Significance and Use
5.1 This test method is not recommended for acceptance testing due to its poor between-laboratory precision. In some cases the purchaser and the seller may have to test a commercial shipment of one or more specific materials by the best available method even though the method has not been recommended for acceptance testing of commercial shipments. In such a case, if there is a disagreement arising from differences in values reported by the purchaser and the seller when using this method for acceptance testing, the statistical bias, if any, between the laboratory of the purchaser and the laboratory of the seller should be determined with each comparison being based on testing specimens randomly drawn from one sample of material of the type being tested.
1.4 This test method specifically requires length in inches and mass in metric units, and is not contrary to ASTM policy. The values stated in inch-pound units are to be regarded as the standard. The information in parentheses is for information only.
