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 O C are applicable. NOTE: Pipes made f rom polypropyl ene homopolymer (PP- W) whi ch principally can not confonn to impact requirements at 0 C or lower temperatures are permitted to be tested at (23 j: 2) OC under the condition that PP-H pipes are intended for use for soil and waste discharge and bear an additional marking indicating that they are not to be installed below +5 OC.
