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.

SSIG Members Needed

The Standard-Specific Interest Groups (SSIGs) for the following standards are in need of additional members

All Standard-Specific Interest Groups (SSIG) require a minimum of 10 members in order to ballot and vote on a draft of a method. The following test methods do not have the required minimum number of member to initiate a ballot:

T 245 Silicates and silica in pulp (wet ash method). Requires 3 more SSIG members.

T 255 Water-soluble sulfates in pulp and paper. Needs 2 more members.

T 406 Reducible sulfur in paper and paperboard. Needs 2 more members.

T 421 Qualitative (including optical microscopic) analysis of mineral filler and mineral coating of paper. Requires 3 more

members.

T 438 Zinc and cadmium in paper. Requires 1 more member.

T 602 Analysis of sulfuric acid. Requires 1 more member.

T 656 Measuring, sampling, and analyzing white waters. Needs 4 more members.

T NEW (WI 3033) Conformational isomerism of cellulose under incremental stress or strain. Needs 6 members.

T NEW (WI 3034) Identification of non-native cellulose in cellulose-based composites. Needs 7 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
