Special note: Documents appearing in the TAPPI online version of the Standards, TIPs, and Useful Methods are updated once a month (usually around the 30th). 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, TIPs, and Useful Methods and you are in a hurry for new documents that have not yet been posted, you can send a request for TIPs to tip@tappi.org or for Standards and Useful Methods to standards@tappi.org.
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 845 om-20 Wet pin adhesion of corrugated board by selective separation (February 5th, 2025)
T 401 om-20 Fiber analysis of paper and paperboard (February 23rd, 2025)
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 the draft in ballot. If you would like to participate in the SSIGs that review and vote on the Standards, please contact TAPPI Standards Department at standards@tappi.org.
Getting started is easy. Do you have just a general idea for a Standard, or are you farther along and have a substantial draft? If you just have a general idea for a Standard or TIP, complete the New Idea Submission form. TAPPI will review your idea and identify an appropriate committee or group to work on your suggestion. If you are further along, send an initial draft to standards@tappi.org. From there, the TAPPI Standards Manager will guide you through the appropriate process to finalize and approve the new document.
Withdrawal of TIP 1205-02
TIP 1205-02 Cotton in nonwovens has been withdrawn due to lack of relevancy in the industry. This Automatically Periodically Reviewed TIP is required to be reviewed every 10 years.
Withdrawn TIPs are available free for TAPPI members and for a $10 charge to nonmembers.
To initiate the reinstatement process for withdrawn TIPs, please contact tip@tappi.org to open a Work Item.
This TIP, Technical Information Paper, is provided to assist in evaluating the performance of single-stage, liquid ring vacuum pumps. Cone ported liquid ring vacuum pumps are a common source of paper machine vacuum in the pulp and paper industry. This paper is also applicable to other designs of single-stage liquid ring vacuum pumps such as flat plate ported.

... that to participate in the balloting process for TAPPI Standards you must sign up for the Standard-Specific Interest Groups (SSIGs)? Drafts are available for anyone to review, but to vote you must be a member of the SSIG. Each Standard has its own SSIG – so you have to sign up for each Standard that you have an interest in. Links to all of the SSIGs (by subject category) can be found on the SSIG Join Page. When you click on a Subject Category, it will display links to related SSIGs.
For details on these commonly used acronyms in the development of TAPPI Standards and TIPs, please see the Standards Guidelines and the TIP Guidelines, or send your questions to standards@tappi.org.

The TAPPI CD of Standards, TIPs, and UMs has been discontinued since 2021. An Individual or Company License for access to the continually updated collection of Standards, TIPs, and UMs via the web is the best way to always have a current set of documents accessible. A print-on-demand version of either the Standards, TIPs, or UMs, current and updated as of the date printed, is also available.
