The main advantages to the laser flash method is its speed to complete a non-destructive test which typically takes a few seconds to perform. Also, the method is capable of measuring thermal conductivity over a wide temperature range, from -120°C to 2,800°C and with measurement error of less than 3%. Lastly, this method has the capability to measure very small sample sizes, such as samples that have 5mm to 12mm diameters. One of the main disadvantages to this method is the fact that it makes several assumptions about the sample such as homogeneity and material density, as well as specific heat capacity. Many of Chomerics products are not homogenous and the density and specific heat capacity are slightly variable due to the manufacturing processes. With these slight inaccuracies, the errors may “stack up”, yielding a large error in thermal diffusivity. The other disadvantage is if the sample holder heating up is not properly accounted for, this could lead to significant error in the measurement. Due to the error associated with Chomerics’ products, the Laser Flash Method does not accurately represent the products in the end-use.
