IEC 60169-20:1985 defines requirements for radio-frequency connectors, specifically R.F. coaxial connectors with an inner diameter of outer conductor of 2.08 mm and screw coupling, with a characteristic impedance of 50 ohms (Type SSMC). As a technical reference, it supports engineering documentation, product evaluation, and conformity assessment where connector interface consistency matters. For procurement, test planning, and compliance review, IEC 60169-20:1985 helps teams align selected components with a clearly identified connector form factor and performance context.

Overview of IEC 60169-20:1985

This document addresses a defined coaxial connector type within the IEC 60169 series, giving a focused specification for the Type SSMC interface. Its likely purpose is to support dimensional and interface compatibility, helping manufacturers, laboratories, and system integrators evaluate whether a connector design matches the intended 50 ohms RF application. In technical review and verification activities, the reference is useful for comparing product data, preparing acceptance criteria, and maintaining operational consistency across RF assemblies.

Compliance applications of IEC 60169-20:1985

IEC 60169-20:1985 is relevant in workflows involving RF connector selection, laboratory evaluation, and hardware qualification for coaxial interconnects. It may be used when reviewing connectors for measurement equipment, test fixtures, communication subsystems, or other electronic assemblies that depend on controlled impedance and repeatable coupling. In procurement and compliance workflows, the reference helps teams document the intended connector type, reduce substitution risk, and support technical assessment before installation, test, or release.

Importance of compliance with IEC 60169-20:1985

Using IEC 60169-20:1985 as a compliance reference can improve interchangeability, reduce interface mismatches, and support reliable mating between RF components. That is important for engineering validation, quality assurance, and conformity assessment preparation, especially where connector performance affects measurement stability or system integrity. For organizations managing documented evaluation and technical validation, the reference provides a clearer basis for specification control, supplier review, and risk reduction across RF hardware workflows.
