Thermoplastics pipes for the transport of fluids-Determination of impact by the charpy method
Ⅰ. Use:
Used to test the anti-impact property of thermoplastic pipes,engineering plastics.glass,pottery,cast stone and other non-metallic materials.
Ⅱ. Principle:
A small section of pipe or machined gap-free strip specimen was preprocessed at the specified test temperature.The sample is then supported in the horizontal direction, with a quick impact at the support line with a swing hammer with a given impact energy.After an impact on the specified number of samples, the test results are identified as the percentage of the number of sample damages against the total number of samples tested.
