Press release date: September 3, 2009

W. CONSHOHOCKEN, Pa., September 3, 2009-A workshop on "How to Develop a Precision and Bias Statement" will be held Tuesday, Dec. 8, 2009, at the Hyatt Regency Atlanta in Atlanta, Ga. Sponsored by ASTM International Committee D04 on Road and Paving Materials, the workshop will be held in conjunction with the Dec. 8-10 standards development meetings of the committee. This workshop is the third in a series of how to prepare a precision and bias statement for ASTM standard test methods. Previous workshops have covered why precision and bias statements are needed and how to calculate them. The workshop will cover the process for the initial drafting of a test method and the first ruggedness tests through test procedure revisions, follow-up testing to confirm the adequacy of the revisions, pilot testing of a single material, and finally, an interlaboratory study to prepare the precision and bias statement. Case studies on current ASTM Committee D04 standard test methods will be used to illustrate the process, including what works and what does not work. Online registration opens approximately eight weeks before the workshop and closes Dec. 2. There is no fee to attend the workshop.
