IEC 60521 (1988-03) Class 0.5, 1 and 2 alternating-current watthour meters Applies only 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 only. This publication supersedes IEC 60043 (1960), 60170 (1964) and 60280 (1968). ---- Patrick Lawler plaw...@west.net On Mon, 29 Apr 2002 10:55:57 -0400, Ned Devine <ndev...@entela.com> wrote: >I can help much, but, for this paragraph, the rationale at the back of the >standard states that "Annex AAA of the Collateral Standard IEC 60601-1-2 >states that the limits and methodology are under consideration by technical >committee 77.
