GB/T 5095.2509-2020 is the Chinese standard "Electromechanical components for electronic equipment - Basic testing procedures and measuring methods - Part 25-9: Signal integrity tests - Test 25i: Alien crosstalk".
Its scope clause reads: The test method specified in this part of GB/T 5095 is used to assess the proximity between the connectors installed in its installation system.
End Alien Crosstalk (ANEXT) and Far End Alien Crosstalk (AFEXT). Both modular connectors and multi-port panel connectors can be used Method to conduct experiments.
This method provides a way to test for alien (foreign) crosstalk between any two ports, and to assess the All alien crosstalk at the mouth.
This test procedure is widely applicable to all electrical connectors in electromechanical components, especially to the IEC 60603-7 series Columns and connectors described in IEC 61076-3-104, as well as other types of connectors used for data transmission. Its clauses include scope and purpose; terms and definitions.

1 Scope and purpose
The test method specified in this part of GB/T 5095 is used to assess the proximity between the connectors installed in its installation system.
End Alien Crosstalk (ANEXT) and Far End Alien Crosstalk (AFEXT). Both modular connectors and multi-port panel connectors can be used
Method to conduct experiments. This method provides a way to test for alien (foreign) crosstalk between any two ports, and to assess the
All alien crosstalk at the mouth. This test procedure is widely applicable to all electrical connectors in electromechanical components, especially to the IEC 60603-7 series
Columns and connectors described in IEC 61076-3-104, as well as other types of connectors used for data transmission.
