    General description

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

    Composition

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

    x (µm) Q3(x) (%)
    0.97 4.5 - 5.5
    1.38 8.0 - 9.5
    2.75 21.3 - 23.3
    5.50 39.5 - 42.5
    11.0 57.0 - 59.5
    22.0 73.5 - 76.0
    44.0 89.5 - 91.5
    88.0 97.9 - 98.9
    124.50 99.0 - 100.0
    176.0 100.0

    Transport and Storage

    Partial segregation may occur during transport and storage. It is therefore recommended to homogenize the DMT Mineral Dust Type 4 | 7.2.2.5  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
