Special note: Documents appearing in the TAPPI online version of the Standards and TIPs are updated once a month (usually around the 15th). So it is possible that there is a delay between the publication announcement and the posting online. If you are a subscriber to the online access to Standards and TIPs and you are in a hurry for new documents that have not yet been posted, you can send a request to standards@tappi.org.

SSIGs that need 1 member:
T 255 Water-soluble sulfates in pulp and paper.
T 438 Zinc and cadmium in paper.
T 602 Analysis of sulfuric acid.
SSIGs that need 2 members:
T 406 Reducible sulfur in paper and paperboard.
SSIGs that need 3 members:
T 245 Silicates and silica in pulp (wet ash method).
T 421 Qualitative (including optical microscopic) analysis of mineral filler and mineral coating of paper.
SSIGs that need 4 or more members:
T 656 Measuring, sampling, and analyzing white waters. Needs 4 members.
If no progress is made on balancing these SSIGs, then the respective methods may be considered for withdrawal at the next Q&SMC meeting. If you have an interest in becoming a member of either of these SSIGs please contact standards@tappi.org
