Annotation of standard text ČSN EN IEC 62052-11-ed.2 (356134):
This part of IEC 62052 specifies requirements and associated tests, with their appropriate conditions for type testing of AC and DC electricity meters. This document details functional, mechanical, electrical and marking requirements, test methods, and test conditions, including immunity to external influences covering electromagnetic and climatic environments. NOTE 1 - For other general requirements, such as safety, dependability, etc., see the relevant IEC 62052 or IEC 62059 standards. For accuracy requirements and other requirements specific to class indices, see the relevant IEC 62053 standards. This document applies to electricity metering equipment designed to: - measure and control electrical energy on electrical networks (mains) with voltage up to 1 000 V AC, or 1 500 V DC; NOTE 2 - For AC electricity meters, the voltage mentioned above is the line-to-neutral voltage derived from nominal voltages. See IEC 62052-31:2015, Table 7. NOTE 3 - For meters designed for operation with LPITs, only the metering unit is considered a low voltage device. If the LPITs are rated for voltages exceeding 1 000 V AC, or 1 500 V DC, the combination of the metering unit and LPITs is not a low voltage device. - have all functional elements, including add-on modules, enclosed in, or forming a single meter case with exception of indicating displays; - operate with integrated displays (electromechanical or static meters); - operate with detached indicating displays, or without an indicating display (static meters only); - be installed in a specified matching sockets or racks; - optionally, provide additional functions other than those for measurement of electrical energy
