Section 73-2 - Methods of Making Chemical AnalysesA. Methods. SLED shall approve such methods of performing chemical analysis as are demonstrated to the satisfaction of SLED to produce accurate and reliable determinations of alcohol concentration in a reasonable, convenient, and efficient manner.B. Breath-Testing Devices. SLED hereby approves the method of performing chemical breath analysis to determine alcohol concentration by using breath-testing devices. SLED will consider for approval only devices that first have been tested and approved for their accuracy and reliability by the National Highway Traffic and Safety Administration of the United States Department of Transportation. All approved devices will be specified in the SLED Policy and Procedures Manual.C. Certifications. SLED shall certify each breath-testing device. This certification shall include the calibration of the device with an external standard and the verification of the device's calibration with an internal and or external standard. Whenever a breath-testing device is certified, this certification will also constitute an inspection of the breath-testing device. For an instrument whose testing station is a mobile van, once the instrument is certified for use in the van, it remains certified regardless of the physical location of the van. Additionally, the certification tests and certification do not have to be repeated if the instrument and or its software are upgraded.D. Inspections. SLED shall inspect each certified breath testing device (either remotely via computer modem or on-site) at least once every three months. In addition, an inspection is performed after any repair is completed. This inspection shall include the verification of the device's calibration with an internal and/or external standard. The inspection may begin before three months has elapsed and not be completed until after the three-month period. In this case, the time lapse between inspections may exceed three months. This occurrence is acceptable as long as no subject tests are performed until the inspection is completed. Therefore, at least one SLED inspection must be performed in the three months before a subject test. Failure to have an inspection within the required time does not cause revocation of certification for that instrument but signifies that proper procedures for that time were not followed.E. Records. Certification, inspection, and database records shall be maintained by SLED for a minimum of five years. However, the accidental/unavoidable loss of data does not invalidate any breath tests.Amended by State Register Volume 7, Issue No. 5, eff May 27, 1983; Amended by State Register Volume 8, Issue No. 7, eff July 27, 1984; State Register Volume 24, Issue No. 4, eff April 28, 2000.
