IEC 61097-2:2021/COR1:2021

IEC 61097-2:2021/COR1:2021 is a corrigendum linked to the parent reference IEC 61097-2:2021, providing a targeted modification to the requirements for Cospas-Sarsat EPIRB emergency position indicating radio beacons operating on 406 MHz. For engineering, testing, and procurement teams, it helps ensure the technical document set reflects the corrected operational and performance requirements, methods of testing, and required test results associated with global maritime distress and safety system equipment. IEC 61097-2:2021/COR1:2021 is relevant where documented evaluation, conformity assessment, and compliance workflows depend on using the most accurate version of the governing requirements.

Overview of IEC 61097-2:2021/COR1:2021

This corrigendum supports the technical framework for EPIRB equipment intended for maritime distress alerting through the Cospas-Sarsat system. As a modifying reference rather than a standalone requirement set, it is typically used alongside IEC 61097-2:2021 during technical review, verification activities, and regulatory preparation. The document is important where procurement specifications, test plans, or certification files must align with the corrected provisions affecting operational behavior, performance criteria, and related laboratory evaluation. It helps maintain consistency in engineering documentation and technical validation.

Compliance applications of IEC 61097-2:2021/COR1:2021

Organizations involved with EPIRB design, product evaluation, test laboratory work, or maritime compliance review may use this corrigendum to confirm that their working documentation matches the corrected parent standard. It is especially relevant for verification activities covering operational performance and test-result interpretation for 406 MHz distress beacons. In quality workflows, it may support revision control, conformity assessment preparation, and risk management for systems that depend on reliable distress signaling equipment. It is also useful when comparing supplier documentation against the approved compliance reference.

Importance of compliance with IEC 61097-2:2021/COR1:2021

Using the corrigendum alongside the parent document helps reduce the risk of relying on superseded or incomplete requirements during engineering validation and certification work. For safety-related maritime equipment, even a targeted correction can affect testing consistency, procurement review, and operational consistency across product records and verification reports. It supports clearer conformity assessment, more dependable technical assessment, and stronger assurance that the final compliance package reflects the intended requirements for distress beacon performance and testing. That makes it a practical control point in regulated documentation management.
