Standard Practice for Manufacturing Quality Control of Geotextiles
4.1 Geotextiles are to be properly manufactured in a manner consistent with a minimum level of quality control as determined by in-house testing of the final product. This practice sets forth the types of tests, the methods of the testing, and the minimum testing frequencies appropriate for geotextile manufacturing quality control.
4.2 It should be clearly recognized that manufacturers may perform additional tests or at a greater frequency than set forth in this practice, or both. In this case the manufacturer’s quality control plan will take precedence over this practice.
4.3 It should also be recognized that purchasers and installers of geotextiles may require additional tests or at a greater frequency than called for in this practice, or both. The organization(s) producing such project-specific specification or quality assurance plan should recognize that such requirements are beyond the current state of this practice. If such a request is made by the purchasers or installers, they should clearly communicate the requirements to the manufacturer or supplier during the contract decisions in order that disputes do not arise at a subsequent time.
4.4 This practice provides guidance for sampling and testing as well as proper management of test data and certifications.
1.1 This practice covers the manufacturing quality control of geotextiles, describing types of tests, the proper test methods, minimum testing frequencies, and best practices for sampling.
1.2 This practice does not address manufacturing quality assurance, product acceptance testing, or conformance testing. These are independent activities taken by organizations other than the geotextiles manufacturer.
1.3 This practice is intended to aid manufacturers, suppliers, purchasers, installers, and end users of geotextiles in establishing a minimum level of effort for maintaining quality control.
1.4 This practice covers procedures for sampling geotextiles for the purpose of manufacturing quality control (MQC). These procedures are designed to ensure that the correct number of representative samples are obtained and properly reported by the manufacturer.
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.6 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.
