Description of key information

The measured overpressure relative to the initial pressure (pm) was in three tests significantly above 0.3 bar. 
Therefore, the test item Zinc methacrylate is identified as dust explosible

Additional information

A study was performed to determine the dust explosivity of zinc methacrylate. The measured overpressure relative to the initial pressure (pm) was in three tests significantly above 0.3 bar

Additionals data explosion were performed to measure:

-Maximum Explosion Pressure (Pmax): 7.4 bar

-Max.Rate of pressure Rise (dP/dt)max: 519 bar/s

-Kst value: 141 bar.m/s : The relationship between Kst value and the physical severity of the dust explosion is weak explosion

-Minimum Ignition Energy: 10-25mJ
