Check the sample holder used in this test. If it is three sets of samples, check the three deformations
corresponding to the installed samples, and click "Start test" to start temperature control;
At the end of the test, it will automatically stop heating up, click the "Print" button to take out the test
report.
4.2. Thermal deformation measurement
Plastic bending load thermal deformation temperature test method: Determine the temperature at
which the plastic sample is immersed in a suitable liquid heat transfer medium with a constant
temperature rise, and under the action of a static bending load of a simple beam type, the sample
bending deformation reaches the specified value .
The heat deformation test sample is prepared to cut the sample according to the GB/T1634 or ISO75
test method standard. The conventional test size is (80×10×4) mm and (120×4×10) mm.
Before measuring the thermal deformation temperature, please prepare the sample, perform
pretreatment, measure the specifications and dimensions of the sample, then install the sample, click
the "thermal deformation measurement" button to enter the thermal deformation measurement
interface, as shown in the following figure:
