Public review of TAPPI test methods.The system for review and development of TAPPI TAPPI Technical Association of the Pulp and Paper Industry Test Methods requires an announcement of review dates for methods so that any interested TAPPI members may access the drafts and submit comments.
Listed below are the methods that will be up for review from January 2005 through June 2005. The date indicated is the date on which the draft will be posted for review by TAPPI members in the Members Only section of the TAPPI website. Go to the home page (www.tappi.org), log on with your member ID and password, then click "My TAPPI."
