How is the total incombustibility of collected dust analyzed?

The total incombustibility of collected dust is analyzed using a device known as a 'volumeter.' This device measures the volume of gases released during combustion processes, allowing for the assessment of the incombustible content of the dust samples. By determining how much of the dust does not combust, it's possible to gain insights into its composition and behavior in terms of fire and explosion hazards.

Weighing the samples provides basic mass data but does not specifically address their incombustible characteristics. Visual inspection methods may offer qualitative insights, but they lack the precision and scientific rigor required for an accurate analysis of incombustibility. Chemical reactions can provide information on the dust’s composition, but they do not directly measure the total incombustibility in the way a volumeter does. Thus, the use of a volumeter is the most effective and valid method for this specific analysis.
