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.

DMT mineral dust type 2 is produced in accordance with the IEC 62885 (2016) / IEC 60312 (2010) / DIN EN 60312 (2014) Chapter 7.2.2.2. The particle size range is between 90 µm - 200 µm. This mineral dust is used for dust absorption testing on carpets as described in Chapter 5, IEC 62885-2. (Reference to ISO 679 / CEM 1 Description ) With a particle size range between 90 - 200 µm it is possible that partial demixing may occur during transport. It is therefore recommended to homogenize DMT Carpet Mineral Sand Type 2 before use, which can be achieved by mixing it with a laboratory tumble mixer.

DMT Type 3 mineral dust is used as a mineral component in DMT Type 8 test dust.

DMT mineral dust type 4 is used for testing according to chapter 5.11.
