Deals with the measurement (by static watt hour meters of accuracy classes 0,2 S and 0,5 S) of alternating current electrical active energy of a frequency between 45Hz to 65 Hz and to their type tests only. Applies transformer operated static meters for indoor application consisting of one or more measuring elements and registers enclosed together in the same case. Also applies to test outputs, operation indicators and meters that measure energy in both directions. Does not apply to: portable meters and meters for outdoor use; watt hour meters where the voltage across the connection terminals exceeds 600 V (line to line voltage for meters for polyphase systems); data interface to the register of the meter; reference meters.
