IEC 60512-23-3:2018. defines a standard test method for measuring the shielding effectiveness SE of a shielded connector, or of a connector not provided with integral shield once fitted with a shielding accessory and terminated with a screened cable. The complete assembly has a continuous 360° shielding capability throughout its length. This test method can be applied to shielded connectors and to connector accessories with shielding capability. The following different connector designs can be tested:
- circular connectors;
- rectangular connectors;
- connectors for printed boards;
- connector shielding accessories.
This test method utilizes the principle that the intrinsic shielding property of the connector/ accessory/cable assembly is its surface transfer impedance ZT which can be expressed as the longitudinal voltage inside the shield, relative to the current flow on the outside shell. This test is also suitable for measuring the shielding effectiveness of a connector fitted with triaxial contacts terminated with shielded, twisted pair cables, as used in data bus systems. This second edition cancels and replaces the first edition, published in 2000. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) an introduction has been added to provide some guidance to this document in view of concurrent test method 23g in the same family;
b) the frequency range for which this test method is considered reliable moved from 1 GHz to 3 GHz, to be consistent with Figure 7 (unchanged) and current industry practice and need;
c) update to IEC 62153-4-6:2017 of former normative reference IEC 60096-4-1:1990, withdrawn and incorrect (should have been IEC 61196-1:1995, also withdrawn);
d) update to current subclause numbers of IEC 62153-4-6:2017 what were the previous subclause numbers referenced in IEC 61196-1:1995 (wrongly attributed to IEC 60096-4-1:1990). For immediate understanding the title of these subclauses has been added;
e) alignment of title to the current scope of SC 48B (connectors) and inclusion of electrical equipment as target application of said connectors (per current scope of TC 48) and explicit reference to the method – line injection – for the measurement of transfer impedance;
f) symbols SE for shielding effectiveness and ZT for surface transfer impedance added throughout the document;

IEC 61076-3-110:2016 This detail specification covers mechanical, electrical and environmental requirements and electrical transmission requirements for frequencies up to 3 000 MHz. These connector's transmission requirements are specifically intended for specific pairs of contacts, which are separated from the other pairs of contacts, such as by means of individual pair shields within the connector. These connectors are similar to, intermateable with, and intended to be used with the IEC 60603-7 series connectors. The IEC 60603-7 series connectors are typically used in ISO/IEC 11801 balanced cabling systems. The ISO/IEC 11801 balanced cabling systems are organized by categories according to frequency range and by basic cabling component types, e.g. according to shielding configurations. A primary common feature among the IEC 60603-7 series connectors is backward compatibility to lower frequency categories. The IEC 61076-3-110 series connectors are backward compatible with IEC 60603-7-7, IEC 60603-7-71 and IEC 60603-7-82 connectors. The IEC 61076-3-110 series connectors are not backward compatible with some IEC 60603-7 series connectors. Key words: Connectors, Free and Fixed Data Transmission, 3000 MHz
