What does it mean when a measurement is considered "Out of Tolerance" in relation to the ethanol gas standard?

When a measurement is classified as "Out of Tolerance" concerning the ethanol gas standard, it signifies a deviation from the expected target value that falls outside acceptable limits. This means that the measurement either exceeds the permissible threshold or falls below it, indicating that the device's calibration may be compromised, or the measurement process may have issues. Specifically, the definition states that the measurement is not within 5% or 0.005 g/210 L of the target value, ensuring that any value that strays beyond these limits requires attention.

This understanding of "Out of Tolerance" is crucial for the accuracy and reliability of the Intoxilyzer 9000 system, as it underpins the validity of breath alcohol concentration readings used in legal and law enforcement contexts. Ensuring measurements remain within established tolerances is vital for maintaining the integrity of DUI testing standards.
