The scientific article presents a synthesis on the analysis of the implementation of metrological traceability requirements specific to measuring equipment used for performing accredited tests in the field of explosives for civil use and pyrotechnic articles. In order to mitigate / minimize the risk related to the measurement uncertainty it is applied the proper traceability path in compliance with the requirements of the RENAR Policy, so that to ensure the availability of objective evidence for supporting metrological traceability, based on the documents of the implemented system. Also, the periodicity of calibration of measuring and testing equipment is between 2 and 6 years, being established according to the following criteria: level of use, regime of use, accuracy and stability requirements imposed in operation, metrological reliability performances of the equipment, quality of the working environment, the manufacturer’s recommendations regarding the stability of the equipment. At the same time, the modification of this period is performed when there are significant changes of one or more parameters taken into account in the previous assessment, and in case of failure of a measuring equipment provided with a calibration certificate, it has to be calibrated again after its’ repair.
