scope:

1.1 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.

1.1.1 The first procedure describes the sampling of production units for the purpose of manufacturer's quality control (MQC) (Table 1).

TABLE 1 Number of Units to be Selected as Lot Sample-Manufacturers' Quality Control

Number of Units in Lot Number of Units Selected
 1 to 2  1
 3 to 8  2
 9 to 27 3
28 to 64 4
 65 to 125 5
126 to 216 6
217 to 343 7
344 to 512 8
513 to 729 9
730 to 1000 10
1001 or more 11

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).

TABLE 2 Number of Units to be Selected as Lot Sample-Manufacturer's Quality Assurance

Number of Units in Lot Number of Units Selected
  1 to 200 1
 201 to 500 2
 501 to 1000 3
1001 or more 4

1.1.3 The third procedure describes the division of shipments of geosynthetics and rolled erosion control products into lots and the determination of lot sample size for purchaser's specification conformance testing (Table 3).

TABLE 3 Number of Units to be Selected as Lot Sample-Purchaser's Specification Conformance

Number of Units in Lot Number of Units Selected
  1 to 200 1
 201 to 500 2
 501 to 1000 3
1001 or more 4

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.
