Physical Properties

Physical property measurements are increasingly required to support component design and process modelling using finite element analysis (FEA) and other computational methods. Inspiratech 2000 Ltd has considerable experience in determining these properties, using state of the art techniques, for metallic and non-metallic materials.

Thermal Properties

In order to model processes or components operating at elevated temperatures, it is often necessary to determine the following properties as functions of temperature:

• Thermal diffusivity
• Heat capacity
• Expansivity

When combined with the room temperature density, these properties can be used to calculate the thermal conductivity as a function of temperature.

Standards

ASTM E228-17	Standard Test Method for Linear Thermal Expansion of Solid Materials With a Vitreous Silica Dilatometer
ASTM E1269-11	Standard Test Method for Determining Specific Heat Capacity by Differential Scanning Calorimetry
ASTM E1461-13	Standard Test Method for Thermal Diffusivity of Solids by the Flash Method
