Overview
EN ISO 13846:2000 - Plastics piping systems - defines a test method for long-term leaktightness under internal water pressure for mechanically joined thermoplastics pressure piping. The standard covers both end-load-bearing and non-end-load-bearing assemblies and joints between fittings, ancillaries, valves and thermoplastic pipes (including integral pipe joints). It applies to connections of similar or dissimilar materials and to sealing systems using elastomeric sealing rings or adhesives. EN ISO 13846:2000 is the European adoption of ISO 13846:2000 and is used to evaluate sustained watertight performance of joints in pressurized plastic pipeline systems.
Key Topics
- Scope of test method: Defines the purpose and applicability for long-term leaktightness assessment under internal water pressure for mechanically joined assemblies and joints.
- Joint types covered: End-load-bearing and non-end-load-bearing mechanical joints, including integral pipe joints and assemblies with fittings, valves and ancillaries.
- Material combinations: Applicable to joints joining similar or different thermoplastic materials.
- Sealing mechanisms: Includes joints using elastomeric sealing rings and adhesive-bonded seals.
- Performance focus: Long-term resistance to internal water pressure and prevention of leakage over an extended service life.
- Test reproducibility and comparability: Provides a standardized procedure for laboratories and manufacturers to compare joint performance reliably.
Applications
EN ISO 13846:2000 is practical for:
- Manufacturers of thermoplastic pipes, fittings and valves - to validate product joint performance and support product declarations.
- Independent testing laboratories - to perform standardized long-term leaktightness tests for certification and quality assurance.
- Engineers and specifiers - to select joint types and sealing systems suitable for pressurized water distribution, potable water, wastewater and industrial fluid systems.
- Installers and contractors - to understand expected long-term joint behavior and compliance requirements.
- R&D teams - to compare sealing materials, joint designs and adhesive systems for durability under internal pressure.
Related Standards
- EN ISO 13846:2000 is identical to ISO 13846:2000 and typically used alongside other EN/ISO product and installation standards for thermoplastic piping systems (e.g., standards covering PE, PP piping products and installation practices). Consult relevant product-specific standards when applying EN ISO 13846:2000 in certification or design work.
