HDT & Vicat strain temperature tester of materials QT-300B

Product features:

  • The machine is designed and manufactured according to the latest international standards for non-metallic materials.
  • The HDT & Vicat strain temperature tester of materials QT-300B is used to measure the HDT and Vicat temperatures of plastics, hard rubber, nylon, insulating materials, long fiber reinforced composites and thermosetting laminates. high amtitude.

Measurement methods:

  • VST method: The test specimen is placed in a liquid or heating cabinet. It tests the temperature of a standard needle when pressed 1mm into the sample from a tube or fitting under a force of (50 + 1) N with isokinetic heating.
  • HDT method: The test piece is subjected to a three-point bending either vertically or horizontally giving the flexural strength specified in the relevant section GB/T1634. Under the isokinetic constant temperature condition, it measures the temperature when it reaches the standard deflection corresponding to the increased bending strain.
