Compliance overview
Scope and applicability
This standard is applicable to the examination of blood and breath alcohol concentration for vehicle drivers, encompassing both motor and non-motor vehicle operators. It is mandatory for legal enforcement and traffic safety assessments in China. The standard specifically sets the thresholds for driving under the influence and does not apply to non-driving individuals.
Technical requirements
GB 19522-2024 establishes the mandatory alcohol content thresholds for vehicle drivers. It categorizes offenses into two tiers: driving after drinking and drunk driving, based on specific Blood Alcohol Concentration (BAC) limits measured in mg/100mL. The standard also defines the mathematical conversion ratio between breath alcohol concentration and blood alcohol concentration. A precise conversion factor of 1:2200 is mandated to calculate BAC from breath samples, ensuring consistency in legal enforcement. Additionally, the document outlines the general provisions for examination, specifying that testing must be conducted using either breath or blood analysis. It explicitly removes previous methodologies like saliva testing and human balance tests, focusing entirely on quantitative chemical analysis.
Testing methods
The standard mandates two primary testing methods: breath alcohol testing and blood alcohol testing. Breath testing must be conducted using breathalyzers that comply with the technical specifications of GB/T 21254. Blood alcohol testing procedures must strictly follow the methodologies outlined in GB/T 42430, which involves the quantitative determination of ethanol in biological samples. Compliance with these referenced testing standards is mandatory for legal validity.
FAQs
What are the specific legal BAC thresholds under GB 19522-2024?
The standard sets the BAC threshold for driving under the influence at 20 mg/100mL, and for drunk driving at 80 mg/100mL. These thresholds are mandatory for legal enforcement by traffic police.
Are there any updates from the previous version of GB 19522?
Compared to the 2010 version, this edition removes the requirements for saliva alcohol testing and human balance tests. It also updates the definitions and refers to the newer standard GB/T 42430 for blood alcohol testing procedures.
How does GB 19522-2024 affect breathalyzer manufacturers?
The standard mandates that breathalyzers used for enforcement must comply with the technical indicators specified in GB/T 21254. Manufacturers must ensure their devices meet this referenced standard to be legally valid for traffic enforcement in China.
