Thermoplastics piping systems for non-pressure underground drainage and sewerage. Test method for resistance to combined temperature cycling and external loading1 Scope This International Standard specifies two methods for testing pipes and fittings or joints for plastics piping systems intended for use in underground drainage and sewerage systems for their resistance to deformation and leakage, when subjected to sustained external loading in conjunction with the passage of hot water. Method A involves temperature cycling, by passing hot water and cold water alternately, and is applicable to pipes and
