IEC 61935-1:20 19规定了布线参数的参考测量程序以及测量ISO/IEC 11801中确定的布线参数的现场测试仪精度要求。本标准中对ISO/IEC 11801的引用是指ISO/IEC 11801或等效布线标准。 当电缆组件由符合IEC 61156系列标准的电缆和IEC 60603-7系列标准或IEC 61076-3-104、IEC 61076-3-110、IEC 61076-2-101和IEC 61076-2-109中规定的连接硬件构成时，本国际标准适用。如果电缆和/或连接器不符合这些标准，则可能需要额外的测试。与上一版相比，此版本包括以下重大技术变更: a)上部频率上升到2 000 MHz； b)它引入了新级别的现场测试仪（VI级至2 000 MHz）； c)对VI级测试仪的误差模型和要求进行了改进和更新。

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 2 000 MHz;
b) it introduces a new level of field tester (level VI to 2 000 MHz);
c) error models and requirements for level VI testers are improved and updated.
