Your thinking is incorrect. An interpolation algorithm determines the values at points along a curve; it represents an approximate solution for the data. The values provided in the standards are derived from experimental data, and they may correspond to quadratic or cubic curves, or to discrete numbers
The data in the standards come from experiments, and there is no linear relationship; the values between the two temperatures are obtained using interpolation. Is it nonsense to use interpolation to verify the values in the standards? There are values for 300 degrees; one can look them up in standards. For temperatures between 250 degrees and 300 degrees, or between 300 degrees and 350 degrees, interpolation is used.
