Overview

EN 13476-2:2018/prA1 is a European standard developed by CEN for plastics piping systems used in non-pressure underground drainage and sewerage applications. Specifically, it covers structured-wall piping systems made from unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), and polyethylene (PE). This part 2 of the EN 13476 series defines the specifications for pipes and fittings characterized by smooth internal and external surfaces, classified as Type A.

The standard applies to structured-wall pipes and fittings intended for underground installation outside buildings ("U" marking) and for systems buried both outside and inside buildings ("UD" marking). It includes requirements for pipes and fittings with or without integral sockets featuring elastomeric ring seal joints, as well as welded and fused joints. EN 13476-2:2018/prA1 outlines test methods, parameters, size ranges, materials, stiffness classes, application classes, tolerance classes, and provides recommendations regarding product color coding.

This standard assists specifiers, designers, manufacturers, and installers in selecting appropriate piping systems compliant with European regulations and technical guidelines for durable, reliable underground drainage infrastructure.

Key Topics

• Material Types: Unplasticized PVC (PVC-U), polypropylene (PP), polyethylene (PE) structured-wall piping.
• Surface Characteristics: Smooth internal and external surfaces for optimized flow and corrosion resistance.
• Piping and Fittings: Standards for pipes and injection-moulded or fabricated fittings, including socket and joint types.
• Application Zones: Markings "U" (underground outside building) and "UD" (underground inside and outside the building) signify suitable use areas.
• Testing Requirements: Defined sampling frequencies from material batches and detailed test methods ensure consistent product quality.
• Use of Reprocessed Material: Permits the use of clean reprocessed materials in pipe and fitting production without limitations.
• Mechanical and Dimensional Properties: Stiffness, tolerance, and application classes tailored to specific installation conditions.
• Marking and Identification: Guidelines for clear product identification through codes and color recommendations.

Applications

EN 13476-2:2018/prA1 piping systems are designed for critical underground drainage and sewerage networks operating under gravity flow rather than pressure. Typical practical applications include:

• Municipal underground sewer and drainage infrastructure.
• Residential and commercial building drainage systems buried in soil.
• Stormwater management and wastewater disposal piping.
• Replacement and rehabilitation of existing underground pipelines with high corrosion and abrasion resistance.
• Installation in regions with stringent regulatory requirements on piping materials and installation methods.

These pipes and fittings help infrastructure stakeholders achieve long service life, environmental safety, and system integrity in underground waste water conveyance.

Related Standards

• EN 13476-1 - General requirements, system design, and definitions for structured-wall piping systems.
• EN 13476-3 - Specifications for pipes and fittings with profiled internal and external surfaces (Type B).
• EN ISO 9001 - Quality management systems relevant to manufacturing processes.
• National and regional building codes and installation standards complementing these piping system specifications.
• Other CEN/TC 155 standards covering plastic piping systems and drainage solutions.

By adhering to EN 13476-2:2018/prA1, manufacturers and specifiers ensure compliance with harmonized European criteria, promoting interoperability, safety, and high performance in underground non-pressure drainage solutions.
