New or Revised Standards, TIPs, and Useful Methods

TIP 0404-35 "Application of dryer bars" (Revised)

TIP 0404-31 "Recommended dryer differential pressures" (Revised)

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.

TAPPI Standards in Ballot

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 draft in ballot.

Listed below are TAPPI Standards that have recently gone out for ballot to the corresponding Standard-Specific Interest Group (SSIG). The date in parentheses is the closing date for voting.

T 656 cm-07 "Measuring, sampling, and analyzing white waters" (July 8, 2016)

T 418 cm-07 "Organic nitrogen in paper and paperboard" (July 9, 2016)

T 252 om-12 "pH and electrical conductivity of hot water extracts of pulp, paper, and paperboard" (July 17, 2016)

T 211 om-12 "Ash in wood, pulp, paper and paperboard: combustion at 525 degrees C" (July 28, 2016)

T 819 cm-07 "Water absorption of corrugating medium: boat method" (July 29, 2016)

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.

T 602 cm-06 "Analysis of sulfuric acid" is out of balance, and requires members that are not representing the 'Producer' interest group.

T 438 cm-06 "Zinc and cadmium in paper" requires two more SSIG members for ballot.

T 504 "Glue in paper (qualitative & quantitative determination)" requires two more members that are not representing the 'Producer' category.

T 611 "Analysis of bleaching powder, calcium hypochlorite bleach liquor, and bleach sludge" requires one more member to ballot.

If no progress is made on these ballots, then they might be considered for withdrawal at the next QSMC meeting. If you have an interest in becoming a member of either of these SSIGs please contact standards@tappi.org.

New TIP Proposals

The Power and Recovery Subcommittee have proposed two new TIPs:

Sodium Sulfate (Sodium Thiosulfate) and Reduction Efficiency Measurement of Green Liquor in Chemical Recovery Processes - this TIP will review available methods for measurement of sulfate and thiosulfate ions in green and white liquors for reduction efficiency calculation, addressing the latest measurement techniques and the potential economic returns of a good reduction efficiency in kraft mills

Recommended Practice for Refractory Selection and Installation in Recovery Boilers - this TIP will address practices to optimize refractory life including proper material selection, installation methods, curing time, and repair methods.

If you are interested in being a part of the Working Group for these new TIPs, please contact standards@tappi.org by July 15, 2016.
