Overview

EN 1329-1:2020 is the CEN European standard that specifies requirements for PVC‑U (unplasticized polyvinyl chloride) plastics piping systems used for soil and waste discharge (low and high temperature) within the building structure. It covers solid‑wall pipes with smooth internal and external surfaces, fittings and the complete system for use either:

• Inside buildings (application area code B), and
• Inside buildings and buried in ground within the building structure (application area code BD; components for buried use are for nominal outside diameters ≥ 75 mm).

The document also defines test parameters for referenced test methods and gives recommendations on sizes, series and colours. It aligns with other product standards listed in Annex B and supersedes EN 1329‑1:2014+A1:2018.

Key Topics

• Material requirements: PVC‑U formulations for pipes and fittings, allowances for mineral modifiers and limited use of non‑virgin material (see Annex A).
• Geometrical characteristics: outside diameter, wall thickness, out‑of‑roundness, socket and spigot dimensions and joint geometry to ensure system compatibility.
• Mechanical & physical properties: impact resistance, resistance to internal pressure (test parameters referenced to EN ISO methods), and additional mechanical tests for fittings.
• Performance requirements: system performance for soil, waste and ventilating branches as well as internal rainwater systems.
• Sealing rings & adhesives: specifications for elastomeric seals and adhesive joints used in non‑pressure piping.
• Marking & identification: product marking including application code (“B” or “BD”), material identification and traceability.
• Reaction to fire: provisions added in the 2020 revision.
• Normative references: cross‑references to EN 1401‑1, EN 476, EN 681, EN 14680 and other EN/ISO test standards.

Applications

EN 1329‑1:2020 is intended for:

• Manufacturers designing and producing PVC‑U pipes and fittings for soil, waste and rainwater drainage inside buildings.
• Specifiers and purchasers (consultants, architects, MEP engineers) for selecting compliant systems and confirming suitability for “B” or “BD” applications.
• Installers and contractors relying on standardized joint dimensions and performance requirements for proper installation.
• Test laboratories and conformity bodies applying the referenced test methods and marking requirements.

Practical uses include internal soil stacks, branch drainage, ventilating sections of wastewater systems and internal rainwater downpipes where PVC‑U benefits (chemical resistance, ease of installation) are required.

Related Standards

• EN 1401‑1 (PVC‑U for non‑pressure underground drainage)
• EN 1453‑1 (multilayer/foamed pipes – excluded from EN 1329‑1)
• EN 476 (general requirements for discharge components)
• EN 681 series (elastomeric seals)
• EN 14680 / EN 14814 (adhesives for thermoplastic piping)
