Significance and Use:

This test method is an index test for determining the puncture resistance of geotextiles, geomembranes, and related products. The use of this test method is to establish an index value by providing standard criteria and a basis for uniform reporting.

This test method is considered satisfactory for acceptance testing of commercial shipments of geotextiles, geomembranes, and related materials since the test method has been used extensively in the trade for acceptance testing.

5.2.1 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 material of the type in question. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student’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 the light of the known bias.

Scope:

1.1 This test method is used to measure the index puncture resistance of geotextiles, geomembranes, and related products.

1.2 The use of Test Method D 4833 may be inappropriate for testing some woven geotextiles or related products which have large openings (Note 1).

Note 1—Geonets and geogrids cannot be tested using this test method.

1.3 The values stated in SI units are to be regarded as the standard. The values provided in inch-pound units are for information only.

1.4 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.
