We extend our special appreciation to the following volunteers who served as Working Group Chairs in the recently published reviews of TAPPI TIPs: 

Margaret Gorog - WGC for TIP 0402-13

Special note: Documents appearing in the TAPPI online version of the Standards and TIPs 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 and TIPs 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 to standards@tappi.org.

Title: Basic Density and Moisture Content of Pulpwood

This method describes the measurement of the basic density (bone-dry weight per unit of maximum volume) of pulpwood in the form of chips or disks from the cross-section of logs.  The method also gives procedures for determining the moisture content of wood in either form.

Any interested individuals 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.

If you would like to know more or join the U.S. TAG to ISO TC 6, please write to isotc6@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.

... 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.

Details on how to search and order TAPPI Standards, TIPs, and Useful Methods can be found on the TAPPI website’s Search and Order page.

All individual TIPs or Standards are available for electronic or paper delivery. For electronic delivery, the documents are e-mailed in PDF format.  Hard copy documents can be mailed or faxed, but shipping and handling costs will apply.

For Individual TIPs, order Item Number: 0108____ (Insert TIP number)
For Individual Standards, order Item Number: 0104T____ (Insert Standard number)
For individual Useful Methods, order item number: 0104UM_____ (Insert UM number)

List price: $57; TAPPI member price: $38. There are no shipping or handling charges for electronic documents.

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.

For information and quotes on company licenses, contact TAPPI Press (press@tappi.org) or +1-770-209-7277. For regular orders (including individual online licenses), contact Member Connection at 1-800-332-8686 (US), 1-800-446-9431 (Canada), or +1-770-446-1400 (international), or order online at www.tappi.org.
