scope:
This part of ISO/IEC 80079 specifies the requirements for the design and construction of non-electrical equipment, intended for use in explosive atmospheres, protected by the types of protection constructional safety "c", control of ignition source "b" and liquid immersion "k".
This part of ISO/IEC 80079 supplements and modifies the requirements in ISO 80079-36. Where a requirement of this standard conflicts with the requirement of ISO 80079-36 the requirement of this standard takes precedence.
Types of Protection "c", "k" and "b" are not applicable for Group I, EPL Ma without additional protective precautions.
The types of ignition protection described in the standard can be used either on their own or in combination with each other to meet the requirements for equipment of Group I, Group II, and Group III depending on the ignition hazard assessment in ISO 80079-36.
The requirements of the ISO/IEC 80079 series of Standards cover protection with respect to explosion hazard only. The CSA C80079 series of Standards (based on the adoption of corresponding ISO/IEC Standards) may be used in conjunction with other applicable Standards containing the appropriate electrical safety requirements for general use equipment.
