ISO 15874-1:2013/Amd 1:2022

Overview

ISO 15874-1:2013/Amd 1:2022 is an important amendment to the international standard covering plastics piping systems specifically designed for hot and cold water installations made from polypropylene (PP). This amendment incorporates a critical update regarding the impact test for polypropylene materials used in piping components. Developed by ISO Technical Committee ISO/TC 138 and in cooperation with CEN/TC 155, this standard ensures enhanced safety, material performance, and reliability of PP piping systems in water supply applications.

The amendment focuses on the material characteristics of polypropylene by specifying additional impact resistance requirements consistent with ISO 179-1 testing methods. As such, ISO 15874-1:2013/Amd 1:2022 provides vital guidance for manufacturers, engineers, and quality professionals involved in plastics piping system design, production, and quality control.

Key Topics

• Scope Update: Amendment 1 introduces the mandatory Charpy impact test as per ISO 179-1, targeting improved mechanical resilience of polypropylene piping components.
• Material Characteristics: The amendment defines minimum impact resistance values for PP materials used in hot and cold water systems. It specifies:
  • A minimum Charpy impact resistance of ≥ 4 kJ/m² at 0°C for notched test specimens.
  • Applicability to PP materials after 7 days post-injection or machining.
  • Exception for PP-H (homopolymer polypropylene) materials which are exempt from this impact resistance requirement.
• Test Methodology: The impact test must be conducted following the ISO 179-1/1eA standard approach using notched specimens to simulate real-world stress conditions.
• Quality Assurance: This amendment strengthens the quality and durability criteria for polypropylene piping products, reducing the risk of failure due to impact stresses during installation or service.

Applications

ISO 15874-1:2013/Amd 1:2022 is essential for stakeholders in the construction, plumbing, and water infrastructure sectors, especially where plastic piping systems are used for potable hot and cold water:

• Manufacturers: To ensure product compliance by integrating the specified impact test in quality control protocols, improving polymer selection and processing conditions.
• Engineers/Designers: To ensure the selected polypropylene piping systems meet updated performance standards for impact resistance, contributing to more durable and secure water installation systems.
• Specifiers and Regulators: To reference updated standards ensuring safety and reliability in building codes and procurement specifications.
• Installation Professionals: To understand material properties and ensure compatibility with system requirements, particularly in environments subjected to mechanical shocks or stresses.

This amendment supports safer and longer-lasting polypropylene piping systems, widely used in residential, commercial, and industrial water supply networks.
