Environmental factors like temperature shifts and optical degradation can cause an instrument's readings to drift over time. ASTM E1251 mandates regular standardization using setting-up samples (SUS) to correct the calibration curves mathematically without re-running an entire suite of CRMs. 4. Precision and Bias Control
The aluminum industry relies on this standard for several reasons:
