Standard Test Method for Effects of Temperature on Stability of Geotextiles

SIGNIFICANCE AND USE
5.1 This test method is used for evaluating the relative effects of temperature on geotextiles manufactured from different polymers, by a different manufacturing process, or both.  
5.2 During shipping and storage, the geotextile may be exposed to abnormal temperatures. The fabric could be tested at these temperatures to determine the detrimental effects of these conditions on the strength properties.  
5.3 This test method may also be used to evaluate the cyclic effects of temperature (freeze-thaw), that is, samples can be conditioned to below normal temperatures (below freezing) and then to above normal temperatures (elevated temperatures) for a given number of cycles. Strength characteristics can be determined after these cyclic exposures.  
5.4 Most nonwoven, woven, and composite fabric can be tested by this method. Modification of the techniques is likely to be necessary for any fabric having a strength in excess of 179 kg/cm [1000 lb/in.] width. This test method is not recommended for knitted fabrics.  
5.5 This test method is an index test method and is not recommended for acceptance testing of commercial shipments, since information on between laboratory precision has not been established. In some cases the purchaser and seller may have to test a commercial shipment of one or more geotextiles by the best available method, even though the method has not been recommended for acceptance testing of commercial shipments. A comparative test performed as directed in 5.5.1 may be advisable.  
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 possibl...
SCOPE
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.

Test Method D5035. The same tests are conducted as control under the standard laboratory test conditions. Tensile strength and
percent elongation properties obtained at various test temperatures are recorded. Changes in strength characteristics due to the
effects of temperature are determined.
4.2 The temperatures used for conditioning and testing the geotextiles are the temperatures at which the geotextile will perform
or are typically exposed to in the field.
5. Significance and Use
5.1 This test method is used for evaluating the relative effects of temperature on geotextiles manufactured from different
polymers, by a different manufacturing process, or both.
5.2 During shipping and storage, the geotextile may be exposed to abnormal temperatures. The fabric could be tested at these
temperatures to determine the detrimental effects of these conditions on the strength properties.
5.3 This test method may also be used to evaluate the cyclic effects of temperature (freeze-thaw), that is, samples can be
conditioned to below normal temperatures (below freezing) and then to above normal temperatures (elevated temperatures) for a
given number of cycles. Strength characteristics can be determined after these cyclic exposures.
5.4 Most nonwoven, woven, and composite fabric can be tested by this method. Modification of the techniques is likely to be
necessary for any fabric having a strength in excess of 179 kg/cm (1000 lb/in.)[1000 lb/in.] width. This test method is not
recommended for knitted fabrics.
5.5 This test method is an index test method and is not recommended for acceptance testing of commercial shipments, since
information on between laboratory precision has not been established. In some cases the purchaser and seller may have to test a
commercial shipment of one or more geotextiles by the best available method, even though the method has not been recommended
for acceptance testing of commercial shipments. A comparative test performed as directed in 5.5.1 may be advisable.
5.5.1 In case of a dispute arising from differences in reported test results when using Test Method D4594D4594/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 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.
