Welcome to DustLab!

The knowledge of the parameters related to materials applied in potentially explosive atmospheres is essential. Many materials are known in sufficient detail, but the explosion safety parameters of many materials are not or not fully known. The situation is further complicated if their mixture is the basis of a potentially explosive atmosphere.

DustLab provides the opportunity for a fact-based approach to potentially explosive atmospheres and if the highly flammable and explosive substances used therein, as well as for the implementation of user specification, design, operation and further assessment based on them.


What exactly is DustLab?

A laboratory focusing on parameters on hazardous area compliance related to dust-, gas- and their mixture, where detailed theoretical knowledge and up-to-date practical experience meet. The co-operation between ExNB Certification Institute and the University of Miskolc gives the management and operation of DustLab, where we can assess and certify hazardous parameters of dust, gas particles and their mixtures.

Why DustLab?

We have a fleet of equipment to meet the technical and safety requirements of the modern age, so that we can determine the explosion safety technical parameters of a given dust and gas or their mixtures. The theoretical and practical experts of ExNB and the University of Miskolc can support the users with specific application technology knowledge in addition to the laboratory results and implement safe operation together.

DustLab participates in international reference measurements every year to ensure the accuracy of the measurements.


What else does DustLab offer?

The close cooperation between the ExNB and the University of Miskolc within the framework of DustLab enables it to provide its partners with access to the full portfolio and competence library of both the ExNB and the University of Miskolc. Further analyzes, measurements and related consultations are available, e.g. conductivity, microscopic or laser particle analysis, special thermal properties, explosion safety compliance, regulatory consultations, etc.


Further possible measurements

Autoignition Temperature of Solids; BAM fall hammer (impact tester); BAM friction test; Powder Resistivity Test Apparatus; Powder Chargeability Test Apparatus; Charge Decay Test
