Thermoplastics pipes. Determination of resistance to external blows. Staircase method Ingestion-build-47182 The laboratory test methods inWhat is this standard about? This International Standard specifies a method for determining the resistance to external blows of thermoplastic pipes of circular Cross section; it is called the staircase method. This method is applicable to isolated batches of pipe to be tested at 0 C. NOTE 1 If testing below 0 C is necessary, the temperature of 20 C is recommended.
