The systematic difference between the Callendar—Van Dusen function and the ITS-90 polynomial for working platinum resistance thermometers with different values of W(100) is analyzed and it is shown that this difference is not related to the purity of the platinum over a wide range of values of W(100), and depends considerably on the temperature range. A method of calculating the standard relations...
