How to Apply

To successfully apply for an equivalency recommendation:

  • Notify the Pathogen Equivalency Committee (PEC) of your intent;
  • Develop a sample;
  • Create an analysis plan to gather data in support of your process's equivalency;
  • Carry out that sampling plan; and
  • Complete and submit an official pathogen reduction equivalency application package.

The PEC will then evaluate the package and make its recommendation through the appropriate channels. Figure 1 demonstrates the typical equivalency recommendation process.

  • Initiation Phase

  • Application Phase
