1. SCOPE This standard applies only to newly manufactured electromechanical watt-hour meters of accuracy classes 0, 5, 1 and 2, for the measurement of alternating current electrical z active energy in 50 Hz or 60 Hz networks and it applies to their type tests only. It applies only to electromechanical watt-hour meters for indoor and outdoor application consisting of a measuring element and registers) enclosed together in a meter case. It also applies to operation indicators) and test output(s). If the meter has a measuring element for more than one type of energy (multienergy meters), or when other functional elements, like maximum demand indicators, electronic tariff registers, time switches, ripple control receivers, data communication interfaces, etc. are enclosed in the meter case, then the relevant standards for these elements also apply.
