Now, with the progress of society, there are more and more electronic products on the market, and the detection of components is an essential basic work. After these electronic products are developed, how to accurately and effectively detect the relevant parameters of components must adopt different methods according to different components, so as to judge whether the components are normal or not. Only when the products are inspected and confirmed to meet the standards can they be launched. What are the inspection requirements and standards for electronic products? Let's have a look!

Electronic product inspection mainly includes the following standards. Let's have a look.

Common test basis of electronic products:Generally, common testing products are divided into four categories: 1 Household appliances shall be tested according to GB4706 standard; 2. AV audio and video shall be tested according to gb8898 standard; 3. It information technology shall be tested according to gb4943 standard; 4. LED lamps shall be tested according to GB7000 standard.

Inspection of electrical and electronic products: packaging inspection

1. Check whether the package is intact and free of damage, and whether there is 3C certification mark and certificate number on the color box (applicable to electronic products subject to national compulsory certification).

2. Check whether the number of accessories is correct. No misplacement, omission or mixing of accessories.

Inspection of electrical and electronic products: appearance inspection

1. Check that the product surface is free of scratch, pit, stain, stripe, damage, crack, deformation, color difference, burr and inequality.

2. Check the main parameters on the product identification, rated voltage, rated frequency, power type and symbol, rated input power, nominal pressure, etc.

Inspection of electrical and electronic products: structure and internal wiring inspection

1. Check the structural stability of the product to ensure that there is no assembly dislocation, and abnormal loosening or jamming is not allowed. Shake the whole machine for inspection, and there shall be no abnormal noise inside the machine.

2. Check that the internal wires, power lines, fuses, functional components and other components of the product must have national compulsory certification marks. And the internal wiring of the product shall comply with GB4706 19 standard provisions.

Inspection of electrical and electronic products: function inspection

Check the actual function of the product. Carry out relevant functional tests according to the product operation instructions. Relevant inspections shall be carried out in strict accordance with the operation steps in the operation manual.

Inspection of electrical and electronic products: anti electric shock protection inspection

1. When the product is installed and operated according to the normal use mode and in any use position, and after removing any easily removable parts, it shall have sufficient protection to prevent touching the live part of the switch. The handle, self-locking button and other accessible parts of the product shall be made of insulating materials.

2. Inspection method: conduct hi-pot test, or observe with naked eyes or touch every possible part with standard test finger.

Inspection of electrical and electronic products: durability test

The product is subject to pot test. After 4h, the product has no crash, int phenomenon, no excessive heating, and can work normally.

The inspection requirements of electronic products are mainly shown in the figure:

The above is the relevant knowledge about electronic product testing compiled by Xiaobian. Chuangxin testing always adheres to the purpose of "professionalism, efficiency and innovation", buys international advanced testing equipment with a large amount of money, and the testing strictly complies with international testing standards and methods. It has obtained CNAs certification and international mutual recognition qualification. Its customer base covers many countries and regions at home and abroad. It is of excellent domestic quality Well known professional IC testing organization. In the current market environment, quality inspection report is extremely important for products to settle in e-commerce and supermarket platforms, because quality inspection report is a very basic condition for products to settle in various platforms. We must pay attention to the selection of formal testing institutions, and then whether the test results have legal effect. The test results without public reliability obviously do not meet the standards, and waste time and energy.
