New or Revised Standards, TIPs, and Useful Methods

Here is the list of TAPPI Standards recently approved as American National Standards:

New American National Standards:

T 419 om‐18 Starch in paper
T 452 om‐18 Brightness of pulp, paper, and paperboard (directional reflectance at 457 nm)
T 536 om‐18 Resistance of paper to passage of air (high‐pressure Gurley method)
T 830 om-18 Ink rub test of containerboard and corrugated board
T 1210 sp‐18 Units of measurement and conversion factors

Approved reaffirmation of current American National Standards:

T 212 om‐18 One percent sodium hydroxide solubility of wood and pulp
T 262 sp-18 Units of measurement and conversion factors
T 464 om‐18 Diffuse brightness of paper, paperboard and pulp (d/O) (ultraviolet level D65)
T 547 om‐18 Air permeance of paper and paperboard (Sheffield method)

Approved revision of current American National Standards:

T 839 om‐18 Edgewise compressive strength of corrugated fiberboard using the clamp method (short column test) 
T 1216 sp‐18 Indices for whiteness, yellowness, brightness, and luminous reflectance factor


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.

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 a draft in ballot.

 
SSIG Members Needed

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:
 
SSIGs that need 1 member:
T 255 Water-soluble sulfates in pulp and paper
T 256 Water-soluble chlorides 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
T 572 Accelerated pollutant aging of printing and writing paper by pollution chamber exposure apparatus (needs 2 more members with interest categories different from General Interest)

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. (4 members needed)
 
Participating in a SSIG is free and open to any industry expert interested. Join now!

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
 
Volunteers for the following Subject Categories of Technical Information Papers (TIPs) are needed:

0301 - Safety
0304 - Process Control & Quality Assurance
0305 - Production
