In-Car Air Pollution Detection and Control Solution
First, the Current Situation and Challenges
With cars becoming more common in households, China's automotive industry has seen rapid growth. However, concerns about air quality inside vehicles have also risen significantly. In 2006, the Indoor Air Monitoring Center of the China Interior Decoration Association conducted tests on over 200 vehicles and found that nearly 90% exceeded safe levels of harmful substances such as formaldehyde, benzene, and ketones. These pollutants can lead to long-term health risks, even posing a serious threat to life. As consumer complaints increase, stricter regulations are expected to be introduced soon.
Second, the “Standard Sampling Method for Volatile Organic Compounds and Aldehydes and Ketones in Vehiclesâ€
In March 2007, the State Environmental Protection Administration released a draft of the “Measurement Method for Air Pollutants in Vehicles†to various ministries, environmental agencies, car manufacturers, and related institutions. This marked an increased focus on vehicle interior pollution, which directly affects the health and safety of drivers and passengers. On December 7th, the administration officially issued the standard “Method for Sampling and Determination of Volatile Organic Compounds and Aldehydes and Ketones in Vehicles,†with the number HJT400-2007. Developed by the Science and Technology Standards Department, this standard was drafted by environmental monitoring agencies and major automakers, and took effect on March 1, 2008. It sets clear guidelines for testing procedures, including sampling locations, environmental conditions, and specific methods. Non-compliant products or companies may face strict penalties, ensuring the standard becomes a mandatory requirement for the industry.
Third, Detection and Control Solutions
Based on the HJT400-2007 standard, new vehicles must pass air quality tests before being sold. Automakers need to ensure that all interior components—such as seats, dashboards, and roofs—are free from harmful emissions. These materials often release volatile organic compounds like benzene and formaldehyde, which can be dangerous to health. To address this, manufacturers must conduct thorough testing of these materials to ensure compliance with safety standards.
Currently, atomization testers are widely used to detect volatile substances in vehicle interiors. Materials like leather, plastics, and adhesives can emit harmful gases when temperatures rise due to sun exposure or engine operation. These gases can condense on windows, reducing visibility and affecting driving safety. To prevent this, automotive companies perform atomization tests, and materials exceeding the fogging limits are not used. Major manufacturers like GM and Volkswagen have already set their own internal standards for this purpose.
The FT-F1 atomization tester, launched by Jinan Languang in 2005, is designed according to international standards such as DIN 75201, ISO 6452, and SAE J1756. It simulates temperature increases inside vehicles to evaluate the fogging performance of interior materials. The equipment uses high-quality components and offers excellent cost-effectiveness compared to imported alternatives. Its reliability and performance have made it popular among many automotive manufacturers, helping reduce reliance on foreign equipment. This technology is now widely used in factories like Takata (Shanghai) Auto Parts Manufacturing Co., Ltd. and others, providing an effective solution for interior material testing.
Fourth, Conclusion
The introduction of the “Sampling and Determination Methods for Volatile Organic Compounds and Aldehydes and Ketones in Vehicles†brings a legal framework for air quality control in cars. This ensures better protection for consumers and promotes higher standards across the automotive industry. As China’s automotive sector continues to grow, Labthink Languang, a leading domestic testing equipment manufacturer, is committed to supporting automakers and suppliers in improving interior air quality. Their range of non-metallic testing instruments plays a crucial role in ensuring safer and healthier driving environments for everyone.
