ISO/IEC 17982:2021 defines the technical reference for Information technology - Telecommunications and information exchange between systems - Close capacitive coupling communication physical layer (CCCC PHY). For teams evaluating close-range communication interfaces, it provides a structured basis for technical review, product evaluation, and compliance workflows. As a derived document linked to the parent reference ISO/IEC 17982, it is relevant when organizations need a controlled standard document for engineering documentation, testing preparation, or procurement review around this physical-layer communication method.

Purpose of ISO/IEC 17982:2021

The purpose of ISO/IEC 17982:2021 is to support consistent understanding of the close capacitive coupling communication physical layer used for telecommunications and information exchange between systems. In engineering and conformity assessment work, that means a clear reference for evaluating implementation expectations, interoperability considerations, and technical validation activities. It is typically useful when a project needs a documented basis for design review, laboratory evaluation, or compliance planning tied to the CCCC PHY interface and its associated communication behavior.

Compliance applications of ISO/IEC 17982:2021

ISO/IEC 17982:2021 is commonly used in testing workflows, supplier technical assessment, and conformity assessment preparation for systems that rely on close capacitive coupling communication. It may support procurement teams reviewing technical suitability, laboratories planning verification activities, and engineering groups documenting design controls for telecommunications equipment or related systems. The document can also be helpful in quality workflows where operational consistency, technical compliance, and traceable evaluation of the physical layer are important for regulated or standards-driven development programs.

Benefits of ISO/IEC 17982:2021

Using ISO/IEC 17982:2021 can improve technical alignment across design, testing, and procurement functions by giving teams a shared compliance reference for the close capacitive coupling communication physical layer. It helps reduce risk during product evaluation, supports more consistent laboratory interpretation, and can strengthen engineering validation and documentation practices. For organizations preparing for conformity assessment or internal review, the document offers a reliable basis for technical assessment, controlled verification, and clearer communication between development, test, and compliance stakeholders.
