In order to measure performance characteristics of fibre optic temperature sensors, the IEC has published a new standard IEC 61757-2-1, Fibre Optic Sensors – Part 2-1: Temperature measurement – Temperature sensors based on fibre Bragg gratings. This standard specifies the terminology, characteristic performance parameters and related test methods of fibre optic temperature sensors based on one of the most sensitive sensor techniques available, fibre Bragg gratings, which can simultaneously measure temperature and strain as a single sensor or as a chain of several multiplexed discrete sensors in a single fibre.

This standard provides guidelines to manufacturers of fibre optic temperature sensors for the performance characterization of their products and it also helps the users of these sensors to better understand the performance criteria needed for selection, use and operation of the sensors.
