Significance and Use
5.1 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.
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 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.
1.3 This practice is intended to be used in conjunction with Practice D5322 or Practice D5496, or both. The scope of this practice is limited to testing and reporting procedures for unexposed and exposed geomembrane samples.
1.5 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.
1.6 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.
