials for pipe joint seals (Part 1 of EN 681).
  • Service temperature classes:
    • Cold potable water supply: up to 45°C
    • Hot potable and non‑potable water supply: up to 110°C
    • Drainage, sewerage, rainwater systems: continuous flow up to 45°C and intermittent flow up to 95°C
  • Designation system: Seal types and designations are defined according to type, application and specific requirements, enabling manufacturers and specifiers to match material grades to intended service.
  • Application-focused material requirements: Ensures materials used in seals meet the performance expectations for contact with potable water, hot water, and wastewater environments.
  • Standards context: Part 1 is specific to vulcanized rubber; related parts address other elastomeric materials or aspects of seal design (see Related Standards).

(Note: EN 681-1:1996 sets material requirements and designation principles; specific test methods, dimensional standards or installation practices are addressed in other standards or parts.)

Practical applications

EN 681-1:1996 is applied where reliable sealing and hygiene or performance under temperature stress are required:

  • Water utility pipe joints for cold and hot potable water systems
  • Plumbing and sanitary installations handling hot water
  • Sewerage, drainage and rainwater piping systems with continuous or intermittent flows
  • Manufacturing and quality control of gaskets, O‑rings and profile seals for pipelines
  • Specification and procurement documents for infrastructure, building services and wastewater networks

Who uses this standard

  • Seal and gasket manufacturers - material selection and product designation
  • Plumbing and civil engineers - specifying compliant seals for projects
  • Water utility and infrastructure operators - ensuring compatibility with service conditions
  • Regulatory bodies and compliance teams - verifying materials for potable water contact
  • Test laboratories and quality assurance - confirming material conformity to EN 681‑1 requirements

Related standards

  • Other parts of EN 681 (for different elastomeric materials or additional requirements)
  • Complementary pipe, joint and installation standards from CEN and national bodies
