《GB/T 16773-2008煤岩分析样品制备方法》由TC42(全国煤炭标准化技术委员会)归口,TC42SC4(全国煤炭标准化技术委员会煤岩分会)执行,主管部门为中国煤炭工业协会。
本标准修改采用ISO 7404-2:1985(E)《烟煤和无烟煤的煤岩分析方法―――第2部分:煤样制备方法》(英文版)。
本标准规定了煤岩样品制备的材料、设备和制备步骤。
本标准适用于粉煤光片、块煤光片、煤岩薄片和光薄片的制备,焦炭光片的制备也可参照使用。
本标准代替GB/T 16773-1997《煤岩分析样品制备方法》。
本标准与GB/T 16773-1997相比的主要变化如下:
―――按GB/T 1.1-2000《标准化工作导则 第1部分:标准的结构和编写规则》的要求,取消了GB/T 16773-1997中篇的编号,将原来一篇的内容作为一章编写。
―――增加了定向块煤光片的制备方法。
―――在范围中增加了“焦炭光片的制备也可参照使用”。
