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

It 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.

ISO 3127 Plastics Pipe falling weight impact test

Unitedtest ISO 3127 Plastic/PVC pipe falling hammer impact testing equipment is used to determine the energy required to break or rupture test specimens such as pipe, sheet, laminates, composites, ceramics, and nonferrous metals for material and component evaluation to international testing methods such as ISO6603, ISO3127, ASTMD2444, and UL 651 to name a few.

Round the Clock Method – Lengths of pipe from a batch or production run are subjected to blows from a known mass that falls from a specified height as per test standards ISO3127 & EN744.

Staircase Method – Lengths of pipe are subjected to blows from a known mass and shape but is dropped from differing heights depending on the results of each blow as per test standard EN1411.

ISO 3127 Plastics Pipe falling weight impact test

1, Automatic falling hammer impact tester adopt micro processor control, avoid secondary impact, can preset impact height, automatically hang the hammer, automatically lift hammer to set height position etc.,
