The system for review and development of TAPPI Standards requires an announcement of review dates so that any interested TAPPI parties may access drafts, submit comments, and/or joinStandard-Specific Interest Group (SSIG) to cast an official vote.

Listed below are the Standards that will be up for review in 2022. The date indicated is the target date on which the draft will be distributed to the SSIG for that particular Standard. Any interested individuals who wish to be part of the voting for any Standard should send a message to or sign up on the SSIG request page for voting membership on the corresponding SSIG prior to the target ballot date, if possible (SSIGs are listed under respective subject categories). Anyone who joins the SSIG before the target balloting date will receive a notice of the ballot.
