TL;DR

This paper introduces a power-law interpolation method for AC-DC differences in thermal transfer standards, enabling smooth and consistent estimation across all calibration ranges based on the assumption of smooth variation.

Contribution

It proposes a novel power-law interpolation approach for AC-DC differences, applicable universally across standard ranges without range-specific adjustments.

Findings

Applicable to all working ranges of thermal transfer standards

Based on the assumption of smooth variation of differences

Abstract

In this work we present a general method, commonly applied to the numerical analysis of stochastic models, to interpolate AC-DC differences (usually denoted by the greek letter $\delta$) between calibration points in thermal transfer standards. This method assigns a power-law behaviour to AC-DC differences, solely under the assumption that $\delta$ must be some smooth-varying function of voltage and frequency. We argue it may be straightfowardly applied to all working ranges of the standards, with no distinction.
