Overview
EN ISO 13260:2011/A1:2017 (ISO 13260:2010/Amd.1:2017) is an amendment to the international test standard for thermoplastics piping systems for non‑pressure underground drainage and sewerage. The document defines a test method to assess the pipe system’s resistance to combined temperature cycling and external loading, helping manufacturers and testing laboratories verify long‑term performance under realistic thermal and mechanical stresses. This amendment was approved by CEN on 12 September 2017 and adopted as EN ISO 13260:2011/A1:2017.
Key topics and technical requirements
- Purpose: test method for the effect of temperature cycling combined with external loading on buried, non‑pressure thermoplastic sewer and drainage pipes.
- Amendment focus: revision of the tamping tool specification in Clause 4.9 to ensure consistent application of external loading during tests.
- Revised tamping tool requirements (explicit in Amendment 1):
- Overall mass: (10 ± 0.5) kg.
- Base surface: (300 ± 10) mm × (300 ± 10) mm.
- Facing: rubber at least 5 mm thick.
- Rubber hardness: nominally 60 IRHD, measured in accordance with ISO 48.
- Conformance: the amendment is an update to EN ISO 13260:2011; CEN members are required to incorporate it into national standards by the implementation deadline.
Applications and who uses this standard
- Manufacturers of thermoplastic pipes and fittings for buried, non‑pressure drainage and sewerage systems use this standard to validate product durability and resistance to combined thermal and mechanical effects.
- Independent testing laboratories apply the specified method and the updated tamping tool parameters to ensure repeatable, comparable test results.
- Specifiers and designers (civil engineers, infrastructure planners) reference test outcomes to select pipe systems suitable for environments with temperature fluctuations and expected external loading.
- Regulators and certification bodies use the standard as part of conformity assessment and product approval for non‑pressure underground sewage applications.
