ASTM D4594/D4594M-96(2015)e1

5.5.1 In case of a dispute arising from differences in reported test results when using Test Method D4594/D4594M 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 homogenous as possible and that are from a lot of 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's 1.1 This test method provides a procedure for determining the effects of climatic temperature on the tensile strength and elongation properties of geotextiles.

1.2 The effect of temperature on the stability of geotextiles is reported as the change in tensile strength and elongation between tests performed as directed in Test Method D5035, in the standard atmosphere for testing textiles, and tests performed under conditions at which the geotextile is expected to perform in the field.

1.3 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.

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. See 7.1.1 – 7.1.3.
