CHAPTER II

APPROVAL OF ANALYTICAL METHODS

Section 1. Method Evaluation.

1. (a) Alcohol free samples shall have an alcohol concentration of less than 0.005% when analyzed by the method.
2. (b) The method shall have an accuracy of + or - 5% of the alcohol value, or + or - 0.005% if the alcohol concentration is less than 0.100%.
3. (c) The method shall not be susceptible to significant interference by substances other than alcohol.
4. (d) The state agency shall keep a complete description of the method on file.

(e) Upon satisfactory demonstration of (a), (b) and (c) above an approved procedure sheet or checklist will be issued by the state agency.

Section 2. Breath alcohol analyses.

(a) Instruments used for quantitative breath alcohol analyses must be capable of presenting a specimen of deep lung breath (substantially alveolar in composition) for analysis. (b) Loss of alcohol (from the breath specimen) through condensation shall be prevented. (c) Results shall be reported as percent alcohol concentration, which is grams of alcohol per two hundred ten (210) liters of breath. (d) Substances which are produced endogenously and appear in the breath shall not contribute to the apparent alcohol concentration by more than (0.005\%). (e) Instruments which singly or in combination collect a deep lung breath specimen and temporarily store the specimen or its contained alcohol and subsequently complete the analysis (remote sampling devices) shall meet all stated performance requirements. Such instruments (remote sampling devices) shall be designed so that the result obtained is independent of barometric pressure or designed so that the result obtained is correctable for barometric pressure change if such correction is necessary. (f) The state agency may include ease of use, maintenance, suitability for field use, etc. in their evaluation. (g) Breath test units must be on the qualified or conforming products list of the Department of Transportation at the time of evaluation.
