ISO 13433:2006规定了一种测定土工合成材料抗从固定高度掉落的钢锥穿透的方法。当尖锐的石块落在土工合成材料表面时，渗透程度是土工合成材料性能的指标。 该方法通常适用于土工合成材料。然而，由于测试原则可能不适用，因此应仔细考虑该测试对某些类型产品的有效性。

ISO 13433:2006 specifies a method to determine the resistance of geosynthetics to penetration by a steel cone dropped from a fixed height. The degree of penetration is an indication of the behaviour of the geosynthetic when sharp stones are dropped on its surface. The method is generally applicable to geosynthetics. However, the validity of this test for some types of products should be considered carefully, as the test principle may not be applicable.
