    General description

    In the description of the test procedure for motor vehicle headlamps emitting an asymmetrical passing-beam or a driving-beam the test dirt is specified which simulates the real dirt.
    The test dirt is used for headlamps with an outer lens made of glass.

    Composition

    The composition of the test dirt is as follows:
    9 parts quartz sand between 0 µm and 100 µm
    1 part beech coal
    0.2 parts carboxymethylcellulose

    Transport and Storage

    Partial segregation may occur during transport and storage. It is therefore recommended to homogenize the DMT Test Dirt ECE R113 1.2.1.1.1 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
