El presente proyecto de Norma Oficial Mexicana establece los criterios de desempeño, métodos de prueba, métodos de evaluación y procedimientos de verificación para los alcoholímetros evidenciales. Estos dispositivos utilizan aire espirado para detectar y cuantificar la presencia de alcohol con la exactitud e incertidumbre necesaria para fines evidenciales. Adicionalmente se establece la fórmula de equivalencia para determinación de alcohol en sangre a partir de la cuantificación en aire espirado.

This draft Mexican Official Standard establishes performance criteria, test methods, methods of assessment and verification procedures for Evidentials Breath Analyzers. These devices use exhaled air to detect and quantify the presence of alcohol and uncertainty with the accuracy required for evidential purposes. Additionally the equivalence formula for determining blood alcohol is established from quantification in exhaled air. This draft Mexican Official Standard applies to Evidentials Breath Analyzers, imported or marketed in the territory of the United Mexican States and are used for the detection and quantification of alcohol in exhaled air, for purposes of measuring the amount of alcohol ingested allowed for the development of an activity, whether preventive, or punitive reference purposes. It also applies to determine the equivalence of blood alcohol from quantification in exhaled air.
