This Standard specifies a method for determining the resistance to external blows of thermoplastics pipes with circular cross sections by using the round-the-clock method. The method is intended to be applied to isolated batches of pipe. For type testing and audit testing, 0 °C and/or -20 °C are applicable. Annex A, which is informative, gives guidance on evaluation of results and sampling from a running production.
