T 625 "Analysis of soda and sulfate black liquor"

Print this article | Send to Colleague

Although there is already a Standard-Specific Interest Group for currently withdrawn TAPPI T 625 "Analysis of soda and sulfate black liquor," the working group chair for a proposed revision and reinstatement of this standard has requested an announcement to recruit additional interested parties.

The proposal is to revise and reissue T 625 as a Classical Method and to add a non-numeric precision statement based on: (1) the test method is primarily being used within a single pulp mill as black, green, and white liquors are not commercially traded; (2) there are several test procedures within this single test method and dividing them into several individual methods would serve no purpose as this is best left as a broad analysis method; and (3) it is extremely difficult to run a round robin for this type of method.

If you would like to join the SSIG for T 625 (or if you need confirmation that you are already a member), please contact standards@tappi.org no later than July 15, 2013.
