From the International Electrotechnical Commission webstore:
“IEC 60512-28-100:2013 specifies the test methods for transmission performance for IEC 60603-7 and IEC 61076-3 series connectors up to 1 000 MHz. It is also suitable for testing lower frequency connectors; however the test methodology specified in the detailed specification for any given connector remains the reference conformance test for that connector. The test methods provided here 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. For the coupling attenuation, see IEC 62153-4-12.”
