This Recommendation is based on current practice on the measurement of spurious and unwanted electrode currents. It should not be regarded as a Recommendation in the sense of a standard, because a more detailed description of the measuring methods is needed if measuring on the basis of these principles have to be comparable within definite tolerances. This Recommendation does not apply to gasfilled tubes or valves.
