Test Method for Thermal Conductivity, Thermal Diffusivity and Volumetric Heat Capacity of Engine Coolants and Related Fluids by Transient Hot Wire Liquid Thermal Conductivity Method

Significance and Use 5.1 This test method covers the measurement of thermal properties for engine coolants (aqueous or non-aqueous) and related fluids. 5.2 With each single measurement, the thermal conductivity (λ) and thermal diffusivity (α) are measure
