This International Standard establishes minimum requirements and general rules on marking electric equipment with ratings and other characteristics to enable the proper and safe selection and installation of electric equipment related to any supply of electricity. The object of this document is to: • provide general requirements for the marking of the characteristics related to any supply system, such as voltage, current, frequency and power, without any restrictions;• provide technical committees with uniform methods for the marking of electrical ratings of products. This document is primarily intended for application by technical committees when specifying minimum markings of ratings related to any electrical supply of equipment, sub-assemblies and components, but it is also for application by product manufacturers for marking their products.Cross References:ISO 80000 (all parts)IEC 80000 (all parts)EN 60529:1991/A2:2013EN 60529:1991/A1:2000EN 60529:1991/AC:2016-12EN 60529:1991/A2:2013/AC:2019-02EN 61140:2016EN 61082-1:2015EN 60529:1991IEC 61082-1:2014EN 60445:2017ISO 7000:2019ISO 80000IEC 60617IEC 60417EN 80000ISO 7000IEC 60445EN ISO 80000IEC 80000IEC 60027 (all parts)IEC 61140IEC 60529IEC 60027ISO/IEC Guide 99:2007ISO/IEC Guide 51EN 60068-2-70EN 60038IEC Guide 108IEC 60038IEC 60068-2-70All current amendments available at time of purchase are included with the purchase of this document.
