Full Description
IEC 61935-1:2019 specifies reference measurement procedures for cabling parameters and the requirements for field tester accuracy to measure cabling parameters identified in ISO/IEC 11801. References in this standard to ISO/IEC 11801 mean ISO/IEC 11801 or equivalent cabling standards. This International Standard applies when the cable assemblies are constructed of cables complying with the IEC 61156 family of standards, and connecting hardware as specified in the IEC 60603-7 family of standards or IEC 61076-3-104, IEC 61076-3-110, IEC 61076-2-101 and IEC 61076-2-109. Where cables and/or connectors do not comply with these standards, then additional tests may be required. This edition includes the following significant technical changes with respect to the previous edition:a) the upper frequency goes up to 1 000 MHz;
b) test methods are now included for exogenous (alien) crosstalk;
c) a new Annex A has been added for uncertainty and variability of field test results.
