scope:

The object of this Recommendation is to standardize a method of measurement and associated test conditions for use in the determination of the magnitude of current noise generated in fixed resistors, so as to make possible the comparison of the results of measurements. Limiting values of the magnitude of current noise for acceptable performance are not specified. It constitutes a description of the measurement system and procedures recommended for use in assessing the "noisiness", or magnitude of current noise, generated in fixed resistors of any given type. The method of measurement described in this Recommendation applies to all classes of fixed resistors used in circuits when current noise is critical, e.g. in some low-signal-level audio and other low-frequency circuits. It is not intended as a genreal specification reruirement.
