The power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of a casing, a power transformer and a rectifier circuit. According to its output type, it can be divided into AC output type and DC output type; according to the connection method, it can be divided into wall plug and desktop. Since mobile PCs do not have batteries, power adapters are particularly important. However, in general, if such products want to be listed on domestic e-commerce platforms, they need to apply for a quality inspection report.

What is a quality inspection report?

The so-called quality inspection report refers to the safety and performance inspection of the product, which has successfully entered other platforms such as Tmall, Jingdong Mall or supermarkets, or is a reference standard for consumers. According to the three-level standard (national standard, ministerial standard and enterprise's own standard), carry out quality assessment, make basic evaluation, and analyze the reasons for qualified or unqualified quality. This is the main body of the QA report. Only a laboratory authorized by China Metrology Certification (CMA) + China National Accreditation Service for Conformity Assessment (CNAS) is required, and the quality inspection report issued is valid.

What are the common uses of quality inspection reports?

◆ Settled in online malls such as JD.com and Tmall;

◆ Bidding/bidding;

◆ Report for project acceptance;

◆ Supplier requirements;

◆ Publicity reports;

◆ Settled in 4S stores (general auto supplies);

◆ Reports required for TV shopping;

◆ Reports required by stores (such as Wal-Mart, Carrefour, Rainbow, Guoanju, B&Q, etc.).

Note: If the electronic and electrical products are stationed in Jingdong and Tmall, you need to confirm whether the product needs 3C certification. If it is not within the scope of 3C, the test report is only useful. If it is within the scope of 3C, you need to provide 3C certification first.

Quality inspection report test standards and items

1. Safety regulations:

Signs and instructions, protection against touching live parts, input power and current, heat generation, leakage current and electrical strength at operating temperature, resistance to humidity, leakage current and electrical strength, abnormal operation, mechanical strength, construction, heat resistance and Fire resistance, etc.

2. EMC test items:

148.5KHz-30MHz terminal strong disturbance voltage, strong disturbance power, strong radiation disturbance, intermittent disturbance, electrostatic discharge, electrical fast transient burst, injection current, radio frequency electromagnetic field, surge (impulse), voltage sag and short-term interruption Wait.

Adapter quality inspection report processing process

1. Provide product-related information and fill in the application form

2. Mail samples for testing

3. Receive the sample and test the items corresponding to the standard

4. After the test is completed, a draft product test report will be issued

5. Check that it is correct, and issue the original test report.

To cover the report with the CMA and CNAS chapters, samples must be required, and the actual measurement can be produced.
