Overview

EN 681-4:2000/A2:2005 is a CEN European standard that specifies material requirements for cast polyurethane sealing elements used as elastomeric pipe joint seals in water supply and drainage applications. This document is an amendment (A2) to EN 681-4:2000 and clarifies manufacturer obligations for factory production control and updates normative references. It is part of the EN 681 series addressing elastomeric seals for pipeline joints (ICS 23.040.80).

Key topics and requirements

• Scope: Material requirements specifically for cast polyurethane sealing elements intended for use in water and drainage pipe joints.
• Material focus: The standard addresses the properties and suitability of cast polyurethane as an elastomeric sealing material for potable water and wastewater systems (in context of pipe joint seals).
• Factory production control: Amendment A2 replaces Clause 6 with a clear requirement that the manufacturer shall establish and maintain an effective documented factory production control system. Factory production control must include continuous inspection performed by the manufacturer to ensure ongoing compliance with the standard.
• Normative references update: A2 removes references to EN ISO 9002 and EN ISO 9003 from the normative references, reflecting changes in referenced quality-system documents.
• Implementation: The amendment was approved by CEN on 14 July 2005 and was required to be adopted by CEN national bodies, with conflicting national standards withdrawn by February 2006.

Applications and who uses this standard

• Seal manufacturers: Use the standard to select, formulate and document cast polyurethane materials and to define production control processes for compliant seals.
• Product designers and system integrators: Reference EN 681-4 when specifying pipe joint seals for water distribution and drainage networks to ensure material suitability and regulatory alignment.
• Quality and compliance managers: Apply the factory production control requirements to maintain documented evidence of continuous inspection and product conformity.
• Procurement and specification writers: Incorporate the standard into tender and procurement documents for water/wastewater infrastructure components.
• Testing laboratories and certification bodies: Use the standard as a reference for material assessment and compliance verification.

Related standards

• EN 681 series (other parts cover different elastomeric materials and joint types) - consult the broader EN 681 family for complementary requirements and for seals made from other elastomers.
• CEN/TC 208 is the responsible technical committee for elastomeric seals for joints in pipework and pipelines.

By referencing EN 681-4:2000/A2:2005, stakeholders ensure cast polyurethane pipe joint seals meet harmonized European expectations for material suitability and that manufacturers implement continuous, documented factory production control.
