About This Item
IEC 62052-21:2004 is the technical reference for electricity metering equipment (a.c.) where tariff and load control functions are involved. It is relevant to teams assessing metering devices that must operate consistently within defined test and performance expectations. For engineering, procurement, and compliance workflows, the document helps frame documented evaluation, technical review, and conformity assessment activities around equipment intended for controlled energy measurement and load management applications.
What is IEC 62052-21:2004?
This publication addresses general requirements, tests, and test conditions for tariff and load control equipment used with alternating-current electricity metering systems. In practice, IEC 62052-21:2004 is used as a compliance reference when evaluating how such equipment is expected to be checked under specified test conditions and how it should support operational consistency. Its scope is mainly relevant to performance validation, quality workflows, and technical documentation for metering-related products.
Applications of IEC 62052-21:2004
The document is commonly relevant to manufacturers, test laboratories, utilities, and procurement teams working with electricity metering and control equipment. It may be used during product evaluation, laboratory evaluation, and regulatory preparation for devices that support tariff functions or load control in a.c. metering environments. It also supports engineering documentation reviews where equipment must be compared against defined testing workflows and compliance expectations before deployment or acceptance.
Why is IEC 62052-21:2004 important?
For organizations involved in metering system development or procurement, IEC 62052-21:2004 helps establish a consistent basis for technical validation and risk management. By setting out general requirements and test conditions, it supports repeatable verification activities and reduces uncertainty during conformity assessment. That makes it useful for quality assurance, comparison of supplier documentation, and preparation for compliance checks where tariff and load control equipment must be assessed in a controlled and defensible way.
