Le présent document décrit des méthodes permettant de déterminer la vitesse et le sens d'écoulement de l'air, les concentrations en monoxyde de carbone (CO), en oxyde d'azote (NO) et en dioxyde d'azote (NO2), et la visibilité dans les tunnels routiers à l'aide d'instruments à lecture directe. Il exclut spécifiquement les exigences relatives aux essais de conformité des instruments.
