Application Summary AI generated

This standard specifies the statistical methods for constructing and interpreting control charts that use the arithmetic average of a sample alongside predefined warning limits. It is applied in industrial production and quality management processes to monitor process stability, detect shifts in the mean, and trigger corrective actions when sample averages fall outside the warning limits. The standard is particularly relevant for manufacturing sectors where continuous or batch production requires real-time statistical process control to maintain product quality.
