    General description

    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".

    Composition

    The specified particle size distribution is shown in the following table:

    x (µm) Q3(x) (%)
    0.97 3.0 - 5.0
    1.38 7.0 - 10.0
    2.75 23.0 - 27.0
    5.50 65.0 - 69.0
    11.0 95.5 - 97.5
    22 100.0

    Transport and Storage

    Partial segregation may occur during transport and storage. It is therefore recommended to homogenize the DMT Test Dust A1 ultrafine 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
