IEC 60151-13:1966 defines a technical method for measuring the emission current from hot cathodes in high-vacuum electronic tubes and valves. It is relevant to engineering teams and laboratories that need a consistent approach for evaluating electron emission performance during test, verification, or product assessment activities. As an original document, IEC 60151-13:1966 serves as the primary reference for this measurement topic and supports disciplined technical review, documented evaluation, and conformity assessment workflows.

Purpose of IEC 60151-13:1966

The purpose of IEC 60151-13:1966 is to provide a measurement method focused on emission current from hot cathodes in high-vacuum electronic tubes and valves. In practical terms, it helps define a common technical basis for laboratory evaluation, reducing ambiguity when comparing results across equipment, test setups, or procurement specifications. For organizations handling legacy vacuum-tube technology, it can support engineering validation, quality workflows, and controlled technical assessment where repeatable emission measurements are important.

Compliance applications of IEC 60151-13:1966

IEC 60151-13:1966 may be used in testing workflows for electronic tubes and valves where emission current measurement is part of acceptance, qualification, or analytical review. It is relevant to laboratories, manufacturers, and procurement teams that need a reliable compliance reference for technical document control and evaluation of high-vacuum device performance. In regulated or specification-driven environments, it can help structure verification activities and improve consistency in measurement-based reporting.

Benefits of IEC 60151-13:1966

Using IEC 60151-13:1966 can improve testing consistency and reduce risk when emission current data is needed for engineering documentation or conformity assessment preparation. A defined measurement method supports clearer technical communication between suppliers, test laboratories, and internal reviewers, which can strengthen procurement review and product evaluation. It also helps promote operational consistency in validation programs, especially where repeatable results and traceable technical assessment are important to quality assurance.
