The standards that GST is involved in drafting will be implemented on 29 May 2020
On May 29, 2020, GST participated in the drafting of CSAE 133-2020 "light aging technology requirements for passenger vehicle parts laboratory" standard, which was officially implemented today.
Car is aging, many car companies with the product life cycle, investment funds, in the field of the most human and auto aging technology has been neglected, auto enterprises in our country mainly by reference to European and American automakers aging standard is given priority to, neither formed the perfect standard system, also does not have to combine the existing automobile industry chain, and a large amount of data related to the aging serious lack, the domestic automakers Zeng Pin now appears to be a massive market complaints because of ageing problems.
Automobile products are exposed to the external complex environment for a long time, which often affects the appearance and performance of automobiles due to aging and corrosion.With the continuous improvement of domestic consumers' requirements for the quality of automobile products, the anti-aging performance of automobiles has had an important impact on the economic benefits and brand awareness of enterprises, and more and more automobile enterprises begin to pay attention to the aging problem of automobiles.
CSAE 133-2020 standard specifies the technical requirements for the laboratory light aging performance of passenger vehicle parts.The main test conditions are as follows:

Under the test conditions of the blackboard temperature of 89 ℃±3 ℃, the air temperature of the box body of 62 ℃±2 ℃ and the relative humidity of 50%±5%, the light cycle was run for 3.8h. Under the test conditions of the blackboard temperature of 38 ℃±3 ℃, the air temperature of the box body of 38 ℃±3 ℃ and the relative humidity of 95%±5%, the dark cycle was run for 1 h. |

Under the test conditions of the blackboard temperature of 38 ° c ±3 ° c, the air temperature of the box body of 38 ° c ±3 ° c and the relative humidity of 95%±5%, the dark cycle was run for 60 min, and the front and back sides were sprayed at the same time. Under the test conditions of the blackboard temperature of 70 ℃±3 ℃, the air temperature of the box body of 47 ℃±3 ℃ and the relative humidity of 50%±5%, the light cycle was run for 40 min. Under the experimental conditions of the blackboard temperature of 70 ° c ±3 ° c, the air temperature of the box body of 47 ° c ±3 ° c and the relative humidity of 50%±5%, the light cycle was run for 20 min, and the front side was sprayed at the same time. Under the test conditions of the blackboard temperature of 70 ℃±3 ℃, the air temperature of the box body of 47 ℃±3 ℃ and the relative humidity of 50%±5%, the light cycle was run for 60 min. |
