《GB/T 26930.6-2014原铝生产用炭素材料 煤沥青 第6部分：灰分的测定》由TC243（全国有色金属标准化技术委员会）归口，TC243SC1（全国有色金属标准化技术委员会轻金属分会）执行，主管部门为中国有色金属工业协会。
GB/T26930的本部分规定了原铝生产用煤沥青中灰分的测定方法。
本部分适用于原铝生产用煤沥青中灰分的测定。测定范围≥0.05%。
如果需要用干基样品来表述结果,减去用 GB/T26970.1(共沸蒸馏法)测定的水分,将测定的灰分结果换算得到干基下的结果。
注:试验得到的灰分可以用于元素含量的测定。
Scope
This part of GB/T 26930 specifies the method for the determination of ash in coal tar pitch used in the production of primary aluminum. This section applies to the determination of ash in coal tar pitch used in primary aluminum production. Measuring range ≥ 0.05%. If it is necessary to express the results on a dry basis, subtract the moisture measured by GB/T 26970.1 (azeotropic distillation method), and convert the measured ash content to obtain the results on a dry basis.
