Alcance y aplicabilidad

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.

Requisitos técnicos

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.

Métodos de ensayo

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.
