Overview

prEN 15014 is a European Standard developed by CEN that sets out specifications for plastics piping systems designed for buried and above-ground pressure applications. It focuses on pipes and fittings used for water supply, drainage, sewerage, and irrigation systems, excluding water intended for human consumption. This standard provides detailed requirements and test/assessment methods for product characteristics such as pressure resistance, dimensional tolerances, tightness, durability, and release of substances.

This standard complements other relevant regulations and standards and excludes components like valves, adhesives, joint sealings, and gaskets. While products that comply with prEN 15014 may be used for transporting potable or raw water under specific national or regional regulatory provisions, this compliance alone does not guarantee fitness for potable water transport per Regulation (EU) No. 305/2011 (CPR).

Key Topics

• Product Characteristics

  • Internal and external pressure strength of pipes and fittings
  • Dimensional tolerances
  • Liquid tightness of pipes, fittings, and connections
