Significance and Use
5.1 This practice is intended to provide a list of standard procedures for test programs for investigating the chemical resistance of a geonet with a liquid waste, leachate, or chemical. This practice should be used in the absence of other specifications required for the particular situation being addressed.
5.2 Chemical resistance, as used in this practice, is not a quantifiable term. This practice is intended to provide a basis of standardization for those wishing to compare or investigate the chemical resistance of a geonet. 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 herein. As a practice, a test result is not produced.
5.3 This practice is for the chemical resistance assessment of geonets and is written in parallel to similar practices for geomembranes, geogrids, geotextiles, 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 describes procedures for testing geonet products for chemical resistance with liquid wastes, prepared chemical solutions, or leachates, or both, derived from solid wastes.
1.2 This practice describes test methods for measuring changes in mass, dimensions, tensile and hydraulic properties and other optional physical and mechanical properties caused by immersion in test solutions, which may be representative of anticipated end use conditions. This practice may be used to assess the extent to which a product's as-manufactured properties are affected by such immersion.
1.3 This practice is intended to be used in conjunction with Practices D5322 or D5496. The scope of this practice is limited to testing and reporting procedures for unexposed and exposed geonet samples.
1.4 Evaluation or interpretation of test data is beyond the scope of this practice.
1.5 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 Section 7 for specific hazards statements.
