ASTM D1200

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Determinations should be made at a temperature above the dew point of the atmosphere surrounding the apparatus. 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 thermometer 17C and 17F, may be used.
