Annual Inspections Done Without Reference to Manufacturer's Specifications


Purpose:

To confirm that when new instruments are being evaluated, various solutions are used between 50 and 400 mg/100mls.

To confirm that when new instruments are being evaluated, the specified accuracy requirement is +/- 5 percent of the BAC with a precision requirement of +/- 3 mg/100mls under 100 mg/100mls and +/- 2.5 percent for readings greater than 100.

To confirm that the purpose of such evaluation is to ensure the accuracy and reliability of breath tests.

This process is "type approval" in the international literature.

To obtain an admission that the manufacturer advertises that its instrument is accurate plus or minus 3 milligrams per 100 mls and standard deviation doesn’t exceed 3 milligrams per 100 mls.

To obtain an admission that under the ATC Best Practices document, new instruments must be individually inspected before being placed into service to ensure that they initially meet the manufacturer's specifications.

This process is "initial verification" in the international literature.

To obtain an admission that under the ATC Best Practices document, instruments in service must be individually inspected, periodically, to ensure that they continue to meet the manufacturer's specifications.

This process is "subsequent verification" in the international literature.

To obtain admissions as to the manufacturer's specifications for accuracy and precision in its advertising, in the information given to the evaluator during type approval, and in the servicing/maintenance documents given to the people who do work on these instruments on a regular basis.

To obtain an admission that although the local police service appears to be doing annual and periodic inspections, they are doing so without reference to the manufacturer's specifications for accuracy and precision across the measuring interval of the instrument.
