This standard applies to d.c. bridges for measuring resistance. It also applies to auxiliary equipment which is a built-in part of the bridge.
This standard does not apply to bridge comparators*, nor to self-balancing bridges nor to those which employ graduations on the null detector to obtain a part of the indicated value, nor to external auxiliary equipment used with the bridge.
