【国外标准】 Standard Practice for Tests to Evaluate the Chemical Resistance of Geotextiles to Liquids

5.1 This practice provides a test procedure for determining the resistance of a geotextile 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 The specification of test procedures in this practice is intended to serve as a guide for those wishing to compare or investigate the chemical resistance of a geotextile to a potentially harsh chemical environment.5.3 This practice is for the chemical resistance assessment of geotextiles and is written in parallel to similar standard practices for geomembranes, geogrids, geonets, and geopipes. 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.1.1 This practice describes the procedures used for testing geotextiles for chemical resistance to liquids. Reinforcement geotextiles can also be tested per Practice D6213.1.2 This practice describes test methods for measuring changes in planar dimensions, tensile properties, and other optional physical, mechanical, and hydraulic properties caused by immersion in test liquids 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 either Practice D5322 or D5496. The scope of this practice is limited to testing and reporting procedures for unexposed and exposed geotextile 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific warning 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.
