... that to participate in the balloting process for TAPPI Standards you must sign up for the Standard-Specific Interest Groups (SSIGs)? Drafts are available for anyone to review, but to vote and comment you must be a member of the SSIG. Each Standard has its own SSIG – so you have to sign up for each Standard that you have an interest in. Contact the Standards Department at standards@tappi.org if you would like to join any SSIG. To see the complete list of TAPPI Standards, check our Numeric Index.
