1. Scope

1.1 This practice describes the procedures used for testing geotextiles for chemical resistance to liquids.

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 Practices 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see Section 7.

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