Standard test dust
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.
The specified particle size distribution is shown in the following table:
|x (µm)||Q3(x) (%)|
|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.
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
