Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces SN 0067-1992 "export coal mechanical sampling sample preparation method."
This standard compared with SN 0067-1992, the main technical changes are as follows:
--- All terms and definitions have been updated;
--- Adjust the original standard narrative structure;
--- Deleted the original standard application look-up table, change the formula method;
--- Original standard part of the narratives of editorial changes to the text.

Yung. This standard is consistent with the aforementioned standard non-equivalent, the main differences are as follows:
--- To maintain the original structure and SN standard level;
--- Remove the belt and the flow of coal flow sampling irrelevant content.
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
This standard was drafted: People's Republic of China Exit Inspection and Quarantine of Hebei, People's Republic of China Guangdong Entry-Exit Inspection and
Quarantine Bureau.

This standard replaces the standards previously issued as follows:
--- SN 0067-1992.
