IEC 61156-4:2009

IEC 61156-4:2009 is the technical reference for multicore and symmetrical pair/quad cables for digital communications, with a specific focus on riser cables and sectional specification requirements. It is relevant when selecting, evaluating, or documenting cabling intended for vertical building runs and similar communication infrastructure where consistent performance and installation suitability matter. For engineering teams, laboratories, and procurement reviewers, IEC 61156-4:2009 supports documented evaluation, technical validation, and conformity assessment by defining a recognized basis for product comparison and compliance workflows.

What is IEC 61156-4:2009?

IEC 61156-4:2009 forms part of the IEC 61156 series and addresses multicore and symmetrical pair/quad cables used in digital communications. As a sectional specification, it is intended to help define the product characteristics and performance-related expectations for riser cable applications rather than general-purpose cabling. In practice, it is useful for technical review, specification alignment, and quality workflows where cable selection must be checked against a structured compliance reference. The edition and publication date provide context for controlled engineering documentation and procurement records.

Applications of IEC 61156-4:2009

This reference is commonly relevant to communication cabling used in building riser routes, structured cabling projects, and other installations where cables extend between floors or equipment spaces. It may also be used by manufacturers preparing product documentation, test laboratories performing verification activities, and integrators comparing cable options during product evaluation. Because the title focuses on digital communications and symmetrical pair/quad constructions, the document is particularly useful in technical assessment and testing workflows for network infrastructure and related electrical equipment.

Why is IEC 61156-4:2009 important?

IEC 61156-4:2009 helps reduce ambiguity when cables are selected, tested, or specified for riser applications. A clear sectional specification supports consistency in testing, procurement review, and regulatory preparation by giving stakeholders a common basis for engineering validation and conformity assessment. It can also assist with risk management by improving comparability across cable products and supporting documentation for quality assurance. For organizations working to maintain operational consistency, the reference is a practical tool for technical compliance and controlled decision-making.
