CSA C80079-37:22

1 Scope This part of ISO/IEC 80079 specifies the requirements for the design and construction of nonelectrical 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. Les exigences des normes de la série ISO/IEC 80079 portent sur la protection en ce qui a trait au risque d’explosion uniquement. Les normes de la série CSA C80079 (basées sur l’adoption des normes ISO/IEC correspondantes) peuvent être utilisées avec d’autres normes pertinentes qui énoncent les exigences relatives à la sécurité électrique applicables au matériel d’usage général.
