Scope

This part of IEC 60352 is applicable to solderless crimped connections made with:

– appropriately designed uninsulated closed crimp barrels,

– stranded and flexible copper wires of nominal cross-sectional area above 10 mm2 up to 300 mm2 (included), or

– solid copper wires of diameter above 3,7 mm up to 19,8 mm (included),for use in electrical and electronic equipment and devices.

NOTE 1 The above minimum and maximum diameters of solid wires (class 1) are in line with IEC 60228:2023 Table C.1 (informative).

NOTE 2 Closed crimp barrels are usually part of removable crimp contacts for single pole or multipole electrical connectors, terminal ends, or splices.

It is read in conjunction with IEC 60352-2:2024, of which it retains the structure and clause numbering. It complements IEC 60352-2:2024 for crimped connections made with copper conductors only.

This document complements IEC 60352-2:2024 by extending its principles and requirements to applications with larger cross-sections, typically with continuous high currents and power levels. These conditions place higher demands on contact resistance and electrical stability. The suitability of such connections is evaluated under specified mechanical, electrical and environmental conditions.

Information on the materials and data from industrial experience is included in addition to the test procedures to provide electrically stable connections under prescribed environmental conditions.

This part of IEC 60352 is not intended to be applicable to crimping of coaxial cables.

The object of this part of IEC 60352 is to determine the suitability of solderless crimped connections as described above, under specified mechanical, electrical and environmental conditions and to provide a means of comparing test results when the tools used to make the connections are of different designs or manufacture.
