Particulate materials - Sampling and sample splitting for the determination of particulate properties
ISO 14488:2007 specifies methods for obtaining a test sample from a defined bulk of particulate material (powder, paste, suspension or dust) that can be considered to be representative of that bulk with a defined confidence level. It is particularly relevant to the measurement of particle size, size distribution and surface area.
