Notch Milling Machine for SCG Tester (NPT, ANPT Test)-250mm

ACCELERATED NOTCH PIPE TEST (ANPT)
Test method and equipment
The notch pipe test (NPT) is a well-known and much used test method. The first version of the standard (ISO 13479) was published in 1997. The method published by Kratochvilla et al [13,19] attracted new interest [15] in the search for new methods to test PE 100-RC pipes. The aNPT is very similar to the standard NPT, but with one important difference: to reduce the time to failure, an external detergent solution is used in contact with the notches instead of water. An annex to ISO/TC138/SC5/WG20 containing more details about the test method is currently being drafted. For now, the aNPT is performed with only 2% Arkopal N100.
