EN 62053-11 applies to newly manufactured electromechanical watt-hour meters of accuracy classes 0.5, 1, and 2. It specifies the requirements for type testing these meters, which measure alternating current electrical active energy in 50 Hz or 60 Hz networks. The standard covers meters designed for both indoor and outdoor use, including their measuring elements, registers, operation indicators, and test outputs, all enclosed in a single meter case.
