This standard covers the test method to determine the thermal conductivity of non-metallic liquids. It can also be applied to liquids that are: (1) chemically compatible with borosilicate glass and platinum; (2) moderately transparent or absorbing infrared radiation; and (3) having a vapor pressure less than 200 torr at the test temperature. Note 1. Materials with vapor pressure up to 345 Kpa (50 Psia) absolute can be tested, as long as the necessary measures are taken to avoid volatilization of the sample, subjecting the thermal conductivity cell to pressure. Normal pressure vessel safety precautions should be taken. 2 The materials, operations and equipment used in the application of the standard may present risks. This standard is not intended to point out all the industrial safety problems related to its application. The user of the standard has the responsibility of establishing, before using it, the appropriate industrial safety and occupational health conditions and, likewise, applying the current legislation in this regard. 3 Normalized values are given in SI units. Values in parentheses are for informational purposes only.
