This Recommendation is based on current practice on the measurement of emission current from hot cathodes for high-vacuum electronic tubes and valves. 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 results on the basis of these principles have to be comparable within definite tolerances.
