The release status of previous versions of this document and the documents it replaces are as follows. ---First published as GB/T 22264.4-2008 in.2008; --- This is the first revision.IntroductionInstalled digital display electrical measuring instruments are installed in various distribution cabinets and distribution boxes, and are widely used in industrial and mining enterprises, electric power, metallurgy, chemical industry, In fields such as energy, medical care, and transportation, the application scenarios continue to expand. GB/T 22264 series standards have been promulgated and used for more than 10 years. And market changes, the standard can no longer adapt to the development of technology and user needs. GB/T 22264 aims to standardize the technology of installed digital display electrical measuring instruments by combining the latest product technology and user needs at home and abroad. Specifications and safety requirements, and put forward corresponding test methods, to provide a product specification for manufacturers and users of such electrical measuring instruments The specification reflects most of the requirements of the product ordering technical specifications. GB/T 22264 is proposed to be composed of the following 8 parts. --- Part 1.Definitions and general requirements. The purpose is to establish the definitions and common enquiries. --- Part 2.Special requirements for ammeters and voltmeters. The purpose is to develop special requirements for ammeters and voltmeters. --- Part 3.Special requirements for power meters and reactive power meters. The purpose is to formulate special requirements for power meters and reactive power meters. --- Part 4.Special requirements for frequency tables. The purpose is to develop special requirements for frequency tables. --- Part 5.Special requirements for phase meters and power factor meters. The purpose is to formulate special requirements for phase meters and power factor meters. --- Part 6.Special requirements for insulation resistance meters. The purpose is to formulate special requirements for insulation resistance meters. --- Part 7.Special requirements for multi-function instruments. The purpose is to formulate special requirements for multi-function instruments. --- Part 8.Test methods. The purpose is to standardize the test methods for installed digital display electrical measuring instruments. In recent years, the international safety requirements for products have become more and more stringent. This revised standard, combined with IEC 61010-1.2010 and GB/T 17215.211-2021 changed the safety-related content, clarified the terms of use, and improved product safety performance.
