ISO 2926:2013 主要用于铝生产的氧化铝.45 m至150 m范围的粒度分析.电沉积筛分法

This International Standard specifies a dry sieve method using electroformed sieves for determining the mass distribution of the particle sizes in aluminium oxide used for the production of primary aluminium. This method is applicable to calcined aluminium oxide containing a maximum of 20% mass fraction of particles having a mean diameter exceeding 150μm,and containing a maximum of 15% mass fraction of particles having a mean diameter less than 45μm. This method is not applicable to the use of woven wire sieves.

ISO 20998-2:2013 利用声学法测量和表征粒子特性 第2部分 线性理论指南

This part of ISO 20998 describes ultrasonic attenuation spectroscopy methods for determining the size distributions of a particulate phase dispersed in a liquid at dilute concentrations, where the ultrasonic attenuation spectrum is a linear function of the particle volume fraction. In this regime, particle–particle interactions are negligible. Colloids, dilute dispersions, and emulsions are within the scope of this part of ISO 20998. The typical particle size for such analysis ranges from 10 nm to 3 mm, although particles outside this range have also been successfully measured. For solid particles in suspension,size measurements can be made at concentrations typically ranging from 0,1 % volume fraction up to 5 % volume fraction, depending on the density contrast between the solid and liquid phases,the particle size,and the frequency range.
