Standard test dust
DMT Red China Clay | 4.1.1.4
General description
With the help of DMT Red China Clay according to chapter 5.2.5 of the standard DEF-Stan 00-35 the erosion behavior and the formation of structural damage in flight by dust is simulated.
Composition
The specified particle size distribution is shown in the following table:
| x (µm) | Q3(x) (%) |
| 2.0 | 1.5 - 5.0 |
| 5.0 | 5.0 - 11.0 |
| 10.0 | 11.0 - 19.0 |
| 20.0 | 20.0 - 30.0 |
| 40.0 | 35.0 - 46.0 |
| 75.0 | 60.0 - 70.0 |
| 105.0 | 76.0 - 86.0 |
| 150.0 | 99.0 - 100.0 |
Transport and Storage
Partial segregation may occur during transport and storage. It is therefore recommended to homogenize the DMT Red China Clay | 4.1.1.4 before use, which can be achieved by mixing with a laboratory tumbler mixer. Please store in a dry and airtight original container.
Quality ensurance
In order to achieve reproducible quality, the raw materials and production are strictly controlled. The following quality controls are carried out:
Monitoring the particle size distribution of raw materials
Monitoring the particle size distribution of the end product
