    General description

    The cotton specially cut by DMT is part of the simulated house dust DMT test dust type 8® and is specified in IEC 62885 / IEC 60312 / DIN EN 60312. This cut cotton is also used as a pure component for various filter technology tests.
    (For fiber length distribution see standard)
    Since cotton is a natural product, the fiber structure and composition are subject to certain natural variations. DMT GmbH & Co. KG is accompanied by strict quality monitoring, which begins with the supplier to achieve a high batch to batch comparability.
    Our specifications must be strictly observed during storage. Increased humidity can greatly accelerate the natural decomposition process.

    Composition

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

    x (mm) q3(x) (%)
    0 - 0.2 0.75
    0.2 - 0.5 6.25
    0.5 - 1.2 22
    1.2 - 2.0 25
    2.0 - 3.2 22
    3.2 - 4 24

    Transport and Storage

    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
