IEC TR 61156-1-5:2013

IEC TR 61156-1-5:2013 addresses correction procedures for the measurement results of return loss and input impedance in multicore and symmetrical pair/quad cables for digital communications. For engineering, testing, and procurement teams, it provides a technical reference for handling measurement data in a more consistent way, supporting documented evaluation and technical validation. IEC TR 61156-1-5:2013 is relevant where cable performance needs to be assessed with care, especially when repeatable testing workflows and reliable compliance evidence are important.

What is IEC TR 61156-1-5:2013?

This technical report is part of the IEC 61156 series for multicore and symmetrical pair/quad cables used in digital communications. Its focus is not on general cable construction, but on correction procedures applied to measured return loss and input impedance results. That makes it useful as a compliance reference for laboratories and manufacturers that need consistent interpretation of test data. In practice, it can support technical review, laboratory evaluation, and quality workflows where accurate measurement handling is necessary.

Applications of IEC TR 61156-1-5:2013

IEC TR 61156-1-5:2013 is typically used in cable testing environments, product evaluation programs, and conformity assessment preparation for digital communication cabling. It may be consulted by test laboratories, cable manufacturers, and engineering teams working on measurement methods for return loss and input impedance. The document is especially relevant when results must be compared, corrected, or documented in a controlled way to support operational consistency and procurement review.

Why is IEC TR 61156-1-5:2013 important?

Accurate handling of return loss and input impedance measurements can affect technical assessment, product validation, and overall compliance confidence. IEC TR 61156-1-5:2013 helps reduce ambiguity in test result interpretation, which is useful for verification activities and risk management during development or acceptance testing. It also supports better alignment between laboratories, suppliers, and buyers when engineering documentation must demonstrate consistent measurement practice and reliable performance criteria.
