The concentration of volatile organic compounds in the interior of only three models exceeds the standard at the time of the initial inspection. Excess VOCs are formaldehyde or acetaldehyde. The national standard requires the concentration of formaldehyde to be ≤0.10 mg/m3, and the concentration of acetaldehyde to be ≤0.05 mg/m3. The formaldehyde detection value of the detected Great Wall H6 was 0.344 mg/m3, and the acetaldehyde detection values ​​of Dongfeng Honda Civic and Dongfeng Peugeot 508 were 0.054 mg/m3 and 0.068 mg/m3, respectively. In addition to the three vehicles exceeding the standard, although other models have detected formaldehyde and acetaldehyde, they are within the concentration range required by the national standards, and almost all other six volatile organic compounds are not detected. The compliance rate is 93.02%. . Subsequently, the organizer tested the new car of the same model according to the re-inspection applications of the three non-compliance companies.
