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
main technical deviations in this Part are as follows.
- added “GB/T 482” “GB/T 30732” “MT/T 1090” as references in normative
references (see Clause 2 of this Edition);
- deleted “GB/T 475” “GB/T 19494.1” “Procedures for coal sampling of coal
resource exploration (formerly issued by the Ministry of Coal in 1979)” from
normative references (see Clause 2 of this Edition);
- modified “medium ash” as “high ash”, “high ash” as “ultra-high ash” (see
Table 1 of this Edition);
- added the note to the table that “if the ash is greater than 40%, the coal
resource reserves shall not be calculated” (see Table 1 of this Edition);
- deleted the classification of commercial ash (see Clause 4 of Edition 2010).
This Part was proposed by China Coal Industry Association.
This Part shall be under the jurisdiction of National Technical Committee on
