ASTM D6241-99

Standard Test Method for the Static Puncture Strength of Geotextiles and Geotextile-Related Products Using a 50-mm Probe

SCOPE
1.1 This test method is an index test used to measure the force required to puncture a geotextile and geotextile related products. The relatively large size of the plunger provides a multidirectional force on the geotextile.
1.2 The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
