Standard Guide for Using Statistical Process Control Principles for Routine Dosimetry in Radiation Processing

Importancia y uso:

4.1 Control charts are the primary process monitoring tool in SPC for radiation processing. The general objectives of implementing a SPC program with control charts are to:

4.1.1 Increase knowledge of the process,

4.1.2 Control the process to provide a targeted or required process output,

4.1.3 Reduce variation of the process output or in other ways improve the performance of a process, and

4.1.4 Identify single process run results that are outside of established control limits but may be within the USL and LSL limits.

4.2 These objectives when achieved:

4.2.1 Reduce costs through reduction of losses due to scrap, rework, and investigation time,

4.2.2 Improve consistency of the process output,

4.2.3 Facilitate preventive process adjustments, and

4.2.4 Provide evidence of accurate process targeting and process performance; state of statistical control.
