Details

IEC 61156-7:2023 is available as IEC 61156-7:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61156-7:2023 specifies cables that can be used for various communication systems as well as for analogue systems, such as video, that exist or are under development and which may use as many as four pairs simultaneously. In this sense, this sectional specification provides the cable characteristics required by system developers to evaluate new systems as well as to enhance present systems. It covers a cable having four individually screened (S/FTP) pairs. The cable can be provided with a common screen over the cable core. This second edition cancels and replaces the first edition published in 2003 and Amendment 1:2012. This edition includes the following significant technical changes with respect to the previous edition:
a. align clauses with IEC 61156-1:2023,
b. remove the clause related to screening attenuation as it is no longer a test to be performed (replaced by coupling attenuation),
c. replace the IEC 62153-4-2 method (injection clamp) with IEC 61156-4-5 (absorbing clamp) for coupling attenuation measurement to be consistent with all other parts of the IEC 61156 series,
d. include IEC 62153-4-9 test method (triaxial) for coupling attenuation measurement to be consistent with all other parts of the IEC 61156 series,
e. incorporate the blank detail specification.
