DMT Dolomit mineral dust, also known as hard floor dust or crevice dust, meets the specifications of the IEC 62885-2 / IEC 60312 / DIN EN 60312-1 Chap. 7.2.2.1. In addition to the fine fraction, DMT Dolomite mineral dust also contains coarse particles up to 2 mm in size.
This composition is similar to the dust & sand found in reality on hard floors such as laminate, parquet or tiled floors. The corresponding standard test is described in Chapter 5, IEC 62885-2. This test dust is used to determine or evaluate the dust absorption of a vacuum cleaner on hard floors.

Transport and Storage
Partial segregation may occur during transport and storage. It is therefore recommended to homogenize the DMT Mineral Dust Type 1 | 7.2.2.1 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
