DMT Aramco Test Dust DMT Aramco Test Dust
For the testing of gas turbine and diesel engine filters, these are often tested according to Aramco standard 32-SAMSS-008. The Aramco test dust specified in the above standard is used for this purpose. The specification specifies that the particle size distribution of sodium chloride in the test dust must be between 0-5 µm. The DMT GmbH & Co. KG produces DMT Aramco test dust using a special process so that the sodium chloride, which can become highly agglomerated at normal air humidity and thus clearly > 5 µm, meets the given specification.

DMT Cut Cotton („Cotton-Linters“) | 7.2.2.3 DMT Cut Cotton („Cotton-Linters“) | 7.2.2.3
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.
