DOWNLOAD EBOOKThe monograph describes the methods and equipment employed at the National Bureau of Standards for calibrating standard platinum resistance thermometers (SPRT) on the International Practical Temperature Scale (IPTS-68).The official text of the scale is clarified and characteristics of the scale are described.Several designs of SPRT's are shown and discussed in the light of the requirements and recommendations on the text of the IPTS-68.Possible sources of error such as those due to the internal and external self-heating effects and the immersion characteristics of SPRT's are described in detail.Precautions and limitations for the mechanical and thermal treatment and for the shipment of SPRT's are indicated, and a guide is given for those desiring the thermometer calibration services of NBS.(Modified author abstract).

The Standard Platinum Resistance Thermometer (SPRT) Calibration Laboratory of the NIST Thermometry Group realizes the ITS-90 from the argon triple point (Ar TP, 189.3442 °C) to the silver freezing point (Ag FP, 961.78 °C) for the calibration of SPRTs. This special publication describes the calibration services, methods, measurement assurance, and uncertainties for the NIST ITS-90 calibration SPRTs.

DOWNLOAD EBOOKThe Standard Platinum Resistance Thermometer (SPRT) is defined by the International Temperature Scale of 1990 (ITS-90) as the interpolating instrument for temperatures between 13.8033 K and 1234.93 K. This SRM concerns the calibration characteristics of a group of 20 capsule-type SPRTs within the range of temperatures between 13.8033 K and 429.7485 K. The platinum wire used for the construction of the resistor elements of this SRM was derived from platinum bar stock with a chemical purity of 99.999 % by weight. Each of the 20 units has been evaluated, certified, and calibrated according to the definitions of the ITS-90. The resistance characteristics of all 20 units have been measured at 11 fixed point temperatures from 4.22 K to 429.7485 K as well as at least 7 other intermediate points. The procedures used in performing the calibrations and the supplemental measurements are documented in this publication. The resulting analysis pertaining to each individual unit, as well as the SRM sample population as a whole, is presented in detail.

DOWNLOAD EBOOKExcerpt from Standard Reference Material 1750: Standard Platinum Resistance Thermometers, 13. 8033 K to 429. 7485 K The calibration data are used to produce a set of numerical coefficients for two deviation equations for the its - 90 sub-ranges of K to K and K to K. When these two deviation equations are combined with the appropriate its 90 reference functions, the sprt can be used to interpolate all temperatures within the range of calibration.
