This document specifies a test method for determining the resistance to elevated temperature cycling of thermoplastics piping systems for non‑pressure applications, inside buildings or buried in the ground within the building structure. This document is applicable to piping systems with components of nominal outside diameters up to and including 200 mm. Although limited to nominal outside diameters up to and including 200 mm, the test results may be extrapolated to products of larger nominal outside diameters from the same range.
Abstract
Overview
EN ISO 13257:2018 (Thermoplastics piping systems for non-pressure applications - Test method for resistance to elevated temperature cycling) is a CEN-endorsed ISO test method that specifies how to evaluate the ability of thermoplastic drainage and soil piping systems to withstand repeated temperature extremes. The standard applies to systems used inside buildings or buried in the ground within the building structure and covers components with nominal outside diameters up to and including 200 mm (with results potentially extrapolatable to larger diameters).
Key topics and technical requirements
- Test principle: subject a representative test assembly of pipes and fittings to repeated cycles of hot and cold water and verify joint leak tightness and dimensional changes (sagging) after cycling.
- Scope limits: intended for non-pressure applications (gravity drainage, soil and waste) and components up to DN/OD 200 mm.
- Test assemblies: defined configurations for components with integral sockets and for components without sockets, with specific layouts for vertical and adjacent horizontal branches (different arrangements for d ≥ 40 mm and d
