In-car air pollution detection and control solution
In-Car Air Pollution Detection and Control Solution
First, the Current Situation and Challenges
With the increasing popularity of cars in households, China's automotive industry has experienced 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% had excessive levels of harmful substances such as formaldehyde, benzene, and ketones, according to indoor air quality standards. These pollutants can cause health risks without people even realizing it, and in severe cases, they may lead to long-term health damage. As consumer complaints increase, the need for stricter regulations is becoming more urgent.
Second, the “Standard Sampling Method for Volatile Organic Compounds and Aldehydes and Ketones in Vehicles†Standard
In March 2007, the State Environmental Protection Administration released a draft of the “Measurement Method for Air Pollutants in Vehicles†to relevant ministries, environmental monitoring departments, and major car manufacturers. This marked a growing emphasis on in-car air 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 and drafted by environmental monitoring agencies and several automobile companies, this standard was implemented on March 1, 2008. It provides a uniform framework for testing vehicle interior air quality, including sampling points, environmental conditions, and testing procedures. The key aspect is that this standard is legally binding, and non-compliant products or companies may face serious consequences.
Third, Detection and Control Solutions
To meet the requirements of the HJT400-2007 standard, car manufacturers must ensure that new vehicles pass air quality tests. The main sources of indoor pollution come from volatile organic compounds emitted by materials like adhesives, fabrics, and plastics used in seats, dashboards, and roofs. Therefore, automakers must test these materials thoroughly before production. Testing helps identify harmful emissions and ensures that vehicle interiors meet safety and quality standards.
Currently, atomization testers are widely used to detect volatile substances in automotive interior materials. Materials such as leather, plastic, fabric, and adhesives may release harmful gases when temperatures rise due to sunlight or engine operation. These gases can condense on windows, reducing visibility and affecting driving safety. To address this, atomization tests are essential. Any material exceeding the fogging limit is not used in vehicle interiors. Major manufacturers like GM and Volkswagen have already set strict guidelines for these parameters.
The FT-F1 Atomization Tester, introduced by Jinan Languang in 2005, is designed according to international standards like DIN 75201, ISO 6452, and SAE J1756. It simulates temperature increases inside vehicles to evaluate the fogging performance of interior materials. With high-quality components and excellent cost-effectiveness, it offers a competitive alternative to imported equipment. Its reliability and performance have made it popular among many auto manufacturers and suppliers, helping to reduce reliance on foreign technology. This device is now widely used in factories such as Takata (Shanghai), Blonde Co., Ltd., and Shiyan Dongfeng Automobile.
Fourth, Conclusion
The introduction of the “Sampling and Determination Methods for Volatile Organic Compounds and Aldehydes and Ketones in Vehicles†standard provides a legal basis for air quality control in vehicles. This will better protect consumer rights and ensure safer purchasing decisions. At the same time, it encourages improvements in the quality of both car manufacturers and their suppliers. Labthink Languang, a leading domestic testing equipment manufacturer, is committed to working with automotive companies to solve these challenges. As China’s automotive industry continues to grow, Labthink’s range of non-metallic testing instruments will play an important role in ensuring the safety and quality of vehicle interiors and air environments.
