The Arizona test dust A1 ultrafine forms the finest standard dusts of ISO 12103-1 and is used for various filter and environmental tests. The so-called Arizona test dust A1 ultrafine consists of 69 % - 77 % quartz. DMT test dust A1 ultrafine "epsd" corresponds to the specified particle size distribution of the ISO 12103-1 standard, but 98 % of this consists of quartz. The test dust is identified by an additional code "epsd". "epsd" stands for "equivalent particle size distribution".

The Arizona test dust A2 fine is used in various standard tests in the field of filtration and environmental simulation. The so-called Arizona test dust A2 fine consists of 69 % - 77 % quartz. DMT test dust A2 fine "epsd" corresponds to the specified particle size distribution of the ISO 12103-1 standard, but 98 % of this consists of quartz. The test dust is identified by an additional code "epsd". "epsd" stands for "equivalent particle size distribution". Below you will find an overview of standards in which the Arizona test dust A2 fine is used: DIN EN 60312: Dry vacuum cleaners for domestic use IEC 60312 (2010): Dry vacuum cleaners for domestic use IEC 62885: Devices for surface cleaning ISO / TS 11155-1: Road vehicles - Air filters for passenger compartments - Part 1: Test for particle filtration ISO / TS 19713-1: Road vehicles - Inlet air cleaning equipment for internal combustion engines and compressors - Part 1: Fractional efficiency testing with fine particles (0.3 µm to 5 µm optical diameter) ISO 16889: Fluid power - Filters - Multiple pass test method for determining the filter performance of a filter element ISO 16890-3: Air filters for general ventilation and air conditioning - Part 3: Determination of gravimetric efficiency and flow resistance in comparison to the absorbed mass of test dust ISO 2941: Fluid power - Hydraulic filter elements - Fracture and burst resistance test ISO 4548: Test methods for main flow lubricating oil filters for internal combustion engines ISO 5011: Intake air purification equipment for internal combustion engines and compressors - Power measurement DMT GmbH & Co KG carries out various filter technology tests and environmental simulations.

Analogous to the Arizona test dust A2 fine, the Arizona test dust A3 medium is also used in various normative tests. The so-called Arizona test dust A3 medium consists of 69 % - 77 % quartz. DMT test dust A3 medium "epsd" complies with the particle size distribution specified in the ISO 12103-1 standard, but 98 % of this consists of quartz. The test dust is identified by an additional code "epsd". "epsd" stands for "equivalent particle size distribution".

The coarsest test dust of ISO 12103-1 is the Arizona test dust A4 coarse. The so-called Arizona test dust A4 coarse consists of 69 % - 77 % quartz. DMT test dust A4 coarse "epsd" complies with the particle size distribution specified in the ISO 12103-1 standard, but 98 % of this consists of quartz. The test dust is identified by an additional code "epsd". "epsd" stands for "equivalent particle size distribution".

The test dust in accordance with ECE R 16 is used for testing the dust resistance of rolling devices.

DMT Type 8® test dust is used as simulated house dust in accordance with IEC 62885 (2016) / IEC 60312 (2010) / DIN EN 60312 (2014) Chapter 7.2.2.3. This simulated household dust is used according to chapter 5.9 (IEC 62885-2) to determine the change in suction pressure of filled dust containers. DMT GmbH & Co. also offers modifications of DMT Test Dust Type 8®. An example of this is the DMT test dust Type 8®
