    General description

    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.

    Composition

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

    x (µm) Q3(x) (%)
    0.97 2.0 - 2.4
    1.38 3.8 - 4.4
    2.75 10.3 - 11.1
    5.50 22.1 - 23.2
    11.0 42.3 - 43.6
    22.0 62.5 - 64.5
    44.0 82.0 - 83.5
    88.0 94.7 - 96.0
    124.50 97.2 - 98.6
    176.0 99.0 - 100.0
    248.90 100.0

    Transport and Storage

    Partial segregation may occur during transport and storage. It is therefore recommended to homogenize the PTI Arizona Test Dust A3 medium 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
