- Abstract:
- This article contains a description of the technical, process-related and organizational procedures which accredited calibration laboratories use as a model for defining internal processes and regulations. By implementing these procedures, it is ensured that the devices to be calibrated are all treated equally in the various calibration laboratories and that the continuity and comparability of the work of the calibration laboratories are improved. The calibration certificates issued by the accredited laboratories prove the traceability to national standard as required by Standard HRN EN ISO/IEC 17025:2017 [1]. This procedure defines minimum requirements to be met by work area and equipment required to calibrate a measuring instrument used for measuring braking force on the periphery of wheels of road vehicles (hereinafter: roller brake tester), as well as the calibration procedure and the estimation of the measurement uncertainty. This article describes static method for calibration of roller brake testers. Some of the measurement uncertainty contributions stated in this document as most relevant contributions that have to be considered during uncertainty calculation, may still be exempted from measurement uncertainty calculation. In those cases calibration laboratory must prove the exemption by reasonable means such as calculations, measuring results, statistics, etc.
