Applicable scope:
Mainly suitable for hard plastics connected by rivets, bolts or similar connections, to determine their ability to withstand compression over time without yielding or loosening; Suitable for non rigid plastics, determining their ability to recover to their original size over time after deformation.
Compliant with standards:
Complies with the testing standard requirements of ASTM D621 Plastic Load Deformation Testing Method.
Technical parameters:
Loading form: Apply a constant load of 113kg, 227kg, and 454kg ± 1% to the two parallel pressure plates of the testing machine. These two plate pressures can be adjusted so that they can fully contact the specimen before applying the load;
Support: In order to evenly distribute the load on the specimen surface, one of the machine supports can be adjusted and allow the load to pass through the centerline of the specimen;
Deformer: measurement accuracy<0.001mm
Micrometer: 0.001mm
Test environment temperature requirement: 23 ℃± 5 ℃
Test environment humidity requirement: 50% ± 5%;
Power supply: 220V 50Hz
Working principle: Place the sample in the middle of a parallel plate with a measuring unit, apply the required force conditions through a conventional loading system, and read the thickness change of the test sample at the specified temperature and conditions.
