  • 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.
