    General description

    DMT Pural NF is used to characterize the filtration behavior of cleanable filter media. Chapter 3.3 specifies the test dust with a particle size distribution < 20 µm.
    Note: Pural NF is the trade name of a Sasol product. This information is only intended to inform users of the International Standard.

    Composition

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

    x (µm) Q3(x) (%)
    1.20 10.0
    4.5 50.0
    15.0 - 20.0 90.0

    Transport and Storage

    Partial segregation may occur during transport and storage. It is therefore recommended to homogenize the DMT Pural NF 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
