Reference Materials

Sets and Individual Materials

Please note when using reference samples with special dimensions that it is essential to maintain a diameter-to-thickness ratio of >5. Lower ratios might decrease accuracy. To ensure reliable test results, the thermal diffusivity should fall within ±3% in terms of accuracy.

The following tables show sets and individual reference materials for the determination of thermal diffusivity and specific heat (cp).

Recommended reference materials are listed separately from those which differ in dimensions. These reference materials should be used to evaluate the diameter-to-thickness prior to the LFA measurement.
Please consider to adjust the reference materials to the sample holder you selected.
