All consumer electronic equipment shall have entrance protection level or IP protection level. Such as flashlight, mobile phone, wireless headset, Bluetooth speaker and other products. This is the standard and scientific method to judge the waterproof and weatherproof products. What is the meaning of IP protection grade? The next Yibo test explains the IP dustproof and waterproof grade and comparison table.

 

1、 The concept of IP

 

IP is the abbreviation of international protection, which means the internationally recognized protection level. IP protection level is generally composed of two numbers or supplementary letters: the first number indicates the level of preventing solid objects from entering, and the second number represents the level of waterproof entry. The larger the number, the higher the protection level. For example: ip68.6 means dustproof grade 6, 8 means waterproof grade 8.

 

The specific protection level numbers are as follows:

2、 IP grade indicator usage

 

IP grade is mainly used to assess the reliability of enclosure protection of all kinds of electrical products under various harsh environmental conditions such as dust, humidity, water drenching or diving, so as to verify whether the working performance of products and components will be damaged, and provide corresponding protection requirements for human body to prevent contact with dangerous parts.

 

1. There are six grades of dust-proof IP, which is an important index of safety protection. The standard of IP ×× recommended by International Electrotechnical Commission (IEC) is adopted. In the grade standard, the first ×× in IP ×× represents the protection level of dust, and 0-6 is used to indicate the dust protection level. Different dust-proof capacity will result in different grades. Please refer to the following instructions for details.

 

2. The waterproof IP grade has 8 protection grades, and the IP ×× standard recommended by the International Electrotechnical Commission (IEC) is adopted. In the grade standard, the second × in IP ×× indicates the protection level of liquid. Denoted by 0-8, IP × 0: no protection. Different waterproof capacity, grade is not the same, specific can refer to the following instructions to select.

4、 Precautions for dust and water proofing:

 

1. The customer shall confirm the product protection level or make a thorough test

 

2. Inform the size and weight of the test sample
