Laboratory occupies with the problems connected with dust explosions and the methods of combating in all the branches of industry except underground mining plants.

The activity of the Laboratory includes:

RESEARCH WORKS:

• experimental explosions in large scale and in laboratory scale with the measurement of the parameters characterizing the explosion;

• numeric simulations of dust-air mixture explosion;

• verification and calibration of dust explosion models with the usage of experimental results.

SERVICE WORKS CONDUCTED FOR INDUSTRY:

• determination of ignitability and explosiveness of dust;
  Laboratory determines full range of standard parameters of ignitability and explosiveness according to current European norms:
  - e xplosiveness dust test according to VDI 2263;
  - characteristics of explosiveness including: maximum explosion pressure P_max and explosiveness indicator K_{st max};
  - lower limit of dust explosiveness;
  - minimum temperature of dust layer ignition DGW;
  

  - minimum temperature of dust cloud ignition T_CL;

  - minimum temperature of dust layer ignition T_5mm;
  - minimum energy of dust cloud ignition MIE;
  - determination of self-ignition of dust accumulation susceptibility SIT;

  - limiting oxygen concentration for explosion GST;

  - resistivity of dust layer _ρ
• dust explosion risk assessment:
  - for working installations (directive 1999/92/WE ATEX 137);
  - on the basis of installation project (directive 1999/92/ WE ATEX 137);
  - for devices and protective systems destined for operation in atmospheres endangered by dust explosion (di rective 94/9/WE ATEX 95).

• examinations of devices within the certification process (directive 94/9/WE ATEX 95);
• consultations concerning dust explosion hazard problems.
