This part of IEC 60352 is applicable to spring-clamp connections made with stripped wire without further preparation: - solid conductors of 0,32 mm to 3,7 mm nominal diameter (0,08 mm2 to 10 mm2 cross-section), or - stranded conductors of 0,08 mm2 to 10 mm2 cross-ssection, or - flexible conductors of 0,08 mm2 to 10 mm2 cross-section according to IEC 60228 or IEC 60189-9 for use in telecommunication equipment and in electronic devices employing similar techniques. Information on materials and data from industrial experience is included in addition to the test procedures to provide electrically stable connections under prescribed environmental conditions. The object of this part of IEC 60352 is to determine the suitability of spring-clamp connections under specified mechanical, electrical and atmospheric conditions.
