A Good Practice Guide on measurement uncertainty for the calibration of Fibre Bragg Grating thermometers

Year: 2026

Type: article

Abstract: This guidance document is an output of the 22IEM07 INFOTherm project (“IntegratedEuropean research, calibration and testing infrastructure for fibre-optic thermometry”).It serves as a foundational advisory document for calibration laboratories establishinguncertainty budgets for fibre-optic thermometers.Specifically, this guide addresses measurement systems consisting of a Fibre BraggGrating (FBG) sensor and an optical interrogation unit calibrated together as a singlesystem. The covered calibration range spans from 0 °C to 700 °C, at atmosphericpressure and in accordance with the International Temperature Scale of 1990 (ITS-90).Although the metrological principles outlined here may apply to other fibre-opticmeasurement configurations, those systems may introduce additional unique influencequantities and experimental considerations that are outside the scope of thisdocument.
