2 California DUI Breath Test Results within .02% of each other?

California DUI Attorney - Recommended Standard for Breath Testing

At least two separate breath samples should be collected and analyzed individually in performing any quantitative evidential breath-alcohol analysis.

The breath samples should be collected at intervals of not less than 2 nor more than 10 minutes, after an initial deprivation period of at least 15 minutes.

Reported breath-alcohol analysis results shall be truncated to two decimal places; and all results obtained shall be reported. Consecutive breath-alcohol analysis results within 0.02 g/210 L. without regard to sign, shall be deemed to be in acceptable agreement.

A HISTORY of THE COMMITTEE ON ALCOHOL AND OTHER DRUGS (CAOD)

RECOMMENDATION OF THE SUBCOMMITTEE ON TECHNOLOGY
DUPLICATE BREATH ALCOHOL TESTING
October 1986

Background on the Committee

The Committee on Alcohol and Other Drugs, first known as the Committee on Tests for Intoxication, was established in the National Safety Council in 1936. From that time, the Committee has been active in making recommendations for the control of the drinking-driving problem, including legislation, enforcement, education, chemical testing equipment, training of testing personnel, and other aspects of alcohol countermeasures programs. Its role had been limited to developing recommendations and standards, but its members have been active in assisting in many aspects of programs designed to reduce the drinking-driving problem. In fact, many of the members, past and present, have been directly involved as officials in programs.
There have been numerous contributions by individual members of the Committee, such as the development of breath testing devices and methods for blood and urine tests that have been widely used. These contributions, which include numerous scientific articles and papers on the subject of chemical tests, have added greatly to the total sum of knowledge in this important scientific effort.
This report attempts to present in condensed form most of the recommendations, standards, and work of the Committee for the past six decades.
