Dust explosion protection terminology1 ScopeThis document defines the terminology for dust explosion protection. This document is applicable to the formulation of dust explosion prevention standards, the preparation of technical documents, and the compilation and translation of professional manuals and teaching materials. This document does not apply to dust from underground coal mines, fireworks, explosives and strong oxidizers.2 Normative referencesThis document has no normative references.3 Basic terminology3.1 Dust In the atmospheric environment, fine solid particles may settle down according to their own weight or may remain suspended in the air for a period of time. 3.2 Combustible dust Dust (3.1), fibers or flying catkins that can undergo violent oxidation reactions with gaseous oxidants under atmospheric conditions. Note 1.The gaseous oxidant is mainly air. Note 2.Combustible dust can cause dust explosion under certain conditions. 3.3 Dust cloud A mixture of combustible dust (3.2) and gaseous oxidant in a certain concentration suspended in the gaseous oxidant in an atmospheric environment. 3.4 Dust layer Combustible dust (3.2) group deposited (pile) on the ground or on the surface of objects. 3.5 Conductive dust conductivedust Metal dust or dust with a resistivity less than or equal to 103Ω·m (3.1). 3.6 Dust explosion In the atmospheric environment, dust (3.1) undergoes a violent oxidation reaction with gaseous oxidants, causing a significant jump in pressure and temperature. 3.7 Dust deflagration Dust explosion in which the flame propagation velocity is lower than the speed of sound in the original dust cloud (3.6). 3.8 Dust detonation Dust explosion in which the flame and shock wave propagation speed exceeds the speed of sound in the original dust cloud (3.6). 3.9 Secondary explosion subsequentexplosion When a dust explosion (3.6) occurs, the shock wave generated by the initial explosion will lift up the deposited dust that has not exploded, forming a new explosion. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 15604-2024_English be delivered?Answer: Upon your order, we will start to translate GB/T 15604-2024_English as soon as possible, and keep you informed of the progress.
