Significance and Use
This practice is intended to provide a list of standard procedures for test programs investigating the chemical resistance of a geogrid to a liquid. This practice should be used in the absence of other specifications required for the particular situation being addressed.
This practice is intended to provide a basis of standardization for those wishing to compare or investigate the chemical resistance of a geogrid. It should be recognized that chemical resistance is a user judgment evaluation and that this practice does not offer procedures for interpreting the results obtained from test procedures contained in this practice. As a practice, this does not produce a test result.
This practice is for the chemical resistance assessment of geogrids and is written in parallel to similar practices for geomembranes, geotextiles, geonets, and geopipes. Each practice is to be considered individually for the geosynthetic under investigation and collectively for all geosynthetics exposed to the potentially harsh chemical environment under consideration.
1.1 This practice covers the procedures for testing of geogrids for chemical resistance to liquids.
1.2 This practice describes methods for measuring changes in physical and mechanical properties caused by immersion in test solutions that may be representative of anticipated end-use conditions.
1.3 This practice describes procedures for required and recommended testing of geogrids.
1.4 Evaluation or interpretation of test data is beyond the scope of this practice.
1.5 This practice is intended to be used in conjunction with D 5322
1.6 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. Specific precautionary statements are given in Section 7.
