Particulate materials. Sampling and sample splitting for the determination of particulate properties
| Published By | Publication Date | Number of Pages |
| BSI | 2019 | 42 |
This International Standard 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.
