Differences between Intrinsic Safety and Coal Mine Safety mark certifications

Thread Content

Many customers, when inquiring about explosion-proof certification, mention intrinsically safe and coal safety, not understanding the relationship between them; they even thought they meant the same thing. Now, I’ll briefly explain the relationship between the two to you all. By intrinsically safe, we generally mean intrinsically safe design, which is one of the various explosion-proof protection types. Explosion protection types include intrinsically safe type, flameproof type, encapsulated type, positive pressure type, etc., referring to the type of protection adopted by the equipment. Coal safety refers to the safety in coal mines; coal safety certification generally denotes the mandatory certification required for equipment used underground in coal mines. Due to the presence of explosive gas in coal mines, explosion protection must be taken into account when applying for coal safety certification for products; various explosion-proof designs such as intrinsically safe, flameproof, and encapsulated types can be employed. In addition, the equipment must also undergo performance tests to meet the special underground coal mine environment. https://pic3.zhimg.com/80/v2-3cf920627539f95be2c9ebf0512780ea_720w.jpg For more information, keep following us!
