ASTM D2013-03<\/h3>\n

Historical Standard: Standard Practice of Preparing Coal Samples for Analysis<\/h4>\n
\n

ASTM D2013<\/h4>\n

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

1.1 This practice covers the reduction and division of gross or divided samples, and the preparation of composite samples, up to and including the individual portions for laboratory analysis.<\/p>\n

1.2 Reduction and division procedures are prescribed for coals of the following groups:<\/p>\n

1.2.1 Group Aincludes coals that have been cleaned in all sizes.<\/p>\n

1.2.2 Group Bincludes all other coals. Unknown coals are to be considered under Group B.<\/p>\n

1.2.3 Group A allows smaller weight laboratory samples to be retained than Group B. These lower weights may be used for particular coals if they have been shown, by using the procedures of Annex A1.2, to give a sample preparation and analysis variance which is no more than 20 % of the total analysis variance.<\/p>\n

1.3 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.<\/p>\n

1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information purposes only.<\/p>\n
