Foreword
GB/T 15224 “Classification for quality of coal” consists of three parts.
- Part 1. Ash;
- Part 2. Sulfur content;
- Part 3. Calorific value.
This Part is Part 1 of GB/T 15224.
This Part replaces GB/T 15224.1-2010 “Classification for quality of coal - Part
1. Ash”.
Compared with GB/T 15224.1-2010, in addition to editorial modifications, the
