US Patent 7329043 Thermal properties testing apparatus and methods

An apparatus for testing properties of a product comprising a thermal barrier layer comprises an ignition source, a test stand that extends a sample of the product over the ignition source, and a means for measuring thermal transfer across the sample. The apparatus may further comprise a means for measuring thermal transfer across each layer of the sample. A method for testing properties of a product comprising a thermal barrier layer comprises supporting a sample of the product over an ignition source, heating the sample via the ignition source, and determining a thermal differential across the sample. The method may further comprise determining a thermal differential across each layer of the sample.
