Overview
EN ISO 15874-2:2013/A1:2018 is an essential European standard focusing on plastics piping systems for hot and cold water installations, specifically addressing polypropylene (PP) pipes. This document is an amendment to EN ISO 15874-2:2013, introduced to refine and expand the technical specifications related to the dimensions and tolerances of polypropylene pipes used within water supply systems.
Prepared by the collaboration of ISO Technical Committee ISO/TC 138 and CEN Technical Committee CEN/TC 155, this amendment ensures harmonized requirements across CEN member countries. It aligns material standards for polypropylene piping, facilitating the consistent quality, safety, and performance of piping systems essential for both domestic and commercial hot and cold water installations.
Key Topics
-
Scope Extension: Inclusion of larger pipe dimensions ranging from 180 mm to 250 mm, expanding the applicability of polypropylene pipes in larger water supply systems.
-
Pipe Dimensions: Detailed specifications on nominal diameter, mean outside diameter, and a comprehensive series of wall thickness options within dimension class A, carefully categorized by pipe series ranging from S 8 to S 2.
-
Tolerance Requirements: Updated tolerance limits on wall thickness of pipes, ensuring precision manufacturing, durability, and conformity with Grade A tolerance levels as per ISO 11922-1 standards.
-
Material Focus: Concentration on PP-RCT (Polypropylene Random Copolymer with Modified Crystalline Structure), which is known for advanced thermal and mechanical properties suitable for pressure piping systems in water installations.
-
Standardization and Compliance: Clear guidance for CEN national bodies to incorporate this amendment as part of their national standards without alterations, ensuring uniformity across Europe.
Applications
EN ISO 15874-2:2013/A1:2018 applies primarily to:
- Installation of hot water distribution systems in residential, commercial, and industrial buildings where polypropylene piping is preferred due to corrosion resistance and chemical inertness.
- Cold water supply systems within municipal infrastructure and private water networks demanding standardized, high-quality plastic piping.
- Systems requiring pressure-rated polypropylene pipes with reliable mechanical performance and longevity.
- Scenarios where precise manufacturing tolerances are vital to guarantee pipe fitting compatibility, ease of installation, and maintenance efficiency.
This amendment supports engineers, manufacturers, and suppliers by providing reliable dimensions and material specifications critical to the design and installation of safe, durable plumbing solutions.
