I would like to ask the experts: What do Ga, Gb, and Gc mean when they are added after the explosion protection rating? What are the specific differences between them?

Article 29 of the latest **explosion protection standard GB 3836.1-2010 \"Explosive atmospheres – Part 1: Equipment – General requirements\" provides specifications for markings. Equipment protection levels: \"Ga\", \"Gb\", \"Gc\", \"Ma\" or \"Mb\""
