Vicat Softening Point & Heat Deflection Temperature apparatus, as per ASTM D1525, ASTM D648, ISO 306 and ISO 75.
The VSP / HDT Apparatus — Vicat Softening Point and Heat Deflection Temperature apparatus — is used to determine the vicat softening temperature and heat deflection (heat distortion) temperature of polymers, compounds and engineering plastics, as per ASTM D1525, ASTM D648, ISO 306 and ISO 75. These temperatures indicate the point at which a plastic begins to soften or deflect under a defined load, which is critical for selecting materials for parts that operate at elevated temperatures.
A specimen is immersed in a heated bath under a standard load while a sensor (or dial gauge) tracks penetration or deflection as the temperature rises at a controlled rate. International Equipments offers a Computerised model with 2 to 6 stations, which displays VSP and HDT results on a microcontroller and produces Penetration/Deflection vs Temperature graphs and reports through a PC, as well as an Analogue 2-station model with a dial gauge. Both cover ambient to 300°C with 120°C/hour and 50°C/hour heating rates and a weight set from 5 g to 2000 g.
