SJ/Z 9010.13-1987 Measurements of electrical properties of electronic tubes and valves--Part 13: Methods of measurement for emission current from hot cathodes for high-vacuum electronic tubes and valvea (English Version)
This document is based on current practice for testing hot cathode emission currents in high vacuum electron tubes. It is not intended to be a recommendation document of a standard nature, since if test results based on these principles have to be compared within defined tolerances, a more detailed description of the test method is required.
