StammJones-2-225x300Among the speakers listed above was A.W. Jones, the leading expert in the world on blood and breath testing with over 400 published articles, who answered questions from Leonard R. Stamm regarding calibration of breath test equipment and calculating uncertainty.  With respect to calibration, Dr. Jones opined that where a state has different levels of culpability carrying different punishments, such as Maryland, where the Motor Vehicle Administration suspends driver licenses for test result of 0.08 or above but less than 0.15 and for a test result of 0.15 and above, that the state should calibrate its breath testing equipment at both levels.  This is important because Maryland only calibrates its breath test equipment at 0.08.  Dr. Jones also stated that there is currently no accepted protocol for determining uncertainty.  Dr. Jones preferred method for eliminating uncertainty is to take the mean of two measurements and deduct 15% of the mean to attain a certainty of 99.9%.
