to allow placement of temperature sensors in the specimen as in Test Method E1225.
This standard imposes an idealized heat flow pattern and specifies an average specimen test temperature. The thermal impedances thus measured cannot be directly applied to most practical applications where these required uniform, parallel heat conduction conditions do not exist.
This standard is useful for measuring the thermal impedance of the following material types.
Type IViscous liquids that exhibit unlimite
