This table represents the calibration process with predened temperatures. This means if a temperature
standard is available, the resistance value of the test piece must lie within the limits specied above.
For further information on accuracies and limits of use of resistance thermometers,
see data sheet IN 00.17 (download available at www.wika.de).
