About This Item
IEC 61992-4:2006/AMD1:2015 is the amendment reference for Amendment 1 - Railway applications - Fixed installations - DC switchgear - Part 4: Outdoor d.c. disconnectors, switch-disconnectors and earthing switches. It is relevant for teams reviewing railway electrification equipment where outdoor direct-current switching and isolation functions must be documented, assessed, and maintained with care. As a supporting document connected to IEC 61992-4:2006, it helps engineers, procurement teams, and compliance specialists track updated requirements within a technical review or conformity assessment workflow.
Overview of IEC 61992-4:2006/AMD1:2015
This amendment updates the parent document for outdoor d.c. disconnectors, switch-disconnectors, and earthing switches used in railway fixed installations. In practice, IEC 61992-4:2006/AMD1:2015 is used as a compliance reference when evaluating equipment intended for DC traction infrastructure, where switching, isolation, and earthing functions must be addressed consistently. It is most useful when a project requires controlled technical documentation, design review, or verification activities aligned with the underlying railway application scope.
Compliance applications of IEC 61992-4:2006/AMD1:2015
Organizations may use this amendment when preparing specifications, reviewing supplier documentation, or checking whether outdoor DC switching equipment remains aligned with the parent railway fixed-installation requirements. It is especially relevant in engineering documentation, product evaluation, and laboratory or site-based technical validation where disconnectors, switch-disconnectors, and earthing switches are part of the installation. IEC 61992-4:2006/AMD1:2015 can also support procurement decisions by clarifying which technical document governs the current compliance workflow.
Importance of compliance with IEC 61992-4:2006/AMD1:2015
Using the amendment together with the parent part helps reduce risk during design approval, testing, and operational acceptance. For railway electrification assets, consistent documentation supports safety, interoperability, and more predictable performance criteria across engineering teams and contractors. It also helps align conformity assessment preparation with the correct revision set, which is important for quality assurance, technical validation, and regulatory preparation. In procurement and maintenance workflows, it can prevent specification drift and support more reliable technical assessment.
