A transition period to version 3.0 will be applied to allow a smooth transition to the new rules:

  • The publication of the new version of the GPI does not affect the validity of already-published EPDs, which will remain published with the same validity date as before. Surveillance of EPDs during their validity is based on the same version of the PCR and GPI that was used for the verification of the current valid EPD.
  • If a valid PCR based on version 3.x of the GPI does not exist, EPDs may be published and updated based on valid PCRs that are based on version 2.x of the GPI during the transition period.
  • Version 3.0 of the GPI will be implemented step-by-step into existing PCRs when they are due for update, or during their validity.
  • PCRs that are currently under development should be aligned with the new programme instructions. Exceptions are allowed for cases where the development is already far progressed. The Secretariat and Technical Committee are currently updating the PCR Basic Modules to act as a template for new and updated PCRs.

The transition period will last for at least 18 months, and the end of the transition period will be announced six months before it ends.

Work has also started to update the website, templates, etc., which will be introduced gradually.
