Phạm vi áp dụng / Scope of standard

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

1.2 The use of Test Method D4833/D4833M may be inappropriate for testing some woven geotextiles or related products which have large openings, such as geonets and geogrids.

1.3 It is recommended that geotextile and geotextile related products be tested using Test Method D6241.

1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
