TEST METHOD

Preferred test parameters, including duration and temperature, are selected via a touch display. The yarn or tape is secured with its free end positioned on the length measurement wheel. Pretension is applied using calibrated weights. Once the sample carrier is manually inserted into the preheated oven, the test initiates automatically. Upon completion of the set testing time, an acoustic signal sounds and the digital display prompts the operator to withdraw the oven and expose the specimen.
