Chinanews.com, Boao, February 14th (Reporter Wang Xiaobin) With the rapid development of the automobile industry, various evaluation indicators such as collision safety, power economy, and energy consumption are important references for consumers to buy a car.
However, there are many brands, various models, and the technical terms are unfamiliar and cold... Many people still choose the "upper body" of difficulties when buying a car.
On February 14th in Boao, Hainan, a new automobile evaluation index - China Automobile Corrosion Resistance and Aging Performance Evaluation Procedure (CA-CAP) released the evaluation results of the first batch of formal evaluation models, and also provided consumers with the best experience in purchasing automobiles. Provide a new dimension of reference indicators.
What is CA-CAP?
CA-CAP is an automobile evaluation project led by Hainan Tropical Automobile Testing Co., Ltd. under the guidance of the China Association for the Promotion of Quality and Safety of Consumer Products, and jointly initiated by more than 20 units including domestic automobile testing institutions and manufacturers.
On February 14th, CA-CAP evaluated the scratches on the right front door of the car.

Corrosion and aging of automobiles will damage the appearance of the product, lead to functional failure, shorten the service life, affect the residual value of used cars, and may cause serious safety accidents.
It often takes 3 years or even longer for a car to be designed, produced, sold, used, and exposed to corrosion problems.

Fu Xiaofeng, deputy general manager of Hainan Tropical Automobile Testing Co., Ltd. and director of the CA-CAP evaluation business department, introduced that the CA-CAP test mainly consists of major facilities such as salt spray spray, high-temperature and high-humidity parking, salt water splash road, salt water tank, and gravel impact. Condition composition, each cycle is 24 hours, and the test cycle is 60 cycles.
The evaluation of test results consists of three first-level indicators of corrosion appearance of parts, paint film scratches and functional evaluation, and several secondary indicators, each of which has a corresponding evaluation score.
Finally, according to the pros and cons of corrosion resistance, they are divided into 0-5 stars, which is convenient for consumers to compare.

Humidity and heat exposure are the key factors affecting the performance of automobiles and the corrosion and aging of parts. Hainan’s unique high temperature, high humidity, high corrosion, and rainy hot and humid climate environment can shorten the verification cycle and highlight the verification effect in terms of weather resistance of automobile products. and other advantages.
Fu Xiaofeng said that he noticed that consumers are particularly concerned about the condition of the vehicle after three or six years of use, so he simulated the worst car use environment and formulated a cycle of evaluation. "10 cycles are equivalent to 1 year, and 60 cycles are 6 years. , each cycle node has an image record, so as to compare and observe the aging degree of metal, plastic, rubber and other materials of the vehicle."
How did the first batch of vehicles tested by CA-CAP perform?
According to Fu Xiaofeng, the first batch of 6 vehicles participated in the CA-CAP evaluation, covering various types of vehicles such as sedans, SUVs, independent vehicles, joint ventures, fuel vehicles, and electric vehicles.
Relevant models are purchased by the evaluation team as ordinary consumers in automobile 4S stores after being approved by the China Association for the Promotion of Quality and Safety of Consumer Products.
The evaluation results show that although there is a gap in the performance of self-owned brands and joint venture brands in terms of automobile corrosion resistance, the products of self-owned brands are gradually catching up with the products of joint venture brands.

According to market user research and statistical data, Chinese consumers are more sensitive to car body scratches and paint scratches, so CA-CAP especially adds the evaluation of car body coating scratches as a bonus indicator.
The results show that the corrosion resistance technology and materials of the door and fender areas of the six tested models are at a relatively high level, indicating that this area is generally valued by various manufacturers, while the roof area has the lowest score and needs to be paid attention to.

Fu Xiaofeng said that the CA-CAP evaluation exposed a total of 125 corrosion resistance problems of automotive products, among which the problems caused by the manufacturing process accounted for a relatively high proportion.
The industry needs to popularize and apply integrated die-casting, zinc-aluminum-magnesium alloy hot-dip plating, automatic flexible assembly and other processes to reduce the occurrence of corrosion problems in automotive products.

"CA-CAP is a breakthrough achievement in the field of automobile inspection and testing, which is beneficial to improve the corrosion resistance and aging performance of automobile products." Qiao Dong, the first-level inspector of the Department of Approval and Testing of the State Administration for Market Regulation, believes that the earlier "Passenger Car The release of the group standard "Corrosion Resistance Test and Evaluation Rules" has laid a good foundation for CA-CAP.
He suggested that CA-CAP should start from consumers' attention, establish an evaluation system combining subjective evaluation and objective testing, and use high-quality testing behaviors to promote the CA-CAP brand to gain wide recognition from the industry and consumers.
