CSN EN ISO 13257

CSN EN ISO 13257 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.
