Standard Test Method for Deterioration of Geotextiles from Outdoor Exposure

Importancia y uso:

5.1 Outdoor exposure tests at one location may not be applicable to a project site at another location. This test method evaluates geotextiles under site-specific atmospheric conditions over an 18-month period. A degradation curve as per 10.8, based on strength, elongation, or modulus, or all of these, may be developed for the geotextile being evaluated.

5.2 This test method can be used for comparative testing of the degradation of geotextiles.

5.3 This test method is considered to be a performance test and as such the responsibility for its performance rests with the specifying or purchasing agency.

Note 1: The intent of this procedure is to provide the user of this test method and geotextiles a standard by which to evaluate weathering degradation in terms of site-specific conditions, not in terms of incident radiation and temperature. If desired, the user may want to have the necessary measurement and recording equipment at each site to do this. However, the expense of doing so at each site may be prohibitive. Therefore, this is not a specific requirement of this test method.
