Applies to newly manufactured induction type watt-hour meters of accuracy classes 0.5, 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. Applies to the assembly of meters and accessories, including current transformers, when enclosed in the meter case. Does not apply to maximum demand indicators, to any kind of measuring device such as those used for telemetering electrical energy, to meters for testing purposes or to special types of watt-hour meters.
