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. 

TAPPI Standards guidelines require that all TAPPI members receive notification of any proposed new Standard or TIPs. This message is being sent to you because you are a TAPPI member; have purchased TIPs or Standards products from TAPPI; or because you have previously expressed interest in this topic.
