scope:

This recommendation applies to resistors intended for use as laboratory d.c. resistors (hereinafter referred to as "resistors") comprising single or multiple resistors of accuracy Classes 0.00005...0.2 (5 ppM...2000 ppM) and single or multi-decade resistors of accuracy Classes 0.00005...5 (5 ppM...50.000 ppM). This recommendation does not apply to: - resistors which are intended for use soleley as permanent mounted circuit components; - resistors used on alternating current or on pulsed currents, - series resistors and shunts which are considered as accessories of electrical measuring instruments in the relevant IEC publications.
