BS EN IEC 60352-9:2024 PDF

1   Scope

This part of IEC 60352 covers ultrasonically welded connections and includes requirements, tests and practical guidance information. This document covers ultrasonically welded connections made with stranded or flexible wires (class 2, 5 or 6 per IEC 60228) of copper or copper alloy, as well as of aluminium or aluminium alloy. These welded metal-to-metal connections shall employ wires with cross-sectional area of 0,08 mm 2 to 160 mm 2 and shall not exceed a total cross-sectional area, in case of wire bundle, of 200 mm 2 . For aluminium or aluminium alloy wires, the minimum required cross-sectional area is 2,5 mm 2 . Additionally, information on materials, data from industrial experience and test procedures are included to ensure electrically stable connections under prescribed environmental conditions. Lastly, this document aims to achieve comparable results when using ultrasonic welding equipment with similar performance and specifications as specified by the termination manufacturer.

NOTE Figures in this document show examples of possible solutions of ultrasonically welded connections of rectangular shape, but solutions are not restricted to the shape displayed.
