T/CAAMTB 143-2023 Passenger car - Methods for measuring indoor air quality and evaluating odour in the vehicle interior

Scope

Main technical content: This document describes and specifies the whole-vehicle laboratory, indoor air sampling methods, and experimental conditions used to measure volatile organic compounds (VOCs) and aldehydes and ketones in vehicle interiors. The document conducts measurements under three experimental conditions: 1) measuring VOCs and aldehydes and ketones in a simulated environmental condition at 25°C ± 1°C (without air exchange); 2) measuring VOCs and aldehydes and ketones at high temperatures (in parking mode); and 3) simulating the driving of a vehicle after it has been parked in the sun and measuring VOCs and aldehydes and ketones during driving (in driving mode), using fixed-intensity sunlight radiation simulation. The document specifies the experimental equipment, sampling and analysis principles, standard testing processes, indoor pollutant limits and calculations, odor evaluation test procedures, test reports, and quality control for volatile organic compounds and aldehydes and ketones in passenger car cabins. Measurements and evaluations of indoor air in other types of buses and trucks can be carried out in accordance with this document.
