1.1 This standard prescribes the method for determination of the heat distortion temperature of rigid cellular thermal insulation materials using a cantilever test specimen.
1.1.1 The test is useful for the initial screening of rigid cellular thermal insulation materials.
Note — The heat distortion temperature values obtained are dependent on the specified method of test and the loading conditions used and no correlation with the maximum temperature of use of a material in service is implied.
