psBAS IEC 61935-1:2024

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.<br /> 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:<br /> a) the upper frequency goes up to 2 000 MHz;<br /> b) it introduces a new level of field tester (level VI to 2 000 MHz);<br /> c) error models and requirements for level VI testers are improved and updated.
