Breath-Based Alcohol Detection System
J3214_202305
This SAE Standard establishes the performance specifications for the zero-tolerance breath alcohol detection system to reduce the risks of driving under the influence of alcohol. It defines the accuracy and precision requirements of the breath alcohol concentration (BrAC) measurement, as well as the acceptability criteria and key parameters to test these requirements. Additionally, this standard sets the performance requirements of the system for ethanol sensitivity, the response time, and the electrical, mechanical, and environmental conditions the system may encounter throughout the lifespan of the vehicle.
Rationale:
Since its publication, we have been performing testing against the standard and have identified sections in the standard that require revisions and clarifications. These sections did not contain all the necessary information to successfully conduct the tests against the standards.
