QT-300A HDT Vicat Tester

Introduction:Plastics HDT Heat Deflection Vicat Softening Point Teste QT-300B

Plastics HDT Heat Deflection Vicat Softening Point Tester specification:

Plastics HDT Heat Deflection Vicat Softening Point Tester is designed and manufactured according to the latest international and national standards for non-metallic material. It 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. It 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. It uses single microcomputer control, PID phase adjustment output with upper limit temperature setting when the testing temperature reaches the upper limit.

Standards：

Standards number	name
GB/T 1633	Testing of Vicat(VST)
GB/T 1634.1	Temperature testing of plastic and load deformation（genenral testing method）
GB/T 1634.2	Temperature testing of plastic and load deformation（plastic, hard rubber and long fiber reinforced composite material）
GB/T 1634.3	Temperature testing of plastic and load deformation（high strength thermosetting laminate material）
GB/T 8802	T BV esting of softening temperature of vicat for thermoplastic pipes and fittings
ISO 2507、ISO 75、ISO 306、ASTM D1525,ASTM D648 and so on.

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 with isokinetic 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.
