1 Scope

This regulation is applicable to the first verification, subsequent verification and in-use inspection of the exhaled gas alcohol content detector.

2 Reference documents

This regulation refers to the following documents. GB/T 21254-2017 Exhaled gas alcohol content detector For dated references, only the dated versions are applicable to this Regulation; for those without dates The latest version (including all amendments) is applicable to this regulation.

3 Overview

Exhaled breath alcohol content detector (hereinafter referred to as wine detector) is used to detect the alcohol content in human exhaled breath the amount. The wine detector consists of gas circuit, control circuit, alcohol sensor, breath detection system, sampling system and display printing system And other components. According to the measuring principle, the wine detector can be divided into battery type (ie electrochemical type), semiconductor type and infrared type.

4 Measurement performance requirements

4.1 Indication error The display error of the wine detector should meet the requirements of Table 1. Table 1 Indication error requirements First verification and subsequent verification (-0.040 ~ 0) mg/L Or relative error -10% ~ 0 Just one of them (-0.060 ~ 0) mg/L Or relative error -15% ~ 0 Just one of them 4.2 Repeatability The repeatability of the wine detector should meet the requirements of Table 2. Table 2 Repeatability requirements First verification Follow-up verification and inspection in use ≤1.7% ≤2.5% 4.3 Drift Zero drift. no more than 0.010mg/L. Indication drift. The indication drift at 0.4mg/L measurement point does not exceed 0.010mg/L. 4.4 Anti-interference ability ......
