What are the reliability testing standards for wireless phone chargers?

(1) the scope of the reliability test standards for cell phone wireless chargers:

This standard specifies the reliability performance requirements that cell phone chargers need to meet, as well as their test methods and quality assessment criteria.

This standard applies to the company in the development of new products and production and shipping process of the charger sample confirmation, periodic quality control, shipping reliability testing standards.

1.1 The number of test items for each experimental project: 5PCS

1.2. The test item should be inspected and function tested before the project, and the experiment should be conducted only after the inspection is passed.

The inspection results should be recorded in the reliability test record sheet.
