Managing Measurement Uncertainty

From CGI Inspection

In metrology, measurement uncertainty and the resulting potential for error are always present. Regardless of the technology employed, there can be an accumulation of tolerance errors in each element of the measurement process that puts the reliability of the inspected dimension in doubt. According to NIST (National Institute of Standards and Technology), a quantitative statement of the measurement uncertainty should accompany all inspection data. Therefore, it is critical to manage uncertainty and to understand that the sources of error go beyond the measurement tool.
