Vicat softening temperature and heat deflection tester for thermoplastics under constant load and constant heating rate.
Overview
The Vicat Softening Point Tester (VST / HDT) is used to determine the Vicat softening temperature (VST) of thermoplastics and other non-metallic materials under constant load and constant heating rate, and can also be used for heat distortion temperature tests. The instrument consists of a temperature-controlled heating oil bath, two parallel test frames, indenters/needles, a deformation measuring device, a digital temperature control unit and a cabinet. It features stable heating rate, high temperature and deformation resolution, accurate load and dual-station parallel testing. It is suitable for plastics, rubber and chemical material manufacturers, quality inspection institutions and scientific research laboratories.

FAQ
Q1: What standards does the Vicat Softening Point Tester (VST / HDT) comply with?
A1: The Vicat Softening Point Tester (VST / HDT) is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the Vicat Softening Point Tester (VST / HDT) be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
