Description

Significance and Use

This practice is intended to provide a list of standard procedures for test programs investigating the chemical resistance of a geomembrane 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.

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 geomembrane. It should be recognized that chemical resistance is a user judgement 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.

Note 2—This practice is for the chemical resistance assessment of geomembranes and is written in parallel to similar standard practices for geotextiles, geonets, geogrids, geopipes, and geosynthetic clay liners. Each standard 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. Scope

1.1 This practice covers procedures for the testing of geomembranes for chemical resistance with liquid wastes, prepared chemical solutions, and leachates derived from solid wastes.

1.2 This practice covers procedures for testing semi-crystalline, amorphous, elastomeric, and fabric-reinforced geomembranes.

1.3 This practice is intended to be used in conjunction with Practice D 5322 or Practice D 5496, or both. The scope of this practice is limited to testing and reporting procedures for unexposed and exposed geomembrane samples.

1.4 Evaluation and interpretation of test data are 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
