CAN/CSA-C22.2 No. 61241-4:12

1 Scope The requirements of the IEC 61241 series of Standards cover protection techniques with respect to dust explosion and layer ignition hazards only. The CAN/CSA-C22.2 No. 61241 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. The requirements contained in this Standard are supplementary to those in CAN/CSA-C22.2 No. 60079-0. Note 1A: Currently, the IEC 61241 series of Standards is being converted (merged) into the IEC 60079 series of Standards. Some Standards relevant to combustible dust environments will be under the IEC 61241 series or under the IEC 60079 series, depending on the scheme of progress.
