The TAPPI Standards regulations require public review of standards that are up for ballot. Send a message to standards@tappi.org if you want to request a copy of the draft in ballot. If you would like to participate in the SSIGs that review and vote on the Standards, please contact TAPPI Standards Department at standards@tappi.org.
