How to handle the UL867 test report of the air purifier ?

With the development of the Amazon platform, there are more and more products, and the platform's quality control of products will become more and more strict. Recently, many Amazon business opportunities are asking for UL certification reports. We have done a lot of UL certification reports. Customers submit our reports to Amazon in the United States and all of them have passed. They asked us to do UL reports, with thoughtful service and speed.

So for car charger products, the standard proposed by Amazon is UL2089, so how to apply for the car charger UL2089 report?

Mobile power tool application UL reporting process:

1. Fill in the application form for testing and certification

2. Submit product information (2-3 samples, CDF list, instruction manual, nameplate, etc.)

3. The testing laboratory receives the sample and conducts the test

4. The test is qualified, and the testing laboratory issues a UL report

Test items required for fixed lamps:

1. Input test (nominal limit +/-10)

2. Temperature rise test

3. Withstand voltage test (Class I 2U+1000, Class II 2500V)

4. Ground continuity test (the resistance value should not exceed 0.5 ohms)

5. Lifting weight test (4 times gravity, measuring 1H)

6. Rain test (4H without water, single item test/model)

7. Tide test (93% humidity, temperature 25, 168H)

8. Exception testing

9. Stress of plastic (specific temperature TE=TI+10)

10. Shock test

Pay particular attention to areas where the fixed lamp test is prone to failure:

1. Enter the test.

2. Temperature rise test (especially the driven TC is easy to get warm)

3. Impact test

4. Rain test (very important, but also particularly prone to failure)

The bulb lamp is UL certified, and the place where the safety test is easy to fail pay special attention to the place where it is easy to fail:

1. Lamp gauge test. (That is, the weight of various lamp holders cannot be standardized)

2. Enter the test.

3. Temperature rise test (fuse 100 degrees, point solution capacitor 105 degrees, varistor 85 degrees)

4. Mechanical strength test of lamp head (one torque, one tension)
