IEC 60151-13:1966 pdf download – 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.
IEC 60151-13:1966 is a technical standard that describes methods for measuring the emission current from hot cathodes in high-vacuum electronic tubes and valves. Its main purpose is to provide a consistent way to evaluate how effectively a hot cathode emits electrons, which is a critical factor in the operation and performance of vacuum tubes.
The document focuses on measurement procedures, test conditions, and electrical arrangements used to determine emission current accurately. Since emission current reflects the cathode’s ability to supply electrons into the tube structure, it is an important indicator of tube health, quality, and operating capability. By standardizing this measurement, the document helps ensure that results are repeatable and comparable across different laboratories and manufacturers.
This standard is especially relevant in the testing and characterization of high-vacuum tubes and valves used in radio, audio, industrial, and laboratory equipment. It supports quality control, product evaluation, and technical research by giving engineers a common reference for emission testing. The methods described also help reduce differences caused by varying equipment or test setups.
For SEO, useful keywords include IEC 60151-13:1966, emission current, hot cathode measurement, electronic tubes, valve testing, high-vacuum tubes, and electrical properties of electronic tubes. In summary, this document defines standardized methods for measuring hot cathode emission current in high-vacuum electronic tubes and valves, helping to ensure accurate, reliable, and comparable test results.
