About This Item
IEEE P1349-2021/Cor 1/D1.3, Apr 2022 is an IEEE approved draft corrigendum for the guide on applying electric machines in Zone 2 and Class I, Division 2 hazardous locations. It is relevant where equipment must be selected and installed with attention to ignition risk, enclosure suitability, and operating conditions in potentially hazardous atmospheres. In this technical context, the document helps align engineering decisions with safer machine application practices and more consistent compliance planning.
IEEE P1349-2021/Cor 1/D1.3, Apr 2022 overview
This standard product page covers IEEE P1349-2021/Cor 1/D1.3, Apr 2022, a corrigendum tied to the guide for electric machines used in hazardous classified locations. Its purpose is to clarify or correct draft guidance related to machine application in Zone 2 and Class I, Division 2 environments, where flammable gases or vapors may be present under abnormal conditions. For engineers and specifiers, the document supports more precise interpretation of application guidance, especially where safety and installation requirements must be matched to the site classification.
Typical use cases
This technical document is commonly used when evaluating motors, generators, or other electric machines intended for petroleum, chemical, processing, or industrial facilities with classified areas. It may support equipment selection, installation review, and design documentation for zones where hazardous atmospheres are not expected during normal operation but may occur occasionally. Teams responsible for power, energy, and industrial applications can use IEEE P1349-2021/Cor 1/D1.3, Apr 2022 to help compare equipment options, review enclosure concepts, and verify that application assumptions fit the location classification.
Why this standard matters
In practice, this corrigendum matters because hazardous-location projects depend on accurate and consistent guidance. Even small clarifications can affect machine selection, maintenance planning, and the way compliance evidence is assembled. Using IEEE P1349-2021/Cor 1/D1.3, Apr 2022 can help reduce ambiguity during procurement and design review, especially when different stakeholders must agree on the appropriate application of electric machines. It also supports risk reduction by improving the technical basis for decisions in classified areas.
