COMBUSTIBLE DUST TESTING LAB
The core activity of this test laboratory is to determine the fire-technical characteristics of all industrial dust.
Standardized test methods are used to determine fire-technical characteristics, which make it possible to describe the behavior of individual objects under their test load. These analyses are done mainly for the correct classification of the spaces in which these substances exist, which allows for the correct selection and installation of electrical and mechanical equipment.
The aim is to obtain measured data, i.e. technical-safety parameters, which are further used to create safety data sheets and in operationally related risk assessments of technologies, especially as background materials for the comprehensive processing of Explosion Protection Document.
Determination of fire-technical characteristics:
Preparation and modification of the object
Sieve analysis (mean grain size)
Basic chemical analysis
Minimum ignition temperature of dust layer
Minimum ignition temperature of dust cloud
Lower explosive limit
Determination of explosion parameters
Limiting oxygen concentration
Minimum ignition energy of dust cloud
Velocity of fire spreading across a dust layer
Susceptibility to self-ignition using the isothermal method
Classification of dust layers into classes of flammability according to their flammability behavior
