Moonex Technologies Since 2019 we are exclusive supply of all DMT test dust products in india . Also other regions like sri Lanka , Nepal , Bhutan and have been included in this trade agreement. the DMT group provides independent services in the four main fields of Exploration, Engineering, Consulting and Geotechnics. It also develops products and offers solutions for industrial metrology and testing with emphasis on natural resources, safety and infrastructure.
DMT GmbH & Co. KG is an independent engineering and consulting company which specialises in the sectors of product testing and building safety, industrial testing and measuring technology, construction and infrastructure, mining and coke making technology as well as raw materials exploration and geology.
We provide a wide range of safety relevant services. Based on standards, rules, guidelines and legal regulations our test engineers and technicians as well as our specialists in the fields of dust removal and filter technology, test dust production, air pollution control, ventilation, refrigeration and air-conditioning engineering as well as fire prevention.
Our know-how in filters, separation technology and dusts allows us for example to evaluate the air pollution characteristics of household appliances such as vacuum cleaners. Mineral test dusts e. g. Dolomite DMT test dust and synthetic household test dust DMT type 8® both according to IEC 60312 and different others are produced and sold to vacuum cleaner industry as dust standards.

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.
The DMT ASHRAE test dust is described in the ANSI / ASHRAE standard. This is used, for example, for filter testing in accordance with EN 779.
DMT beech wood dust is used to measure vacuum, cleaning interval and residual dust content according to DIN EN 16770. According to the specification, the median particle size is approx. 100 µm, whereby the d90 is between 20 - 300 µm. The wood moisture content is set between 6 - 10 %.
DMT Cellulose Dust is one of the three components of DMT Test Dust Type 8® and is specified in Chapter 7.2.2.6.

The DMT CN / ISO reference sand is specified in both ISO 679 and DIN EN 196.
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.
The DMT Dolomit DRB 4/15 complies with the specification of DIN EN 149 and is used for the testing of paricle-filtering half masks / breathing masks. Add to cart

DMT Dolomit mineral dust, also known as hard floor dust or crevice dust, meets the specifications of the IEC 62885-2 / IEC 60312 / DIN EN 60312-1 Chap. 7.2.2.1. In addition to the fine fraction, DMT Dolomite mineral dust also contains coarse particles up to 2 mm in size. This composition is similar to the dust & sand found in reality on hard floors such as laminate, parquet or tiled floors. The corresponding standard test is described in Chapter 5, IEC 62885-2. This test dust is used to determine or evaluate the dust absorption of a vacuum cleaner on hard floors.
DMT mineral dust type 2 is produced in accordance with the IEC 62885 (2016) / IEC 60312 (2010) / DIN EN 60312 (2014) Chapter 7.2.2.2. The particle size range is between 90 µm - 200 µm. This mineral dust is used for dust absorption testing on carpets as described in Chapter 5, IEC 62885-2. (Reference to ISO 679 / CEM 1 Description ) With a particle size range between 90 - 200 µm it is possible that partial demixing may occur during transport. It is therefore recommended to homogenize DMT Carpet Mineral Sand Type 2 before use, which can be achieved by mixing it with a laboratory tumble mixer.
