Vicat testing systems increase efficiency in the testing lab

  • For occasional to continuous testing
  • Multiple features for increased working comfort and safety
  • Software for further options

Instron, a manufacturer of material and structural testing systems, is introducing new HDT and Vicat testing systems designed to reduce workload and increase efficiency in the testing lab.

The new Instron HV Series includes three different systems: the entirely manually operated HV3S with two (optionally three) testing stations plus two systems with a larger bath size and a higher level of automation (HV6M and HV6X) for up to six testing stations. All use advanced electronics that automatically zero the position of the LVDT measuring sensors before starting a test, reducing test time and human errors.

For occasional to continuous testing

With its manual lifting station and weights application, the HV3S is very suitable for laboratories that perform low volumes of HDT or Vicat tests. In addition, its compact size makes it an ideal system for busy laboratories with a lot of test equipment. Where HDT or Vicat testing is part of the daily routine, the HV6M features manual weights application on up to six stations with a motorized lifting mechanism designed to significantly reduce operator effort. Where time is crucial, the HV6X system offers motorization of both the lifting station and weights application on all of its up to six testing stations, making it suitable for laboratories with a continuous backlog of specimens. Its interlocked cover shield restricts access during test execution, protecting the user from moving parts. Together with its optionally integrated fume filtering and extraction system, the HV6X is designed for working environments where safety procedures are extremely strict and extraction system automation is required.

Multiple features for increased working comfort and safety

The intuitive weight design eliminates the risk of selection mistakes. The weights are stackable and enable the user to handle them with confidence. A wide range of stress values can be achieved without the need for any additional tools. Users of the HV3S benefit from the smooth lifting mechanism of the stations, combined with ergonomic handle positioning. This allows the stations to be raised and lowered safely and easily. The user-friendly touch screen, which is standard for all three systems, has a simple and clean look and allows for operation without a computer. The intuitive workflow offers seamless interaction with the system for rapid test setup and data export.

All three systems use silicone oil as the heat transfer medium, 9 litres for HV3S, 16 litres for HV6M and HV6X, to cover a temperature range from 20 °C to 300 °C with a resolution of 0.1 °C. A continuous oil monitoring routine not only helps to reduce the risk of running invalid tests but also increases productivity, an alert being issued when the bath level is out of range or oil degradation could adversely affect test results. Rapidly bringing the oil temperature back to its starting level after a test run means the user can start the next test with minimal waiting and reduces water consumption.

Software for further options

The optional Instron Bluehill HV software makes it possible to run tests, edit methods, analyse results or configure the system. It locks the test methods, preventing inadvertent changes, to ensure repeatability and compliance with ISO and ASTM standards over multiple shifts and numerous operators. The software also allows the creation of specific user profiles on the basis of the operator’s level of expertise.
