ASTM D4354-12

This practice covers three procedures for the sampling of geosynthetics and rolled erosion control products (RECPs) for testing. This practice requires that instructions on taking laboratory samples and test specimens be part of every test method for geosynthetics.

This practice gives three procedures for sampling: one for manufacturer's quality control (MQC), one for manufacturer's quality assurance (MQA) testing, and a third for purchaser's specification conformance testing. For this reason, test methods containing a section on sampling that requires the use of this practice should contain a statement in the section on reporting similar to the following:

Report which procedure from Practice D4354 was used for sampling:

Procedure A for Manufacturer's Quality Control (MQC),

Procedure B for Manufacturer's Quality Assurance (MQA) Testing, or

Procedure C for Purchaser's Specification Conformance Testing.
