Product Description
Ray-Ran’s Advanced 4 Station HDT/Vicat Apparatus has been designed to allow microprocessor control of the heat deflection & softening point testing for all polymer and plastic materials.

HDT – Heat deflection / distortion test, where a standard sized test specimen is subjected to a bending stress, whilst the temperature is raised at a uniform rate. The temperature at which the specified deflection occurs is measured and recorded. Testing is carried out in accordance with the ISO 75 (parts 1, 2 and 3) and ASTM D648 Test Standards.

Vicat (VST) – Softening point test, where a specified needle (indentor) penetrates a specifed distance into a sample with a specified load, whilst the temperature is raised at a uniform rate. The temperature at which the sample was penetrated is recorded at the Vicat Softening Temperature (VST). Testing is carried out in accordance with the ISO 306 and ASTM D1525 Test Standards.

The 4 Station Advanced HDT/Vicat apparatus allows testing of 4 samples at the same time, with an automatic cooling system, LCD display to provide automatic prompts for test procedures, calibration and results, HDT binary loads automatically calculated by microprocessor, over temperature protection, flatwise / edgewise sample testing, integrated calibration system. Tabular results presentation.

Standard features include
Digital temperature control, Temperature range to 300oC (temperature tests in excess of 250oC require the nitrogen blanket option), HDT Heads (1 per station), Vicat Nibs (1 per station), User selectable Fibre Stress 0.45, 1.8 or 8.00 MPa or a non standard fibre stress can be entered, User selectable Vicat penetration of 0.1mm or 1.00mm or a non standard penetration can be added, Temperature resolution +/- 0.1oC, User selectable temperature ramp rates of 50oC or 120oC per hour (non standard ramp rates can also be entered), Adjustable HDT span supports of 64mm or 100mm, Deflection / Penetration resolution +/- 0.01mm, Bath capacity 18 litres, RS 232 connection, RS232 Cable, Windows File Capture Software, Fully traceable certificate of calibration, Product user manual, CE mark of conformity, 1 year return to base warranty,

Test Description
HDT – Determines the temperature at which a test sample subjected to a predetermined bending stress, deflects to a set distance.

Vicat determines the temperature at which an indenter penetrates into the test sample when a given load is applied
