International Codification System for Medium and High Rank Coals

摘要

This document introduces and describes a new international codification system for medium- and high-rank coals. It has been developed by the ECE Coal Committee's Group of Experts on the Utilization and Preparation of Solid Fuels, supported by an ad hoc meeting of specialists from European and overseas countries to assist in characterizing coals involved in the international coal trade. The international codification system was adopted by the ECE Coal Committee at its eighty-third session, in September 1987 (ECE/COAL/113, para. 51) and endorsed by the Economic Commission for Europe at its forty-third session in April 1988 (E/1988/36-E/ECE/1170, decision D (43)). 8 tabs.
