EN ISO 13433 - DYNAMIC PERFORATION TEST (CONE DROP TEST)


With this test it is possible to evaluate the mechanical resistance of geotextiles to the impact of stone aggregates, during the phase of covering with filling material on site.

Test procedure: a steel cone with a weight of 1000 g is dropped from a height of 500 mm on a sample of geotextile, fixed between 2 rings with internal diameter 150 mm.

At the end of the procedure is measured the diameter of hole in the geotextile, using a standard graduated cone.
