本SAE标准制定了零容忍呼气酒精检测系统的性能规范，以降低在酒精影响下驾驶的风险。它定义了呼吸酒精浓度（BrAC）测量的准确性和精密度要求，以及测试这些要求的可接受标准和关键参数。此外，本标准规定了系统对乙醇敏感性、响应时间以及系统在整个车辆寿命期间可能遇到的电气、机械和环境条件的性能要求。

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.
