Sampling and conditioning are equally as important as testing. The reliability of the test results depends primarily upon how well the specimens tested represent the true character and condition of the lot of asbestos fiber. Much care and effort are required to be sure that all the sampling operations are systematic or at random and are representative. Failure to provide a test specimen that accurately represents the lot from which it is drawn will produce misleading test results regardless of the accuracy and the precision of the test method.

1. Scope

1.1 This test method covers procedures for taking a composite or a master composite sample, at the mine or at the factory or from a consignment, of a lot of milled asbestos fiber used as raw material in the chrysotile asbestos industry, conditioning this sample and reducing it in quantity through a series of steps to provide a relatively small test specimen of loose asbestos fibers, representative of the lot and suitable for the determination of a single property.

1.2 This sampling method is suitable for taking test specimens of chrysotile asbestos for Test Methods: C1119, C1120, C1121, C1122, C1123, C1124, C1125, C1162, D1118, D2589, D2752, D2946, D2947, D2985, D2987, D3639, D3752 and D3880.

1.3 Test Method D3879 covers the sampling of amphibole asbestos fibers.

1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.5 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. ^REFERENCE
