Odyssey held a special meeting: Strengthening the Fire Safety Line of Automotive Interior with Professional Testing-Chemical Instrument Network

In response to the industry discussion caused by the high-speed collision and spontaneous combustion accident of Xiaomi SU7 in Chengdu on October 13th, Shenzhen Odyssey Chuang Precision Instrument Co., Ltd. held a special meeting on automotive interior flame retardant safety on October 15th. The conference combines the painful lessons of the rapid combustion of interior materials in accidents that exacerbated the disaster situation, systematically expounds the core value of flame retardant performance testing, and calls on the entire industry to strengthen material safety control.

Accident sounds alarm: interior flame retardant becomes key variable for escape

The opening of the meeting directly pointed to the core pain points of the Xiaomi SU7 accident that has recently attracted attention. Li Gong, the Technical Director of Odyssey Creation, cited research data in the field of fire rescue and pointed out that "when the battery of new energy vehicles loses control, the temperature can reach over 1000 ℃, and the thermal diffusion speed can reach 20cm/s. The flame retardant performance of interior materials directly determines the width of the escape window. ”According to calculations, if the combustion rate of interior materials exceeds 100mm/min (GB 8410-2006 standard limit), the flame can cover the entire cabin within 15 seconds, and the concentration of hydrogen cyanide (HCN) released exceeds 50ppm, causing acute poisoning in humans, which is 20 times more toxic than carbon monoxide.

In this accident, the initial fire caused by the damaged battery pack could have been delayed by high-quality flame-retardant materials, but the rapid spread of interior combustion quickly sealed the escape route. Li emphasized that this is precisely the core reason why flame retardant testing must run through the entire process of research and development and production.

Standard iteration acceleration: Detecting technology to solve industry pain points

In response to the current implementation status of flame retardant standards, the meeting elaborated on the development trend of domestic and international standard systems. Mr. Zhang, the quality manager of Odyssey, introduced that the new regulations of GB 8410 in the 2025 version of China have upgraded the testing method from horizontal combustion to 45 degree inclined combustion, added a cone calorimeter test, and required the peak heat release rate to be ≤ 150kW/m ², which is 40% stricter than the old standard. The EU ECE R118 standard includes assessment indicators such as smoke density (transmittance ≥ 100%) and toxic gas index (≤ 1.0), which puts higher requirements on detection technology.

As an old enterprise in the domestic production of instruments and equipment for 20 years, Odyssey Chuang showcased its core solution at the conference: the hot wire tester can simulate the ignition characteristics of materials in high temperature environments of 550 ℃ -960 ℃, and the horizontal and vertical combustion tester accurately captures the flame spread trajectory and smoke density changes through high-speed cameras and AI algorithms at a thousand frames per hour. Our equipment has achieved synchronous detection of 12 parameters such as combustion speed, self extinguishing time, and toxic gas concentration. Companies such as Tesla and Volvo have built material safety assessment systems through similar equipment, "Manager Zhang revealed.

In his summary, Mr. Wang, the General Manager of Odyssey Creation, stated, "As a testing equipment service provider, we have upgraded our intelligent detection system and added a dedicated testing module for battery pack peripheral materials, which can simulate the combustion behavior of materials under stress after collision." It is reported that the system can shorten the evaluation cycle of material flame retardant performance by 40%.
