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. TAPPI members can view any drafts that are in ballot by logging in to the TAPPI web site (www.tappi.org), clicking on "My TAPPI," and then clicking on the "Standards Public Draft Review" link on the left side of the page. If you would like to review and comment on any draft and are not a member of the corresponding Standard-Specific Interest Group (SSIG), you may view the draft on line or you may request a copy of the draft being balloted by writing to standards@tappi.org. TAPPI members may join SSIGs as permanent members; go to the Subject Category page to download forms for this purpose. Nonmembers of TAPPI may join any SSIG as a voting member; to do so, send a message to standards@tappi.org to receive a copy of the draft and a 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.

Standards Coming Up For Review

The system for review and development of TAPPI Standards requires an announcement of review dates so that any interested TAPPI parties may access the drafts, submit comments, and/or join the Standard-Specific Interest Group (SSIG) to cast an official vote.

Listed below are the Standards that will be up for review in 2013. The date indicated is the target date on which the draft will be posted for review by TAPPI members in the Members Only section of the TAPPI website. On that date, you may go to the home page (www.tappi.org), log on with your member ID and password, place your cursor over "Membership," and select "My TAPPI" from the dropdown box. When your personal page appears, click on the "Standards Public Draft Review" link on the left-hand side. You do not have to be a member of the Standard Specific Interest Group to comment on the draft.

Nonmembers of TAPPI who wish to be part of the voting for any Standard should send a message to standards@tappi.org and request voting membership on the corresponding SSIG, prior to the target ballot date, if possible. Anyone who joins the SSIG before the target balloting date will receive a notice of the ballot. Nonmembers cannot access the drafts online, but they will be sent copies by email upon request after receiving the notice of ballot by email.

If you have joined the Standard Specific Interest Group for any Standard, you will receive a notice for ballot at the proper time with instructions for casting your vote and making your comments. If you wish to join the Standard Specific Interest Group for a particular Standard, please go to the Subject Categories for Standards page or contact the Standards Department at TAPPI (standards@tappi.org ), or phone +1-770-209-7276 or fax +1-770-446-6947).

Proposed new standard for analysis of starch in paper or paperboard

A proposal has been made for a new standard test method: "Starch in paper or paperboard." This new standard would replace the withdrawn standards T 531 "Starch consumption in corrugated board (enzymatic/gravimetric method)" and T 532 "Starch consumption in corrugated board (enzymatic/colorimetric method)."

The scope of the method is: This standard test method provides the procedure for the analysis of starch content in paper or paperboard, either as an internal or sizing additive or as a component of starch adhesive in lamination or corrugated board.

A Standard-Specific Interest Group (SSIG) must be formed for this proposal. Any individuals who are interested in this Standard may join the SSIG to receive ballots when this method is ready for vote. If you would like to join the SSIG for this project, please notify the Standards Department at standards@tappi.org or by fax at +1-770-446-6947 no later than February 18, 2013.

Proposed new standard for roughness using a sharp-tipped stylus

A proposal has been made for a new standard test method: "Roughness of paper and paperboard, stylus (Emveco sharp tip-type) method" This new standard would be a companion piece to T 575 "Roughness of paper and paperboard, stylus (Emveco-type) method," which uses a flat stylus. The new method uses a sharp-tipped stylus.

The scope of the method is: This method measures the surface roughness of paper and paperboard used in contact printing processes. It may not be used for tissue or creped paper and may not be suitable for newsprint that is inspected for visual anomalies which cannot be detected with this equipment. The method is not useful for measuring surface waviness. This method uses a sharp-tipped stylus to mechanically trace the paper surface which differs from methods that relate the rate of air flow leakage to paper roughness.
