The resistance of pipes with external point loads to slow crack growth can be determined by means of a point load test. Over the last 50 years, polyethylene (PE) has developed into an extremely high performance raw material. Significant advances have been made over the last few years in optimising PE's susceptibility to stress cracking, particularly with regard to pressure pipes. Pipes with PE 100-RC (resistant to crack) qualities are suitable for alternative installation techniques (trenchless and sand bed-free installation).

The point load test in accordance with PAS 1075 represents a key test method for ensuring the quality of materials and pipes. The point load test on the pipe simulates an installation situation in which the pipe is disturbed by the external influence of a point load, such as stones or sharp-cornered objects. The test procedure is similar to the internal pressure creep test, with the difference being that an external point load (generally a punch) is also applied before the internal pressure. To accelerate the test further, a wetting agent solution is applied to the test sample.

In addition to touch control, our new point load tester includes integrated pressure generation from 1 to 12 bar as well as automatic failure detection and heated storage tanks (approx. 15 l) with stirrer as a reservoir for topping up the wetting agent solution.
