ASTM D 2. Last previous edition approved in as D — 94 In addition, temperature measuring devices such as non-mercury liquid-in-glass thermometers, thermocouples, or platinum resistance thermometers that provide equivalent or better accuracy and precision, that cover the temperature range for r1200 17C and 17F, may be used.

Temperature of Testing 8. NOTE 2— It is impossible to predict the effect of temperature change on each material with which the apparatus e1200 be used. Determinations should be made at a temperature above the dew point of the atmosphere surrounding the apparatus.

Allow to stand undisturbed for 10 min while adjusting further to the desired temperature.
