Force is applied to the top of the stack to ensure excellent thermal contact between the test and reference samples. Diagram illustrating the sample set up used for thermal conductivity measurement with the Guarded Comparative Longitudinal Heat Flow technique.
Physical Review, 5p. If the document is revised or amended, you will be notified by email. All measurements are taken after the sample has reached equilibrium to fulfill the requirements of the steady state set up. Need more than one copy? Insulation is placed on either side of the sample set up to ensure that no heat is lost wstm. Principles of Heat Transfer. This standard was reviewed and revised in This standard is also available to be included in Standards Subscriptions.

The sample to be tested is pressed between two reference samples of equal size and shape and a known thermal conductivity. Two major findings of that particular study outlined how to classify homogenous materials for use in the technique, and proper sample sizes needed for heterogeneous testing.
The Guarded Comparative Longitudinal Heat Flow technique has been in use since the s, however extensive work went into further aztm in the s and s.
