《GB/T 21780-2008粒度分析 重力场中沉降分析 吸液管法》由TC251(全国危险化学品管理标准化技术委员会)归口,主管部门为国家标准化管理委员会。
本标准为首次发布。本标准规定了采用重力场中的沉降分析-吸液管法分析粒度的方法。本标准适用于吸液管法测量弥散在液体中的固体物质分布累计曲线(符合DIN 66141的规定),所使用的吸液管装置的沉降速度当量直径范围是1um~250um。本标准等同采用DIN66115:1983《粒度分析 重力场中沉降分析 吸液管法》(德文版)。
Scope
This standard specifies the method of particle size analysis by sedimentation analysis in the gravity field - pipette method. This standard is applicable to the pipette method for measuring the cumulative particle size distribution curve of solid substances dispersed in liquids (according to DIN 66141). The pipette device used has a settling velocity equivalent diameter range of 1 μm to 250 μm.
