- Abstract:
- The measurement result by a standard may become unreliable without regular calibration, which may disrupt the chain of metrological traceability. Different chains of metrological traceability led to different measurement uncertainties. The readings of any standard change between calibrations due to its drift. The standard drift affects metrological traceability at all levels of its hierarchy. Taking into account the drift of the standard in practice may include the following elements: determining the appropriate component of the total measurement uncertainty; establishing the frequency of calibration of the standard; using correction during calibration; documenting metrological traceability. A special procedure and software are proposed to simplify the consideration of the influence of time drift of standards on the provision of metrological traceability by calibration laboratories for calibration of standards and measuring instruments.
