(1) "Accuracy" means the proximity of a
measured value to a reference value.
(2) "Alcohol" means the unique chemical
compound ethyl alcohol.
(3) "Blank test" means the testing of an
instrument to ensure that no alcohol from a previous
test can interfere with a person's breath test.
(4) "Concentration" means the weight amount of
alcohol, expressed in grams, contained in two
hundred ten liters of breath or alcohol/water vapor.
(5) "Data entry" means the process of providing
information through a keyboard to the instrument for
the purposes of (a) identifying a breath test
document to an individual and (b) statistical
analysis.
(6) "Interference" means a test result whose
infrared absorbance properties are not consistent
with ethanol.
(7) "End expiratory air" means the last portion
of breath to be delivered to the instrument once the
appropriate sample acceptance criteria have been
met.
(8) "External standard test" means the use of a
simulator containing a certified simulator solution,
to provide a known alcohol vapor concentration to
test the accuracy and proper working order of the
instrument. This test of the function of the
instrument is performed with every breath test. The
external standard test does not calibrate the
instrument.
(9) "Internal standard test" means the use of a
quartz filter to provide a check that the instrument
has maintained calibration since the last time
calibration was performed and is in proper working
order at the time of the test.
(10) "Precision" means the ability of a
technique to perform a measurement in a reproducible
manner.
(11) "Simulator" means a device which when
filled with a certified simulator solution,
maintained at a known temperature, provides a vapor
sample of known alcohol concentration.
(12) "Valid breath sample" means a sample of a
person's breath provided in such a manner to be
accepted for analysis by the instrument. |
