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

Transport and Storage
Partial segregation may occur during transport and storage. It is therefore recommended to homogenize the DMT Test Dust A2 fein 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
