Evaluate measurement system variation using the AIAG MSA methodology. Enter measurements for multiple parts, operators, and trials. Calculate repeatability, reproducibility, %GRR, and ndc.
Results
%GRR Criteria
< 10% — Excellent. Measurement system acceptable.
10–30% — Conditionally acceptable. May be acceptable depending on application and cost.
> 30% — Unacceptable. Measurement system needs improvement.
These %GRR acceptance thresholds and the ndc ≥ 5 criterion come from the AIAG MSA (Measurement Systems Analysis) manual. ISO 5725 defines the underlying concepts of repeatability and reproducibility for measurement methods, but it does not set these acceptance bands.
Number of Distinct Categories (ndc)
ndc ≥ 5 indicates the measurement system can adequately distinguish between parts.
High-precision vibration measurement instruments for reliable MSA-compliant data collection.
