[Practical]What environmental endurance tests need to be done for automotive lighting accessories? Do you all know?
With the development of industry, technology is becoming more and more mature.Lamps as acarexternalAccessories, Is one of the important parts of the car. They are often affected by temperature changes and climate changes, such as extreme weather such as rain, sandstorms, and snow. Therefore, environmental testing is very important.
GB10485-89 "Basic Environmental Test for External Lighting and Signaling Devices of Automobiles and Trailers" also has relevant document regulations.Car lightsTen basic environmental tests are required: weather resistance test, temperature resistance test, vibration test, impact test, dustproof test, waterproof test, salt spray test, etc.; reflector aging test; strength and temperature change test. The most extensive air tightness tests are: high and low temperature damp heat test, high temperature test, rain test, sand dust test, salt spray test and vibration test.

Cars are complex products made up of thousands of electronic components. Especially with the development of the automobile industry, there are more and more control electronic components, entertainment multimedia electronic components, navigation and in-vehicle communications, making cars more complex. The reliability of these electronic components is very important, it directly determines the safety and operational reliability of the car. Especially harsh environments (transportation, storage, work, climate, etc.) are testing the reliability of automotive electronics. The editor of Ruikai here simply sorted out the environmental reliability test conditions of automotive electronic products to provide customers with references.
At present, there are many requirements and standards for environmental reliability testing of automotive electronic products in the world. Commonly used standards are ISO 16750 series, EIA-364 series, etc., see Table 1 below.
Table 1-List of common automotive electronic test standards:
Different test environmental conditions have different effects on the product and produce different failures. For example, under high temperature test conditions, the composition of the product will have the following effects: aging, vaporization, cracking, softening, melting, expansion and evaporation. Corresponding cars will have poor circuit system insulation, mechanical failures and mechanical failures. The pressure has increased. Under the low temperature test conditions, the following effects will be produced on the product components: brittleness, freezing, shrinkage and solidification, mechanical strength reduction, etc. Corresponding automobiles will have poor circuit system insulation and mechanical cracks. Failure, sealing failure, etc. Common environmental reliability test items are shown in Table 2 below.
Table 2-List of reliability tests related to automotive electronic products:
Because different parts of the car have different requirements for environmental reliability, such as: for temperature and environmental conditions, the upper part of the front dashboard of the car should be 120 C, the lower part should be 71 C, and the lower part should be 105 C, etc. Therefore, for the car due to electronic products The use and installation location of the spheroid are different, and the environmental reliability test conditions are also different. Table 3 below lists the main test items and test conditions for some common automotive electronic products.
