Application
The tester is used to determine the Vicat softening temperature and the heat deflection temperature under load for plastics and thermoplastics.
The attained heat resistance rate of plastic material is a widely required parameter for product characterization, for quality control and for evaluating the conformity to the previewed applications.
“HDT” test means
The test determines the temperature at which a specified deflection occurs when a standard test specimen is subjected to a bending stress, to produce one of the nominal surface stresses according to international standards.
This test is important for both quality control and research into plastics.
“VICAT” test means
The test determines the temperature at which a standard indenter penetrates 1mm into the surface of a test specimen under load.
It is used to establish the difference between many types of thermoplastic materials with regard to their softening properties.
The Vicat softening point temperature is a critical parameter for PVC pipe testing as it indicates the temperature at
which the PVC material begins to soften and lose its structural integrity. This is important for PVC pipes as they are
commonly used in applications where they are exposed to high temperatures, such as in hot water systems or
outdoor environments.
The Vicat testing machine is needed for testing PVC pipes because it allows for accurate and precise measurement
of the softening point temperature. This is done by heating a sample of the PVC material at a controlled rate until
it reaches a specific temperature, at which point a needle is used to measure the penetration of the material. This
provides a quantitative measurement of the softening point temperature, which is crucial for ensuring the quality
and performance of PVC pipes in various applications.
Overall, the Vicat softening point temperature and the Vicat testing machine are essential tools for evaluating the
thermal stability and performance of PVC pipes, helping to ensure their durability and reliability in use.
