4.1 This practice will provide the following: (1.1 This practice covers (1) a statistical procedure for analyzing the test data generated in the statistical process control of a carbon black manufacturing process; (2) a format for reporting process capability determined from the analysis of control chart data of an individual production run, and (3) a format for reporting process performance determined from the analysis of control chart data of an individual production run. 1.2 This practice specifically applies to the analysis of pelleted carbon black samples taken during the manufacturing process prior to storage. This practice does not apply to shipment samples taken from hopper cars or other containers or packages. 1.3 This practice is specifically designed to be used for those test methods given in Classification D1765 which specify target values. However, these techniques are applicable to other test methods on carbon black. 1.4 This practice describes the calculation for two methods of determining capability factors from an analysis of process control data. 1.4.1 Process capability (Cp) is a measurement of variation
calculated from the process control chart data with the use of an
estimated standard deviation (^σ) from the mean
value of the moving range (R) chart. The calculation of the process
capability (1.4.2 Process performance (Pp) is a measurement of variation
calculated from the process control chart data using sample
standard deviation(s). The calculation of the process performance
