HDT VICAT Testing Machine

Model: HVT301 / HVT303 / HVT305

Table type HDT VICAT Testing Machine  is mainly used to determine temperature of deflection under load and Vicat softening temperature of thermoplastic plastics, pipes and fittings.  

As table type, the frame is low in height and small in the test frame, can put on the desk, save lab space and convenient for user operation.  

General introduction

Table type HDT VICAT Testing Machine  is mainly used to determine temperature of deflection under load and Vicat softening temperature of thermoplastic plastics, pipes and fittings.  

As table type, the frame is low in height and small in the test frame, can put on the desk, save lab space and convenient for user operation.  

HDT VICAT Testing Machine

Main Features

  • Key feature
  • Standard
  • Test Procedure

1, Can execute both HDT and Vicat tests on the one machine, only change loading nose for HDT test, and needle for VICAT test.

2, Conforms to ISO 75, ISO 306, ISO 2507 and ASTM D648, ASTM D1525, ASTM D5944, ASTM D5945. GB/T 8802, GB/T 1633, GB/T 1634

3, Three working stations, with all necessary press nose, needle and weights. 

4, Use the Digital micrometer to replace the old dial indicator and displacement sensor, more accuracy; 

5, Table type;

6, Three kinds display and operation mode for selection; digital economical, 5.7” touching screen and computer controlled. 

7, Manual lifting sample racket type; 

8, Micro-Printer function to print test report; 

9, With CE certificate. 

ISO 75 Plastics -- Determination of temperature of deflection under load

ISO 306 Plastics -- Thermoplastic materials -- Determination of Vicat softening temperature (VST)

ISO 2507 Thermoplastics pipes and fittings -- Vicat softening temperature

ASTM D648 Standard Test Method for Deflection Temperature of Plastics Under Flexural Load in the Edgewise Position

ASTM D1525 Standard Test Method for Vicat Softening Temperature of Plastics.

HDT Heat deflection temperature test:

The bars are placed under the deflection measuring device. A load of 0.45 MPa or 1.80 MPa is placed on each specimen. The specimens are then lowered into a silicone oil bath where the temperature is raised at 2° C per minute until they deflect 0.25 mm for ASTM, 0.32 mm for ISO flatwise, and 0.34 mm for ISO edgewise.


VST VICAT softening point test:

A test specimen is placed in the testing apparatus so that the penetrating needle rests on its surface at least 1 mm from the edge. A load of 10N or 50N is applied to the specimen. The specimen is then lowered into an oil bath at 23 degrees C. The bath is raised at a rate of 50° or 120° C per hour until the needle penetrates 1 mm.
