How to apply for dust and water resistance test report - IP protection level test process
Application for shell IP dust and water resistance test report laboratory. All consumer electronic products should have an ingress protection level or IP protection level. Such as: flashlights, mobile phones, wireless headphones, Bluetooth speakers and other products. This is a standard and scientific method for judging whether a product is waterproof and windproof. What does IP protection level mean?

IP level indicator usage:

IP level is mainly used to evaluate the shells and seals of various electrical products. Humidity. The reliability of shell protection under harsh environmental conditions such as water sprinkling or diving to verify whether the working performance of products and components is damaged, and to bring corresponding protection requirements to the human body to avoid contact with dangerous parts.

1. Dustproof P level has 6 levels, which is an important indicator for selecting safety precautions by the International Electrotechnical Commission (EC) recommended IP×x level standard. In the level standard, IPxx has ×, indicating the dust protection level, and O- indicates each, with different dustproof capabilities and different levels. Please refer to the following instructions for selection;

2. Waterproof IP International Electrotechnical Commission has 8 protection levels (IEC) recommended IP×× level standard. In the grade standard, the second × in IP×× uses 0-8 to indicate the liquid protection level, IP×0: no protection. Different waterproof capabilities and different levels can be selected by referring to the following instructions.

IP protection level certification qualification criteria:

1. Dustproof test: The corresponding test tools of IP1X~IP4X cannot pass through the opening. The IP5X and IP6X dustproof tests need to determine whether there is dust deposition inside the shell. The IP5X dustproof test is slightly looser (depending on the amount and location of dust deposition to determine whether it affects safety or operation). For the IP6X dustproof test, it is dust-tight (negative pressure needs to be drawn during the test), and dust is not allowed to enter. Therefore, if dust enters the shell, it is judged as failing the test.

2. Waterproof test: IPX1-IPX8 waterproof tests all need to determine whether there is water droplets entering the shell. Generally speaking, if water enters, it should not be enough to affect the normal operation or safety of the equipment; water cannot accumulate on insulating parts that may cause leakage tracking along the creepage distance; water cannot enter live parts, or enter windings that are not allowed to operate in a wet state; water does not accumulate near cable heads or enter cables.

Concept of IP:

IP ​​is the abbreviation for INTERNATIONALPROTECTION, which refers to the internationally recognized protection level. The IP protection level is generally composed of two numbers or supplementary letters: the first number indicates the level of solid entry, and the second number indicates the level of waterproof entry. The larger the number, the greater the protection level. For example: IP68.6 means dustproof level 6, and 8 means waterproof level 8.

IP level application process

1. Project application-submit IP certification application.

2. Data preparation-according to the IP certification requirements, the company prepares relevant certification documents.

3. Product testing-the company sends the samples to be tested to the laboratory for testing.

4. Prepare report - the certification engineer prepares the report based on the qualified test data.

5. Submit for review - the engineer reviews the complete report.

6. Issue certificate - after the report is reviewed and found to be correct, the IP certification certificate is issued.
