Standard Practice for Laboratory Immersion Procedures for Evaluating the Chemical Resistance of Geosynthetics to Liquids

Significance and Use

4.1 This practice provides a standard immersion procedure for investigating the chemical resistance of a geosynthetic to a liquid waste, leachate, or chemical in a laboratory environment. The conditions specified in this practice are intended both to provide a basis of standardization and to serve as a guide for those wishing to compare or investigate the chemical resistance of a geosynthetic material(s) in a laboratory environment. Practice D5496 can be used should the user need to assess the performance of a geosynthetic in field conditions.

4.2 This practice is not intended to establish, by itself, the behavior of geosynthetics when exposed to liquids. Such behavior, referred to as chemical resistance, can be defined only in terms of specific chemical solutions and methods of testing and evaluation criteria selected by the user.

Scope

1.1 This practice covers laboratory immersion procedures for the testing of geosynthetics for chemical resistance to liquid wastes, prepared chemical solutions, and leachates derived from solid wastes.

1.2 This standard is not applicable to some geosynthetics such as geosynthetic clay liners (GCLs), because of their composite nature requiring a confining pressure during immersion. However, individual geosynthetic components of the GCL can be tested.

1.3 This standard was originally developed to supplement and expand EPA 9090 to include all geosynthetics. EPA 9090 has not been updated since 1992.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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. For specific hazards statements, see Section 7.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
