Overview
CEN/TS 1329-2:2026 is a technical specification published by the European Committee for Standardization (CEN), addressing plastics piping systems, specifically for soil and waste discharge applications within building structures using unplasticized poly(vinyl chloride) (PVC-U). Part 2 of this series focuses on the Assessment of Conformity, setting out comprehensive guidance and requirements for conformity assessment of formulations, products, and assemblies as specified in EN 1329-1:2026. This ensures products and systems meet required standards and are suitable for incorporation within manufacturers’ quality management systems and certification procedures. The specification supports improved quality, safety, and performance across the building and construction sector, facilitating compliance, durability, and functional efficiency for both low- and high-temperature waste discharge systems.
Key Topics
- Assessment of conformity (AoC): Guidance on how to evaluate whether PVC-U piping systems and associated products and assemblies meet the requirements of EN 1329-1:2026.
- Type testing (TT): Procedures for initial testing used to demonstrate that products, formulations, or assemblies conform to all relevant requirements. Type testing is mandatory when introducing new systems, materials, or designs.
- Batch release testing (BRT): Regular testing performed on each batch of product or material to ensure consistent quality before products are released into the market.
- Process verification testing (PVT): Ongoing checks to confirm that manufacturing processes consistently produce products that meet type test requirements.
- Audit testing (AT): Testing performed independently, often by or on behalf of certification bodies, to verify continued conformity and the effectiveness of the manufacturer’s quality management systems.
- Quality management integration: The requirements are designed to be incorporated into manufacturers’ existing quality management systems and quality plans, referencing ISO 9001 standards.
- Use of recyclate: Special provisions are included for systems using recycled materials, covering type testing, batch testing, and formulation tolerances.
- Certification procedures: Guidance for certification bodies operating under EN ISO/IEC 17065 and EN ISO/IEC 17020.
Applications
CEN/TS 1329-2:2026 is highly applicable to manufacturers, suppliers, and certification bodies dealing with PVC-U soil and waste discharge systems for buildings. Main uses include:
- Piping system production: Ensuring that pipes, fittings, and assemblies comply consistently with recognized product standards.
- Quality management implementation: As part of a wider quality system, supports traceability, process control, and product safety.
- Certification and market access: Provides a framework for third-party certification, supporting market entry and regulatory compliance across Europe and internationally.
- Product development and R&D: Assists in evaluating the impact of changes in material, formulation, or production method on conformity.
- Sustainability and circular economy: Supports the controlled use of recyclates and reworked materials in product formulations, enabling sustainable manufacturing practices without compromising product performance.
- Building and construction sector: Delivers confidence to specifiers, contractors, and end-users that products are suitable for a wide range of temperature and operational demands in residential, commercial, and industrial buildings.
