Modern applications drive the materials technologist to develop materials capable of ever increasing performance at extended temperature ranges. This in turn pushes the test and measurement engineer to satisfy the demanding test requirements of the technologist in order to properly evaluate and develop these new materials.
Anter slug calorimeter for testing thermal conductivity of fire resistant materials.
Anter Laboratories, based in Pittsburgh, USA, have added five new test instruments designed, developed and manufactured by their affiliates Anter Corporation, to their extensive testing facilities and are now able to carry out thermal measurements for the following:-
- Thermal resistance of thermal interface materials from ambient to 150°C using the newly designed Quick-line 50 Thermal Impedance Meter, this being of particular interest to the electronics industry.
- Thermal conductivity of Fire Resistant materials, using a recently designed slug calorimeter, from 20°C to 1000°C in accordance with the new ASTM standard E-2589.
- Thermal conductivity of low to moderate conductivity non-carbonaceous materials using the hot wire method (ISO 8894) up to 1400°C.
- Linear thermal expansion coefficient and other changes in linear dimensions using a high precision vertical dilatometer from 20 to 2800°C in accordance with ASTM E-228.
- Thermal conductivity of low conductivity insulating materials using a new design of Guarded Hot plate over a temperature range of -175°C up to 500°C,
in accordance with ASTM C-177.
Typical turn round time for test results is 2-3 weeks making outsourcing of such specific measurements a sensible option when only a few samples need to be tested, or a new material characterised.
Anter is represented in the UK by Nortest.
