Thermoplastics pipes. Determination of resistance to external blows. Round-the-clock method Ingestion-build-201039 Air filters for passenger compartmentsWhat is this standard about? This International Standard specifies a method for the determination of the resistance to extemal blows of thermoplastics pipes of circular Cross section; it is called the round the clock method. This method is applicable to isolated batches of pipe tested at 0 C (information is also given for sampling from the continuous production of Pipe). NOTE 1 If testing below 0 C is required, a temperature of 20 C is recommended.
