- Scope
- This standard specifies methods for dispersing pigments and extender pigments using oscillating mills. This method is suitable for preparing several sample dispersions for quality control of pigments. This section is to be used in conjunction with the assessment method described in GB/T 21867, using an agreed low viscosity paint base system. This section should be read together with GB/T 21868 1 2008. This method is limited to grinding low-viscosity abrasives so that the grinding balls can move freely. It is not suitable for determining optimal grindstock formulations for other dispersion technologies. Note: The advantage of the oscillation method is that it can test small amounts of grinding materials from different batches at the same time in a closed system with minimal solvent loss.
