标准摘要
Applies only to newly manufactured indoor or outdoor static watt-hour meters of accuracy classes 1 and 2, for the measurement of alternating-current electrical active energy of a frequency in the range 45 Hz to 65 Hz and to their type tests only. Does not apply to watt-hour meters where the voltage across the connection terminals exceeds 600 V, portable meters, data interfaces to the register of the meter. Acceptance tests are partially given in IEC 514.
