Siver Plastic Testing Equipment HDT Vicat Tester for ASTM D 648
Heat Deflection Temperature Test
Standard:
Accord with ASTM-D648 JIS-K7191 ISO-2507 GB/T 8802 test standard
requirements.
Scope of application:
Mainly applicable to the determination of plastic test pieces,
thermal deformation HDT... Three-point loading under the bending
stress deformation temperature and plastic Vicat softening
temperature test method ... plastic samples under the specified
conditions, the needle penetration phenomenon temperature.
Principle:
The test machine can choose to use compressor cooling or water
cooling. Compressor cooling with high efficiency can achieve rapid
cooling effect, and save water consumption during water cooling.
All metal materials immersed in high-temperature heat transfer oil
are alloy steels with low deformation coefficient, which minimizes
high-temperature deformation of the material and improves the
accuracy of test results.
Main features:
It has the functions of heating up, cooling down, and stirring
automatic control, automatically displaying the measuring point
temperature. The high-precision LVDT displacement sensor is used to
measure the deformation of the indenter, and with the high-speed
iron's self-developed deformation sensing amplifier, the high
resolution and accurate sensing do not jump.
