(Practice)Standard Practice for Sampling of Geosynthetics for Testing
Standard Practice for Sampling of Geosynthetics for Testing
SCOPE
1.1 This practice covers three procedures for the sampling of geosynthetics for testing. This practice requires that instructions on taking laboratory samples and test specimens be part of every test method for geosynthetics.
1.1.1 The first procedure describes the sampling of production units for the purpose of manufacturer's quality control (MQC) (Table 1).
1.1.2 The second procedure describes the sampling of production units for the purpose of manufacturer's quality assurance (MQA) testing during the manufacturing process. This requires that backup statistical process control records be maintained during the manufacturing process (Table 2).
1.1.3 The third procedure describes the division of shipments of geosynthetics into lots and the determination of lot sample size for purchaser's specification conformance testing (Table 3).
1.2 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.
