Overview

ISO 22391-5:2009/Amd 1:2020 is an important amendment to the international standard governing plastics piping systems used for hot and cold water installations. Specifically, this standard focuses on Polyethylene of Raised Temperature resistance (PE-RT) and addresses the fitness for purpose of the entire piping system. The amendment, published in 2020 and corrected in 2021, updates technical references and test parameters to ensure enhanced system reliability and safety under operational conditions.

Developed by ISO Technical Committee ISO/TC 138 in collaboration with the European Committee for Standardization (CEN/TC 155), this standard aligns testing methods and requirements for PE-RT piping systems with evolving industry practices, providing critical guidance for manufacturers, installers, and regulatory authorities engaged in water supply infrastructure.

Key Topics

  • Scope of PE-RT Piping Systems
    Covers hot and cold water installations utilizing PE-RT materials, designed to withstand high temperatures and pressure cycling. Ensures the complete system’s hygienic and mechanical fitness.

  • Updated Normative References
    This amendment revises several referenced standards to ISO equivalents to unify test methods, including:

    • ISO 3501 (Mechanical joints pull-out resistance)
    • ISO 3503 (Leaktightness under bending)
    • ISO 19893 (Resistance to temperature cycling)
    • ISO 13056 (Leaktightness under vacuum)
    • ISO 19892 (Resistance to pressure cycling)
  • Thermal Cycling Test Parameters
    The amendment specifies updated parameters for testing thermal cycling resistance based on application classes, maximum design temperatures (70°C to 90°C), test durations, and cycle counts to simulate real-world temperature swings and stress.

  • Pressure Cycling and Leakage Testing
    Details test pressures, cycle frequencies, and leak detection requirements for pipes with different diameters to ensure system integrity over prolonged pressurized use.

  • System Fitness for Purpose
    Focuses on evaluating the entire piping assembly-not only individual components-ensuring compatibility, durability, and safety under specified operating conditions.

Applications

ISO 22391-5:2009/Amd 1:2020 is essential for:

  • Water Supply Piping Systems
    Ensures plumbing installations in residential, commercial, and industrial environments meet rigorous performance and safety criteria.

  • Hot and Cold Water Distribution
    Supports infrastructure for potable water by confirming PE-RT piping can reliably withstand temperature variations and pressure fluctuations.

  • Building and Construction Industry
    Guides manufacturers, contractors, and engineers in selecting and deploying PE-RT pipes that comply with international safety and quality benchmarks.

  • Quality Assurance and Certification
    Supports conformity assessment bodies in testing system performance to validate compliance with updated technical requirements.

Related Standards

  • ISO 22391 Series
    The broader series covering plastics piping systems for water installations with PE-RT materials, which addresses design, testing, and installation guidelines.

  • ISO 3501, ISO 3503, ISO 19893, ISO 19892, ISO 13056
    Referenced standards providing test methods critical for mechanical joint strength, leaktightness, and resistance to temperature and pressure cycling.

  • ISO/IEC Directives, Part 1 and 2
    Guidance documents on developing and maintaining ISO standards, ensuring consistency and clarity across technical publications.
