scope:

This part of IEC 60512-23 defines a test method which is intended to assess the screening effectiveness of screened non-circular multi-pole, electrically short, connectors by the measurement of the effective (surface) transfer impedance ZTE expressed in , using a network analyzer, for frequencies up to 1 GHz. It is based on the line injection test method according IEC 61196-1 with a specific type of injection wire, which is adapted to the shapes of connectors. Due to the specific test set-up used in the method described hereinafter the connector screen itself is not verified, but the combination of two connectors (male and female) together, i.e. the test results include the effectiveness of the screens of the two connectors and the joint between the connectors and the joints of the cable to the connector.
