(Practice)Standard Practice for Determining the Specification Conformance of Geosynthetics
Standard Practice for Determining the Specification Conformance of Geosynthetics
SIGNIFICANCE AND USE
This practice provides a means by which the purchaser can determine the conformance of geosynthetic properties as applied to the acceptance or rejection of a material in regards to a material specification.
This practice has been developed with strong emphasis on practicality and the realization that all geosynthetics are subjected to a vigorous quality control program prior to shipping.
Note 1—It is suggested that the user obtain the mean, standard deviation, and/or the coefficient of variation for given physical/mechanical properties of a product directly from the manufacturer. If this data is unavailable, it is suggested that users of this practice begin to accumulate data that can be used to estimate product averages and standard deviations for each product.
Note 2—The risk to the purchaser of buying out of specification materials is minimal when conformance requirements are detailed in the purchase specification and adequate conformance testing is performed. It is the producer’responsibility to perform thorough quality control testing for all properties requiring certification. The producer’risk of rejection is minimal with the performance of this thorough quality control testing.
SCOPE
1.1 This practice covers a procedure for determining the conformance of geosynthetic properties to standard specifications.
1.2 This standard does not purport to address all of the safety problems, 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.
