Winding Wires Springiness Test Apparatus
Winding Wires Springiness Test Apparatus
- Detail
- Parameters
1. Introduction
The winding wires springiness test apparatus is designed according to IEC60851-3 clause 5.2 figure 1 and figure 2 and GB/T4074.3 clause 5.2. It’s used to test the springiness of the round wire with a nominal conductor diameter from 0.080mm up to and including 1.600mm.
Principle:
A straight piece of wire is wound five times around a mandrel with a diameter and under a tension applied to the wire as specified in the relevant standard. The reading of the angle by which the end of the five turns recoils is the measure of springiness.
