IEC 60169-9:1978/AMD1:1996 is a supporting amendment to the parent document IEC 60169-9:1978, addressing radio-frequency connectors with an inner diameter of the outer conductor of 3 mm, screw coupling, and a characteristic impedance of 50 ohms (Type SMC). For engineering teams and procurement workflows, it is relevant where connector definition, product selection, and technical documentation need to align with a controlled reference. The amendment should be read as part of the parent technical framework, especially during documented evaluation and conformity assessment activities.

What is IEC 60169-9:1978/AMD1:1996?

This publication functions as an amendment to the original connector specification rather than a standalone product standard. It is intended to modify or clarify requirements associated with the 3 mm R.F. coaxial connector type identified as SMC, including the screw-coupling interface and 50 ohm characteristic impedance described in the title. In practice, it supports technical review, engineering documentation, and compliance workflows by helping users work from the correct revision of the parent reference when evaluating connector compatibility or quality assurance records.

Applications of IEC 60169-9:1978/AMD1:1996

IEC 60169-9:1978/AMD1:1996 is relevant in RF component procurement, connector specification control, laboratory evaluation, and build documentation where Type SMC interfaces are used. It may be consulted during product validation, incoming inspection, or supplier review to confirm that drawings, test plans, and part descriptions are aligned with the amended reference. The document is also useful in operational consistency checks where matching connector geometry and impedance are important for reliable electrical equipment integration and testing workflows.

Why is IEC 60169-9:1978/AMD1:1996 important?

Using the amended reference helps reduce technical ambiguity when managing connector selection, qualification, and regulatory preparation. For organizations that rely on RF interconnects, a clearly identified supporting document improves interoperability checks, testing consistency, and engineering validation. It also supports risk management by helping teams avoid using outdated or incomplete documentation during conformity assessment or procurement review. In quality workflows, the amendment can be an important control point for maintaining accurate technical records tied to the parent connector specification.

• Supports controlled use of the Type SMC connector reference within a documented engineering specification
• Helps align procurement and supplier documentation with the amended parent standard
• Useful for laboratory evaluation, product verification, and connector conformity assessment
• Assists technical teams in maintaining consistency across RF interface and testing records
