Web31 aug. 2024 · The grades and groups of hazardous substances are classified according to their performance parameters. These performance parameters include: flash point, ignition point, ignition temperature, explosion limit, minimum ignition current ratio, minimum ignition energy, maximum test safety gap, etc. 1) Flash point. Web(1) Criteria used for classification of gases in gas groups according to IEC 60079-20-1 => These criteria indicate that exclusively MIC ratio values are sufficient to assign a gas mixture into a gas group for the following cases: Group IIA: MIC ratio > 0.9 Group IIB: 0.5 ≤ MIC ratio ≤ 0.8 Group IIC: MIC ratio < 0.45 Concerning the case of

Web1 apr. 2024 · The explosion group for gases and vapors is determined by the maximum experimental safe gap (MESG) and/or minimum ignition current (MIC) ratio values, both defined in the IEC 60079-20-1 (Explosive Atmosphere—Part 20-1: Material characteristics for gas and vapour classification—Test methods and data) standard. Webnarrow gap. The minimum ignition current (MIC) – a variable for the minimum ignition energy of emergent gases and vapours – is definitive for intrinsic safety. Equipment in dust explosion hazardous areas (Group III) is classified according to dust type into Group IIIA (combustible lint), IIIB (non-conductive dust) and IIIC (conductive dust).
WebThe current standard adopted by the European Union, based on the earlier German standard (DIN 51649, 1986), is a radical departure from the above considerations. In that standard (EN 1839T), a sepa ration of flame 10 cm above the 0.2–0.5 s induction spark in an 8 x 30 cm cylinder defines a flammable mixture. The same is true if
