标准范围

规定的方法也可用于检查其他不溶于水的粉末或颗粒。它既不适用于疏水性材料,也不适用于粒状材料。在试验装置中,分散在水中的受试材料通过旋转水射流系统进行离心运动。水将细颗粒冲过筛子,粗颗粒留在筛子上。筛上的残渣干燥并称重。-取消并取代ISO 787/18-1973,并构成其技术修订版。

The method specified can also be applied to the examination of other powders or granules which are insoluble in water. It is neither applicable to hydrophobic nor pelletized materials. In the test apparatus the material under test, dispersed in water, is brought into centrifugal motion by a system of rotating jets of water. he water flushes the fine particles through the sieve, the coarse particles being retained on the sieve. The residue on the sieve is dried and weighed. - Cancels and replaces ISO 787/18-1973 and constitutes its technical revision.
