ASTM's temperature measurement standards provide the material and property specifications, as well as guides for the testing, calibration, and use of laboratory, industrial, and clinical instruments used in the determination of thermal variables, particularly temperature. These include thermoelement materials, hydrometers, liquid-in-glass thermometers, thermocouples, resistance thermometers, and thermistor sensors. These instruments quantify thermal parameters by measuring some physical property of a working material that varies with temperature. They are then calibrated either by comparing their results with that of certified thermometers, or by checking them against known fixed points on the temperature scale. These temperature measurement standards are useful to medical and industrial supplies manufacturers, laboratories, and other producers and users of such thermal instruments in helping them fabricate quality equipments towards their safe and accurate utilisation.
