Breath Testing in Texas: A New Paradigm Standard Operating Guidelines – Visit the website for Voice for the Defense Online to learn more about the Texas breath alcohol testing programs and find its recently adopted formal written “Standard Operating Guidelines” (SOG) for technical supervisors to follow in the operation of some aspects of the breath test program. The lack of any written policies and guidelines has subjected the Texas alcohol testing program to criticism. The new administrative regulations provide that approval of breath alcohol testing programs is contingent on each program agreeing “to conform and abide by any directives, orders, or policies issued or to be issued by the scientific director regarding any aspect of the breath alcohol testing program.”
Standard Operating Guidelines for Evidential Breath Alcohol Instrument Calibration – Visit the Texas Breath Alcohol Testing Program, Office of the Scientific Directory to find the Directive from the Scientific Directory at OSD-CAL-O1, Version 6, effective on 06/01/2016. The SOGs describe the procedure for breath alcohol instrument calibration and the calculations used to establish the combined uncertainty. Any changes which occur as a result of the implementation of these guidelines apply only to calibrations which are completed on or after the effective date of this document.
