IEC 60512-27-100:2011规定了高达500 MHz的IEC 60603-7系列连接器传输性能的测试方法。如果低频连接器满足详细规范和本标准的要求，它也适用于测试它们。 提供的测试方法有: -插入损耗， -回波损耗， -近端串扰(NEXT)， -远端串扰(FEXT)， -横向转换损耗(TCL)和 -横向转换传输损耗(TCTL)。传递阻抗（Zt）测试参见IEC 60512-26-100，耦合衰减参见IEC 62153-4-12。

IEC 60512-27-100:2011 specifies the test methods for transmission performance for IEC 60603-7 series connectors up to 500 MHz. It is also suitable for testing lower frequency connectors if they meet the requirements of the detail specifications and of this standard. The test methods provided are:
- insertion loss,
- return loss,
- near-end crosstalk (NEXT),
- far-end crosstalk (FEXT),
- transverse conversion loss (TCL) and
- transverse conversion transfer loss (TCTL). For the transfer impedance (Zt) test, see IEC 60512-26-100 and for the coupling attenuation, see IEC 62153-4-12.
