    Abstract - (Show below) - (Hide below)

    Applicable to resistors intended for use as laboratory d.c. resistors (hereinafter referred to as 'resistors') comprising single or multiple resistors of accuracy Classes 0.0005 ...0.2 (5 ppM...2 000 ppM) and single or multi-decade resistors or accuracy Classes 0.0005...5(5 ppM...50 000 ppM). Recommendation does not apply to resistors used on alternating current or on pulsed currents, resistors which are intended for use solely as permanent mounted circuit components, series resistors and shunts which are considered as accessories of electrical measuring instruments in the relevant IEC publications.
