    Abstract - (Show below) - (Hide below)

    Resistors of accuracy classes which, in the case of single or multiple resistors is 0.0005-0.2 and for single or multi-decade resistors is 0.0005-5. Specifies the limits of intrinsic error and conditions for determination of such errors, permissible variations and further electrical and mechanical requirements.
