The DMT coal dust EN 60079-1 is used, among other applications, for testing device protection through flameproof encapsulation. The requirements are defined in the Code of federal regulations 30 CFR 7.306(a)(3). The dust must contain at least 22% volatile matter, at least 11,000 BTU and pass through a 200 mesh U.S. Standard sieve. We monitor the volatile components, caloric properties and particle size distribution in our own laboratory and technical center. In addition, the dust is characterized using laser diffraction in order to provide consistent properties.
Composition
Steinkohle aus US-amerikanischer Herkunft.
Transport and Storage
Store in a dry place.
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 volatile matter of raw materials Monitoring the heat constant of raw materials Monitoring the particle size distribution of the end product
