ISO 20977-2018 石灰材料--干法和湿法筛分粒度分布的测定 Liming materials — Determination of size distribution by dry and wet sieving

This document specifies two methods for the determination of the particle size distribution of liming 
materials.
Method A (the dry sieving method) is applicable to all liming materials except wet and paste-like 
products. Method A is not applicable if blinding, caking, electrostatic charges or agglomeration occur 
after drying.
Method B (the wet sieving method) is applicable to products which are susceptible to blinding, caking, 
electrostatic charges or agglomeration after drying. Method B can be used to determine the primary 
particle size distribution of granulated products. Method B is not applicable to burnt lime and liming 
materials containing water-soluble constituents.st edition 2018-12 Liming materials — Determination of size distribution by dry and wet sieving Amendements minéraux basiques — Détermination de la distribution granulométrique par tamisage à sec ou à l'état humide Reference number ISO 20977:2018(E) ？ ISO 2018 ISO 20977:2018(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2018 All rights reserved.
