DX8425 Plastic Load Deformation Testing Machine

DX8425 Plastic Load Deformation Testing Machine

Scope of application:

It is mainly suitable for rigid plastics connected by rivets, bolts or similar connections, to determine their ability to withstand compression over time without yielding or loosening; Applies to non-rigid plastics to determine their ability to deform and return to their original dimensions over time.

Standards:

Meets the requirements of the ASTM D621 Test Standard for Testing Deformation of Plastic Loads.

Technical Parameters:

Loading form: A constant load of 113kg, 227kg, 454kg±1% is applied in two parallel pressure plates of the testing machine. The pressures of these two plates can be adjusted so that they are in full contact with the specimen before the load is applied;

Bearing: In order to make the load act evenly on the surface of the sample, one of the machine supports can be adjusted, and the load can pass through the center line of the sample;

Deformation meter: the measurement accuracy < 0.001mm

Micrometer: 0.001mm

Test ambient temperature requirements: 23°C±5°C

Test environment humidity requirements: 50%±5%;

Power supply: 220v 50Hz

Working principle:

Put the sample in the middle of the parallel plate with a unit of measurement, carry out the required force conditions through the conventional loading system, and read the thickness change of the test sample at the specified temperature and conditions.
