Explosion-proof mark standard note: According to the current national standard GB 3836.1-2010 "Explosive atmosphere - Part 1: General requirements for equipment" (hereinafter referred to as GB 3836.1) Chapter 29, the above-mentioned Explosion-proof mark specific notes are as follows:
Note 1: Ex is an explosion-proof mark of China and the International Electrotechnical Commission, indicating that electrical equipment meets one or more of the explosion-proof types specified in the special standards listed in Chapter 1 of GB 3836.1.
Note 2: The types of explosion-proof symbols used are as follows:
─ "d": Flameproof enclosure (corresponding to EPL Gb or Mb)
─ "e": Increased safety (corresponds to EPL Gb or Mb or Gc)
─ "ia": Intrinsically Safe (Corresponding to EPL Ga or Ma)
─ "id": Intrinsically Safe (Corresponding to EPL Gb or Mb)
─ "ic": Intrinsically Safe (corresponding to EPL Gc)
Note 3: Equipment category notation - Category I: Coal-use electrical equipment that is prone to gas generation; Category IIA, IIB or IIC: Electrical equipment for explosive gas atmospheres other than coal mines that are prone to gas generation. ─ Note 1: The equipment marking the IIB can be applied to the conditions of use of the IIA equipment. Similarly, the equipment marking the IIC can be applied to the conditions of use of the IIA and IIB equipment; therefore the explosion-proof class IIC> IIB> IIA.
Note 4: For Class II electrical equipment, the symbol for the temperature group is described in GB 3836.1 Section 5.3.2.2 “Class II Electrical Equipment” as follows:

Note 5: If applicable, equipment protection level "Ga", "Gb", "Gc", "Ma" or "Ma".
Equipment Protection Level (EPL): A fixed level of protection for equipment based on its potential to be a source of ignition and the different characteristics of explosive gas atmospheres, explosive dust environments, and mine methane explosive atmospheres.
- EPL Ma: Equipment installed in a methane explosive atmosphere in coal mines, with a "high" level of protection that is sufficiently safe to allow the equipment to operate normally, to have expected failures or rare failures, even The sudden appearance of gas can not be a source of ignition in the event that the equipment is still charged.
─ Mb (EPL Mb): The equipment installed in the methane explosive atmosphere of coal mines has a “high” level of protection, which is of sufficient safety to allow the equipment to operate during normal operation or when gas suddenly appears and the equipment is powered off. It is impossible to be a source of ignition under expected fault conditions that occur within an intervening time.
- Class E (EPL Ga): Equipment used in explosive gas atmospheres with a "high" level of protection and not a source of ignition in normal operation, expected failures, or rare failures.
- GPL (EPL Gb): Equipment for use in explosive gas atmospheres with a "high" level of protection and not a source of ignition under normal or expected failure conditions.
─ Gc grade (EPL Gc): Equipment for explosive gas atmospheres, with a "general" level of protection, not a source of ignition during normal operation, and may also take additional protective measures to ensure that the ignition source is expected to occur frequently (eg, Lamp failure) does not form an effective ignition.
- Class E (EPL Da): Equipment used in explosive dust environments with a "high" level of protection and not a source of ignition in normal operation, expected failures, or rare failures.
- Class Db (EPL Db): Equipment for use in explosive dust environments with a "high" level of protection and not a source of ignition under normal or expected failure conditions.
Class Dc (EPL Dc): Equipment for explosive dust environments, having a "normal" level of protection, not a source of ignition during normal operation, and may also take additional protective measures to ensure that the ignition source is expected to occur frequently (eg, Lamp failure) does not form an effective ignition.
According to the requirements of the current national standard GB 3836.1-2010 "Explosive atmospheres Part 1: General requirements for equipment", under the same conditions, the electrical equipment with explosion-proof signs up to the Ex d IIC T6 Gb standard shall be higher than the explosion-proof mark up to Ex. d IIB T6 Gb standard electrical equipment.
