Overview
ISO 15877-5:2009/Amd 2:2020 is an international standard that specifies the fitness for purpose of chlorinated poly(vinyl chloride) (PVC-C) piping systems used for hot and cold water installations. This amendment updates key normative references and test parameters to ensure the reliability, performance, and safety of PVC-C piping systems under various operational conditions. As part of the ISO 15877 series, this document focuses specifically on system suitability, addressing the combined performance of pipes, fittings, and joints to meet durable water supply infrastructure requirements.
This standard plays a critical role in guiding manufacturers, installers, and quality assessors in evaluating PVC-C piping systems in compliance with global best practices and technical regulations.
Key Topics
-
Scope and Purpose
Focuses on assessing the overall fitness for purpose of PVC-C piping systems, considering mechanical strength, thermal resistance, and leak-tightness for hot and cold water applications.
-
Updated Normative References
The amendment replaces previous European Norm (EN) standards with corresponding ISO standards, such as:
- ISO 3501 for mechanical joint resistance to pull-out
- ISO 19893 for resistance to temperature cycling
- ISO 13056 for vacuum leaktightness testing
- ISO 19892 for resistance of joints to pressure cycling
-
Thermal Cycling Test Parameters
Revised conditions specify testing under multiple temperature cycles (range: 20°C to up to 95°C), with durations adjusted based on pipe diameter and application class. This ensures material resilience against thermal stresses encountered in real-world installations.
-
Pressure Cycling Requirements
Defines comprehensive procedures and pressure limits for testing joints and assemblies, including:
- Minimum cycles (up to 10,000 for smaller diameters)
- Varied test pressures corresponding to design pressure classes (4 to 10 bar)
- Leak-tightness criteria at ambient temperature
-
Test Setup and Assembly Configurations
Establishes requirements for number of fittings, pipe lengths, and test piece preparations to provide representative validation of piping systems.
Applications
-
Hot and Cold Water Plumbing Installations
Used extensively in residential, commercial, and industrial buildings for safe and efficient water distribution.
-
Manufacturing Quality Assurance
Enables producers of PVC-C pipes, fittings, and valves to certify their products meet necessary international performance benchmarks.
-
Installation Verification
Assists installers and inspectors in confirming system compliance with pressure, temperature, and joint integrity standards.
-
Maintenance and System Longevity
Provides criteria for evaluating aging piping systems, facilitating preventative maintenance and replacement planning to avoid failures.
