ISO/EC 14776-121:2010（E）规定了互连的性能要求，并将覆盖范围扩展到完整组装的互连，包括连接器、均匀散装电缆和非均匀散装电缆。本文描述了所有类型的无源互连的语法和框架。其中包括为确定几类散装电缆、各种组装互连和印刷电路板设计是否符合性能要求而进行电气测量的方法。规定了测量方法的细节，以尽量减少不同电气测试实验室测量结果的差异。详细信息包括校准、夹具和样品制备、设备、测量程序和数据输出格式。

ISO/EC 14776-121:2010(E) specifies the performance requirements of the interconnect and expands the coverage to the complete assembled interconnect including connectors, uniform bulk cable, and non-uniform bulk cable. A syntax and framework is described for all types of passive interconnect. The methodology for performing the electrical measurements required to determine compliance with the performance requirements for bulk cable of several types, various assembled interconnects and printed circuit board designs is included. Details of the measurement methodology are specified to minimize the difference in measured results from different electrical testing laboratories. Details include calibration, fixturing and sample preparation, equipment, measurement procedure and data output format.
