Validity of PCRs

A PCR is valid for a pre-determined period of time to ensure that it is updated at regular intervals. Any interested party may comment on a published PCR document via the PCR Forum or send comments via e-mail to the PCR Moderator and the Secretariat. Such comments may lead to an update during the period of validity, or should be recorded and used as input when the PCR document is subject for a later update.

An expired PCR shall not be used to develop and register new EPDs, and shall not be used to update a published EPD to give the EPD a prolonged period of validity. To be possible to use for these purposes, the expired PCR shall first be updated or have its period of validity prolonged.

Updated PCRs shall either have an updated version number or be assigned a new registration number
