《GB/T 3520-2008石墨细度试验方法》由609(中国建筑材料联合会)归口,TC406(全国非金属矿产品及制品标准化技术委员会)执行,主管部门为中国建筑材料联合会。
本标准1983年首次发布,1995年第一次修订,本版为第二次修订。
本标准规定了石墨产品细度的试验方法。
本标准适用于38μm~500μm鳞片石墨与微晶石墨产品的细度试验。
本标准代替GB/T 3521-1995《石墨细度检验方法》。与GB/T 3521-1995相比,本标准做了如下修改:
―――将1995版引用标准中“GB 6003”修改为“GB/T 6003.1 金属丝编织网试验筛”;
―――将1995版“方法原理概要”编入本版“方法概述”中;
―――增加了旋转气流筛原理图;
―――增加了两种标准筛的规格要求;
―――将1995版“筛检方法(一)、筛检方法(二)”修改为“负压筛析法、振筛机法”
―――增加了负压筛析法中筛分时间按标准筛筛孔尺寸确定;
―――将1995版筛检方法(一)中的试验用样量5g修改为10g;
―――将1995版5.1.1和5.2.1的设备、仪器的英文序号修改为数字序号;
―――增加了术语“筛分终点”和“细度”的英文。
