IEC 60135:1961 provides a technical reference for the numbering of electrodes and the designation of units in electronic tubes and valves. For engineering teams, test laboratories, and procurement specialists, it helps establish a common identification framework that supports accurate documentation, part selection, and technical review. IEC 60135:1961 is relevant where consistent terminology and unit designation are needed to reduce ambiguity in specifications, drawings, and conformity assessment records for electronic tube and valve components.

Purpose of IEC 60135:1961

The purpose of this document is to standardize how electrodes are numbered and how units are designated in electronic tubes and valves, supporting operational consistency across technical documentation and product evaluation. In practice, that helps engineers and compliance staff interpret component references in a uniform way during verification activities, laboratory evaluation, and engineering documentation control. It is especially useful when maintaining clear relationships between design data, test records, and procurement specifications.

Compliance applications of IEC 60135:1961

IEC 60135:1961 may be used in technical assessment workflows where electronic tubes and valves are identified, specified, or compared during product validation and quality workflows. It can support purchasing review, legacy equipment documentation, and conformity assessment preparation by reducing the risk of inconsistent naming or numbering. In testing environments, the document can also help align reference designations used in reports, inspection records, and engineering specifications.

Benefits of IEC 60135:1961

Using IEC 60135:1961 can improve clarity across compliance workflows by reducing interpretation errors in component identification. That supports safer engineering decisions, more reliable technical validation, and better interoperability between design, test, and procurement records. It may also help streamline documented evaluation and risk management by making it easier to trace electrode numbering and unit designations consistently across technical files, which can be valuable during conformity assessment and quality assurance reviews.
