A test of a person's breath for alcohol
concentration shall consist of the person
insufflating end-expiratory air samples at least
twice into the instrument, sufficient to allow two
separate measurements. There will be sufficient time
between the provision of each sample to permit the
instrument to measure each sample individually. Two
valid breath samples, provided consecutively, will
constitute one test.
The instrument will perform this test according
to the following protocol when being employed to
quantitatively measure an individual's breath
alcohol concentration. Successful compliance with
each step of this protocol is determined from an
inspection of the printout of results. These steps
are necessary to ensure accuracy, precision, and
confidence in each test.
Step 1. Data entry.
Step 2. Blank test with a result of .000.
Step 3. Internal standard verified.
Step 4. First breath sample provided by
subject.
Step 5. Blank test with a result of .000.
Step 6. External standard simulator solution
test. The result of this test must be between .072
and .088 inclusive.
Step 7. Blank test with a result of .000.
Step 8. Second breath sample provided by
subject.
Step 9. Blank test with a result of .000.
Step 10. Printout of results. |
