QT-300A HDT&Vicat Tester

Product picture:(for reference only)

The machine specification:

HDT VICAT Heat Deflection Testers is designed and manufactured according to the latest international and national standards for non-metallic material. HDT VICAT Heat Deflection Testers is used to measure HDT and Vicat temperature of plastic, hard rubber, nylon, electrical insulation material, long fiber reinforced composite material and high strength thermosetting laminate material.

Instrument features:

The operation is easy and the control is precision. And the machine is a very intelligent tester. HDT VICAT Heat Deflection Testers is commonly used in colleges, scientific research units and products quality supervision and inspection units. It adopts Chinese LED display. The testing results is clear and intuitive. HDT VICAT Heat Deflection Testers uses single microcomputer control, PID phase adjustment output with upper limit temperature setting when the testing temperature reaches the upper limit.

Standards

Parameters

VST definition：The specimen is placed in liquid or heating cabinet. It tests that about the temperature of standard needle when pressed 1mm into a sample from pipes or fittings under (50+1)N force withisokinetic heating.

HDT definition：The test specimen is loaded in three-point bending in the edgewise direction or horizontally，producing bending strength stated in GB/T1634 relevant part. Under the condition of isokinetic constant temperature, it measures the temperature when it reaches the standard deflection corresponding to specified bending strain increased.
