SPRING ELONGATION TESTER
Overview of SPRING ELONGATION TESTER
This tester is used to evaluate the softness of enamel wire according to the spring elongation method.
One end of the testing coil is to be rolled to the mandrel and the other end attached to a weight which is placed on a supporting platform.
The platform will then go down at a constant speed and when 1 minute has passed after the weight had separated from the supporting platform, the operator is to detach the weight and leave the testing coil for another 1 minute.
The length difference of the coil before and after the test is to be noted as the spring elongation value.
