IEC 60079-26:2021 PDF Download

IEC 60079-26:2021 is a standard that sets out the requirements for equipment used in explosive atmospheres. The equipment covered by this standard includes those that have different levels of protection and are separated by a boundary where different levels of protection are required. This can include equipment used in areas with different types of hazardous substances, such as gases or dusts.

The standard covers both electrical and non-electrical equipment that may pose an ignition hazard. For example, if mechanical energy can be converted into a potential ignition source, an assessment is performed to identify the potential ignition hazard in accordance with ISO 80079-36. Measures are then taken to mitigate the identified hazards.

This standard also specifies requirements for combining two types of protection, each with its own equipment protection level, to achieve a higher level of protection. This allows for flexibility in designing equipment that meets the specific requirements of different hazardous areas.

It is important to note that this standard supplements and modifies the general requirements set out in IEC 60079-0. In case of any conflicts between the requirements of these two standards, the requirements of IEC 60079-26:2021 take precedence. This latest edition of the standard replaces the previous edition and includes technical revisions to improve its effectiveness.
