ISO 3127
Thermoplastics pipes -- Determination of resistance to external blows -- Round-the-clock method

ISO3127 Standard specifies a method for the determination of the resistance to external 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).

Test pieces are subjected to blows from a falling striker, of specified mass and shape, dropped from a known height onto specified positions around the circumference of the test piece. The true impact rate of the batch, or production run from an extruder, is estimated.

Commonly the impact height 2000mm, impact hammer 6.3kg, 9.1kg, 13.6kg.
