IEC 61156-1:2023

IEC 61156-1:2023 provides the core technical reference for multicore and symmetrical pair/quad cables used in digital communications. As the first part of the IEC 61156 series, it is typically used to support engineering review, procurement decisions, and conformity assessment for cabling products intended for data transmission applications. For organizations comparing cable constructions or documenting compliance, IEC 61156-1:2023 helps define the generic specification basis that underpins later product selection, verification activities, and technical evaluation.

Purpose of IEC 61156-1:2023

The purpose of IEC 61156-1:2023 is to establish the generic specification framework for multicore and symmetrical pair/quad cables in digital communication systems. It is generally used as a baseline technical document when assessing cable design, performance expectations, and product classification within the IEC 61156 series. In engineering and compliance workflows, it supports consistent technical review, documented evaluation, and alignment between design intent and procurement or testing requirements.

Compliance applications of IEC 61156-1:2023

IEC 61156-1:2023 is commonly relevant in product development, laboratory evaluation, and quality assurance for communication cables used in structured installations, control environments, and other digital interconnect applications. It may be referenced during technical validation, supplier qualification, and conformity assessment preparation when organizations need a clear baseline for cable documentation and verification. The document can also support internal compliance workflows by helping teams compare candidate products against a recognized engineering specification.

Benefits of IEC 61156-1:2023

Using IEC 61156-1:2023 can improve operational consistency by giving procurement, engineering, and testing teams a shared technical reference for multicore and symmetrical pair/quad cable requirements. That can reduce ambiguity during product evaluation, support more reliable testing workflows, and strengthen conformity assessment preparation. It is also useful for risk management, since a well-defined specification basis often helps limit documentation gaps, improve interoperability expectations, and streamline technical compliance reviews across projects and supply chains.
