This standard describes a procedure for determining the change of resistance with temperature of alloy wire (including material of non-circular section) used for resistance standards and precision resistors for electrical apparatus. The maximum range of temperature covered is —65°G to + 200°C. This standard provides for the presentation of the results in the form of a graph, as a change of resistance between specified temperatures, or as the coefficients in a resistance/temperature equation.
