E877-08 Standard Practice for Sampling and Sample Preparation of Iron Ores and Related Materials for Determination of Chemical Composition
Published By | Publication Date | Number of Pages |
ASTM | 2008 | 9 |
1.1 This practice covers procedures for mechanical sampling of iron ores and related materials in a falling stream or stopped-belt sampling and preparing the gross sample to the various test samples required for each characteristic to be measured. Included as Annexes are ( 1 ) design criteria to prevent bias, ( 2 ) statistical methods to determine quality variation and precisions of sampling and division, and ( 3 ) a method for comparing two sampling procedures for possible systematic differences.
1.2 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. Specific precautionary statements are given in Section 8.
