introduction
The main technical indicators of this regulation refer to GB/T 21254-2017 "Exhaled Gas Alcohol Content Detector" and
Compared to.2006, the main changes except for editorial changes are as follows.
--- The name of the regulation was changed to "exhaled gas alcohol content detector";
--- Modified the requirements of the "indication error", "repeatability", "anti-interference ability" and "expiratory resistance" (see 4.1,
4.2, 4.4, 4.6);
--- Added "drift" "measurement range, resolution and measurement unit conversion" "exhalation minimum flow rate and shortest hold
"Continuous time" index requirements (see 4.3, 4.7, 4.8);
--- "Memory effect" was changed to "residual memory effect", and the indicator requirements were modified (see 4.5);
--- The "result retention and storage time" item was adjusted to the "result result" in Chapter 5 "General Technical Requirements"
Keep and store "(see 5.4)
--- The verification item of "undervoltage alarm function" has been cancelled;
--- Revised "Verification Environmental Conditions" "Standard Substances and Equipment for Verification" "List of Verification Items" (see
6.1.1, 6.1.2, Table 3);
--- Modified the "indicating error", "repeatability", "anti-interference ability", "memory residual effect", "expiratory resistance" and
Verification method of "Expiratory Time" (see 6.3.3, 6.3.4, 6.3.6, 6.3.7, 6.3.8, 6.3.9);
--- Added "drift", "minimum expiratory flow and shortest duration", "measurement unit conversion", "measurement range"
Verification method (see 6.3.5, 6.3.9, 6.3.10, 6.3.11);
--- Amendment Appendix A "Requirements for Ethanol Standard Gas in Air and Precision Wine Detector" (see Appendix A);
--- Added Appendix B "Method and Requirements for Traceability of Ethanol Gas Concentration Value Produced by Ethanol Gas Source"
(See Appendix B);
--- Added Appendix C "Exhaled alcohol concentration (mole fraction μmol/mol) and exhaled alcohol concentration
Degree (mg/L) and conversion of blood alcohol concentration (mg/100mL) "(see Appendix C);
--- Deleted Appendix D "Expiratory Alcohol Concentration and Blood Alcohol Concentration Comparison Table".

Verification Regulations of Exhalation Gas Alcohol Content Detector
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
