EVS-EN ISO 80079-37:2016

ISO 80079-37 specifies the requirements for the design and construction of non-electrical equipment used in explosive atmospheres. The equipment is protected by the types of protection constructional safety “c”, control of ignition source “b” and liquid immersion “k”. ISO 80079-37 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 ISO 80079-37 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 international standard has been approved in Europe as EN ISO 80079-37:2016 without any changes.
