Meide白lgye FenxjFa邝梦a(煤的工业分析方法》(GB/T 212一l卯l)(乃琳初切叱月朋加‘of。刃l)对褐煤、烟煤和无烟煤的水分、灰分、挥发分的测定和固定碳的计算。煤是中国重要资源，是国民经济的一种主要能源，因此必须对煤的分析方法规范化，才能准确区分各类煤质，以保证煤的充分利用。为此于1%3年发布了《煤的工业分析方法)( GBZ12)国家标准，具体规定了烟煤和无烟煤、揭煤水分的测试方法，规定了灰分和挥发分测定方法以及固定碳的计算方法。为了保证更有效地利用中国煤炭资源，在工业和民用中不造成浪费，于1更抖年又发布了《煤炭质量分级煤炭灰分分级》(G脚T巧乞抖.1)、(煤炭质量分级煤炭硫分分级》(GBIT152洲.2)和《煤炭质量分级煤炭发热量分级》(GBIT15乞场.3)等3个国家标准。这些标准的实施，不仅统一了测试和计算方法，而且在煤炭勘探、生产和加工中提高了利用率，降低了损耗，显著增加了经济效益。 (陈志田)
