About This Item
IEEE 1349-2021/Cor 1-2022 is a corrigendum to the IEEE guide for applying electric machines in Zone 2 and Class I, Division 2 hazardous (classified) locations, providing targeted corrections to the technical text. It is relevant where motors and related equipment must be selected, installed, and used with hazardous-location constraints in mind. For engineers and specifiers, this version helps support clearer interpretation of the guide and more reliable compliance decisions in environments where ignition risk and equipment suitability matter.
What is IEEE 1349-2021/Cor 1-2022?
This technical document is a corrigendum associated with IEEE 1349-2021, focused on the application of electric machines in less severe hazardous areas defined as Zone 2 and Class I, Division 2. The IEEE 1349-2021/Cor 1-2022 text is intended to correct or refine the underlying guidance so that readers can rely on more accurate terminology, requirements, or explanatory material. In practical terms, it supports better understanding of machine selection, installation considerations, and safe use in classified locations.
Where is IEEE 1349-2021/Cor 1-2022 used?
IEEE 1349-2021/Cor 1-2022 is used when electric machines are specified for installations where flammable gases or vapors may be present under defined hazardous-location conditions. Typical use may include motor-driven equipment, rotating machinery, and associated electrical systems in industrial facilities that classify areas as Zone 2 or Class I, Division 2. It is especially relevant during design review, equipment procurement, maintenance planning, and documentation checks for systems that must match the site’s classification and safety expectations.
Why is IEEE 1349-2021/Cor 1-2022 important?
This corrigendum matters because small technical corrections can affect how a hazardous-location guide is interpreted and applied. Using IEEE 1349-2021/Cor 1-2022 can help reduce ambiguity in design and compliance work, especially when selecting electric machines for classified areas. It supports more consistent engineering decisions, clearer procurement requirements, and better alignment between specifications and field practice. For organizations working with hazardous-location equipment, that can mean lower risk, fewer installation errors, and improved confidence in documentation.
