This paper describes the development of experimental methods for the metrological characterization and traceability of an in house produced strain column measurement standard, for use in hardened concrete compression machine testing. The performed characterization included the determination of dimensional (diameter, height) and geometrical quantities (flatness, shape, parallelism, perpendicularity, circularity and cylindricity) using a three-dimensional coordinate measuring machine, and the evaluation of the strain measurement accuracy and uniformity. Traceability to the International System of Units (SI) was achieved by calibration using a laser interferometer. The obtained estimates and measurement uncertainties supported its conformity assessment, considering the applicable EN 12390-4 normative tolerances and adopted decision rule (hypothesis test, without guard bands, assuming a type I error of 1% and a Gaussian probability density function). This work allowed concluding that the produced strain column complies with all the normative technical requirements and can be used in the metrological testing of hardened concrete compression machines.
