IEC EN 60352-7 Solderless Connections - Part 7: Spring Clamp Connections - General Requirements and Test Methods

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60352-7 testing. This part of IEC EN 60352 applies to spring clamp connections made with stripped wire without further preparation:

• Single core conductors with nominal diameter of 0,32 mm to 3,7 mm (0,08 mm² to 10 mm² cross section);
• Stranded conductors with a cross section of 0,08 mm² to 10 mm²;
• Flexible conductors with cross section from 0,08 mm² to 10 mm².

In addition to test procedures, information on materials and data from industrial experience are included to ensure electrically stable connections under anticipated environmental conditions. The purpose of this part of IEC EN 60352 is to determine the suitability of spring clamp connections under specified mechanical, electrical and atmospheric conditions.

The link will be handled carefully and skillfully in accordance with current good practice. Tools should be used and checked, if necessary, in accordance with the manufacturer's instructions.

Spring clamp terminations should be designed so that the spring clamp parts generate sufficient force to create a reliable connection.

In a spring clamp connection device, each conductor must be clamped individually. Openings for the use of a tool intended to aid in the insertion or removal of the conductor must be clearly distinguishable from the conductor entry hole.

The suitability of the spring clamp connection depends on the termination dimensions as well as the properties of the materials used. Dimensions should be chosen to match the cable or cable spacing for which the termination is designed.
