Possible routes for traceability for callibration

Confidence in the reliability and accuracy of a measuring system is in part derived from the ability to demonstrate or calibrate its performance against norms or reference materials, which are founded on reliable, calibrated sources. The route through which the calibration of the reference material can be traced is not straightforward for strain, which is a relative change in length, and hence is not measured but derived from some other measurement e.g. birefringence and optical path length. Possible routes for trace ability for calibration of systems have been proposed to cover applications in all areas of engineering where strain levels are of interest. They are being promulgated on the project website.
