Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 8899-1998 "microstructure grouping of coal and mineral determination." And GB/T 8899-1998 compared to The main changes are as follows. --- Added "Terms and Definitions" chapter. --- Deleted the "semi-vitrinite" content. This standard uses redrafted Law Amendment uses ISO 7404-3.2009 "Analysis of coal and rock - Part 3. maceral group consisting of test methods". This standard and ISO 7404-3.2009, compared with more adjustment in the structure, listed in Appendix A of this standard and ISO 7404-3.2009 The reg number control list. This standard and ISO 7404-3.2009 as compared to the existence of technical differences, these differences involve the provision has passed the gap in the outside margin Vertical single-line positions were marked, Appendix B gives a list of corresponding technical differences and their causes.
