GSO IEC 60151-13:2014 Measurements of the electrical properties of electronic tubes and valves - Part 13: Methods of measurement of emission current from hot cathodes for high-vacuum electronic tubes and valves
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.
