Appendixes in the standard provide statistical data for repeatability (within a lab) and reproducibility (between labs). For example, the standard might state that for Aluminum 6061, the Silicon percentage determined by this method should agree within ±0.02% across different instruments.

The standard provides specific precision tables for elements like Si, Fe, Cu, Mn, Mg, Cr, Zn, Ti, and more. astm e125117a pdf

Different spectrometers can yield slightly different results based on calibration. ASTM E1251-17a provides a standardized procedure for sample preparation (usually grinding or polishing), instrument calibration, and data analysis. This ensures that a test performed in a lab in Germany matches the results of a lab in the United States. Appendixes in the standard provide statistical data for
