These methods cover the reduction of large samples of aggregate to the appropriate size for testing@ employing techniques that are intended to minimize variations in measured characteristics between the test samples so selected and the large sample. The values stated in SI units are to be regarded as the standard. This standard does not purport to address the safety concerns 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.
