ASTM D6241-22

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

SIGNIFICANCE AND USE
5.1 Puncture using a 50 mm flat circular probe is applicable to determine the index strength resistance and deformation of a particular geotextile or geotextile-related products.  
5.2 This test method is considered satisfactory for acceptance testing of commercial shipments of geotextiles.  
5.3 In case of a dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and that are from a lot of the type in question. The test specimens then should be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student's t-test for unpaired data and an acceptable probability level chosen by the two parties before the testing is begun. If a bias is found, either its cause must be found and corrected, or the purchaser and the supplier must agree to interpret future test results in light of the known bias.  
5.4 This test method is not applicable to materials that are manufactured in sizes that are too small to be placed into the test apparatus in accordance with the procedures in this test method. Furthermore, it is not appropriate to separate plies of a geosynthetic or geocomposite for use in this test method.
SCOPE
1.1 This test method is an index test used to measure the force required to puncture a geotextile and geotextile-related products with a 50 mm diameter probe rod. The dimensions of the probe provide a multidirectional force on the geotextile.  
1.2 The values stated in SI units are to be regarded as the standard. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4. Summary of Test Method
4.1 A test specimen is clamped without tension between circular plates and secured in a tensile or compression testing machine,
or both. A force is exerted against the center of the unsupported portion of the test specimen by a circular steel plungerprobe
attached to the load indicator until rupture occurs. The maximum force is the value of puncture strength.
5. Significance and Use
