CAN/CSA-C22.2 No. 60079-31:12

1 Scope The requirements of the IEC 60079 series of Standards cover protection techniques with respect to gas explosion, dust explosion, and layer ignition hazards only. The CAN/CSA-C22.2 No. 60079 series of Standards (based on the adoption of corresponding IEC Standards) is to be used in conjunction with other applicable Part II Standards containing the appropriate electrical safety requirements for general use equipment. General requirements for electrical products are as indicated in CSA C22.2 No. 0. Note 2A: The IEC 61241 series of Standards, covering dust-explosion and dust-layer combustion, is being converted (merged) into the IEC 60079 series of Standards. Due to the publication schedules, some IEC 61241 and IEC 60079 Standards may not be fully aligned.
