Standard Guide for the Preparation and Evaluation of Liquid Baths Used for Temperature Calibration by Comparison

Importancia y uso:

5.1 The design of a controlled temperature bath will determine what thermometers can be calibrated and to what extent an isothermal condition is achieved. The lack of thermal stability and uniformity of the bath are sources of error that contribute to the overall calibration uncertainty.

5.2 This guide describes a procedure for determining the effective working space for a controlled temperature fluid bath.

5.3 This guide describes a procedure for determining the thermal stability within a controlled temperature fluid bath. Overall thermal stability is composed of the bath performance as specified by the manufacturer of the bath equipment and as a component of calibration uncertainty.

5.4 This guide describes a procedure for determining the temperature uniformity of the working space of the controlled temperature fluid bath.
