ASTM E2281 – Standard Practice for Process Capability and Performance Measurement
This practice provides guidance for determining process capability and performance under several common scenarios of use including:
- normal distribution based capability and performance indices such as Cp, Cpk, Pp, and Ppk;
- process capability using attribute data for non-conforming units and non-conformities per unit type variables
- additional methods in working with process capability or performance.
