英文名称：Thermoplastics piping systems for non-pressure applications — Test method for resistance to elevated temperature cycling
发布日期：2018-11
标准范围
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.
