The behaviour of e.g.: raw materials, intermediate and final products is a necessary information to guarantee safe unit operations such as grinding, drying, evaporating.
The safety technical behaviour of the materials is basically characterized by the following properties.

 

 

Physical properties		Particle size distribution (median value)
Flammability and Burning Characteristics		Combustibility test (Combustion class, CC) Minimum ignition temperature of a 5mm dust layer (MIT5mm)
Dust Explosion Characteristics		Dust explosibility test in a modified Hartmann apparatus Lower explosion limit (LEL) Limiting oxygen concentration (LOC) Maximum explosion pressure (Pmax) and maximum rate of explosion pressure rise (dp/dt)max Minimum ignition energy (MIE ≤ 1 J) Minimum ignition energy (MIE > 1 J) Minimum ignition temperature of a dust cloud (MITcloud) Impact sensitivity (Falling hammer test)
Static Electricity		Specific powder resistivity of bulked powder
Thermal Decomposition and Self-Ignition		Differential scanning calorimetry (DSC) Decomposition test (Lütolf dynamic) Decomposition test dynamic (Grewer air) Spontaneous decomposition (Deflagration) Self ignition temperature (Wire Basket isoperibolic) Decomposition Gas

 

FireEx companies assist you to select, coordinate and interpret the appropriate laboratory tests, and consequently recommend the necessary technical and organizational safety measures.
