本标准5.2)，增加了褐煤蜡样的称样粒度(本标准5.3.1);

—褐《煤蜡中溶于丙酮物质(树脂物质)测定方法》(GB/T2561):改正了原标准计算公式中有误的地

方(原标准二中9;本标准6.5.1)，增加了小于0.1rnm褐煤蜡样的制备方法(本标准6.3);

一一《褐煤蜡中苯不溶物测定方法)))(GB/T2562):对原标准中的图和有关名称做了修改(原标准一

中1.(1);本标准7.2.1),删去了原标准中的附录，将其中实质性的内容移至正文中有关章节

中(本标准7.2.1.3);

一《褐煤蜡灰分测定方法》(GB/T2563):将原标准中“高温炉”改为“马弗炉”(原标准中一中

1.0);本标准8.2.3)，并修改了马弗炉的温控精度(原标准中二中2;本标准8.3.1),增加了

在低温炭化时如发生着火试验作废的规定本〔标准8.3.3);

—《揭煤蜡酸值和皂化值测定方法》(GB/T2564),将原标准中的仪器做了修改(原标准中一中

1;本标准9,2)，对原标准中部分试剂的引用标准进行了修改(原标准中一中2;本标准9.2),

删除了原标准中的附录，将其中实质性的内容移至正文有关章节中(本标准9.2卜16和

9.2.17),改正了计算公式中有误的地方(原标准中四中8和乳本标准9.5.1和9.5.2);

—《褐煤蜡密度测定方法)(GB/T3813):对原标准中的仪器、材料和试剂做了修改(原标准中1;
