D6141-97 Standard Guide for Screening the Clay <br /> Portion of a Geosynthetic Clay Liner (GCL) for <br /> Chemical Compatibility to Liquids <br /> Copyright 1997 AMERICAN SOCIETY FOR TESTING AND MATERIALS, West Conshohocken, PA. <br /> All rights reserved. <br /> 1. Scope <br /> 1.1 This guide suggests procedures and test methods that can be used in the evaluation of the ability of the <br /> clay portion of a geosynthetic clay liner to resist change due to exposure to liquids. These liquids may <br /> come from a site, or be generated in a laboratory from a site-specific soil. <br /> 1.2 The scope of this guide is limited to short-term screening and is not intended to replace evaluation <br /> procedures that measure a performance property such as EPA 9100. Test Method D 5887, or other suitable <br /> ASTM standards as they become available. <br /> 1.3 This guide applies to the clay component of a GCL. The synthetic carrier components are covered <br /> independently as described in Practice D 5322. <br /> 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is <br /> the responsibility of the user of this standard to establish appropriate safety and health practices and <br /> determine the applicability of regulatory limitations prior to use. <br />
