ASTM D2234\/D2234M-03e1<\/h3>\n

Historical Standard: Standard Practice for Collection of a Gross Sample of Coal<\/h4>\n
\n

ASTM D2234\/D2234M<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This practice covers procedures for the collection of a sample under various conditions of sampling. The sample is to be crushed and further prepared for analysis in accordance with Method D 2013. However, the procedures for dividing large samples before any crushing are given in this practice.<\/p>\n

1.2 This practice describes general and special purpose sampling procedures for coals (1)<\/i> by size and condition of preparation (for example, mechanically cleaned coal or raw coal) and (2)<\/i> by sampling characteristics.<\/p>\n

1.3 The values stated in either SI units or inch-pound units are to be reagarded seperately as standard. The values stated in each system may not be exact equivalents; therefore, use each system independently of the other. Combining values from the two systems may result in nonconformance with the standard.<\/p>\n

1.4 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.<\/i><\/p>\n
