About This Item
IEC 61156-11:2023/AMD1:2025 provides Amendment 1 to the technical framework for multicore and symmetrical pair/quad cables used in digital communications, with a focus on symmetrical single pair cables for horizontal floor wiring and transmission characteristics up to 1,25 GHz. As a supporting document linked to IEC 61156-11:2023, it is relevant when teams need to track updates affecting engineering documentation, technical review, procurement checks, and conformity assessment. The amendment helps maintain alignment between design, testing, and compliance workflows for structured cabling applications.
IEC 61156-11:2023/AMD1:2025 standard overview
This document functions as a modifying reference to the parent specification IEC 61156-11:2023 rather than a standalone cable specification. It is intended for situations where engineers, laboratories, and compliance teams must evaluate the amended requirements or clarifications affecting symmetrical single pair cables for digital communications in horizontal floor wiring. In practical terms, IEC 61156-11:2023/AMD1:2025 supports technical validation, documented evaluation, and consistency in acceptance criteria for cable-related engineering and testing workflows.
Applications of IEC 61156-11:2023/AMD1:2025
IEC 61156-11:2023/AMD1:2025 is typically used in structured cabling programs, product evaluation, and laboratory evaluation for communication cables installed in building floor wiring systems. It may be consulted during specification review, supplier qualification, and verification activities where symmetrical single pair cabling must be assessed against the amended technical basis. The reference is also useful for teams preparing technical documentation, updating compliance workflows, or confirming that cable selections remain aligned with the parent document and related performance expectations.
Why IEC 61156-11:2023/AMD1:2025 matters
For organizations responsible for electrical and communications infrastructure, this amendment helps reduce risk by keeping technical requirements, test interpretation, and procurement decisions aligned with the current normative record. It supports operational consistency when cables are being evaluated for interoperability, performance criteria, and quality assurance purposes. In compliance workflows, IEC 61156-11:2023/AMD1:2025 can be important for conformity assessment preparation, especially where technical documentation must reflect the latest amendment to the parent specification.
