Overview
EN ISO 15877-5:2009/A2:2020 is Amendment 2 to Part 5 of ISO 15877, the European/ISO standard for plastics piping systems for hot and cold water installations made from chlorinated poly(vinyl chloride) (PVC‑C). This amendment updates normative references and test parameters used to demonstrate the fitness for purpose of the system. The amendment was approved by CEN on 12 October 2020 and integrated into national standards by mid‑2021.
Key topics and requirements
- Updated normative references - several EN references are replaced by ISO standards:
- EN 712 → ISO 3501 (pull‑out resistance test for mechanical joints)
- EN 12293 → ISO 19893 (thermal cycling test for mounted assemblies)
- EN 12294 → ISO 13056 (leaktightness under vacuum)
- EN 12295 → ISO 19892 (pressure cycling)
- Thermal cycling parameters for PVC‑C assemblies:
- Defines maximum design and highest/lowest test temperatures per application class (examples: highest test temperature up to 95 °C, lowest 20 °C).
- Specifies cycle durations (e.g., 15 min at high + 15 min at low = 30 min; or 150 + 150 = 300 min) and cycle counts (typically 5 000 cycles for diameters ≤160 mm; 500 cycles for >160 mm).
- Requires representative assembly configurations and minimum free pipe lengths between joints.
- Pressure cycling parameters (ISO 19892):
- Test temperature: 23 °C; no leakage permitted.
- Frequencies: ~30 ±5 cycles/min (d ≤160 mm) and ~15 ±3 cycles/min (d >160 mm).
- Cycle counts: 10 000 (d ≤160 mm) and 5 000 (d >160 mm).
- Test pressure limits tied to design pressure (e.g., for 4 bar design: upper 6.0 bar / lower 0.5 bar; for 10 bar design: upper 15.0 bar / lower 0.5 bar).
Applications and users
This amendment is essential for:
- Manufacturers of PVC‑C pipes, fittings and joint systems - for type testing and product validation.
- Test laboratories - to perform thermal cycling, pressure cycling, pull‑out and vacuum tests to the updated methods.
- Specifiers, consultants and installers - for selecting compliant PVC‑C systems for hot/cold water and sanitary installations.
- Regulators and certification bodies - to assess conformity and system fitness for purpose in potable and non‑potable water supply applications.
