What does IP67 mean

In recent years, smart phones have become an essential tool for every one of us in daily life. Actually, smart phone is not only a communication tool, but also a digital camera, a game machine, an electronic mailbox, or even a wallet. With more and more digital electronic products to support the function of waterproof and dust-proof, we can often hear the terms about it, such as IP54, IP67 and so on. Although the expression of figures is very simple, it is not easy for people to understand at first glance. Therefore, in this article, we take the IP67 for instance to discuss the meaning of this standard.

What does IP67 mean?
IP67 refers to the protection level of the mobile phone industry. IP is the abbreviation of “Ingress Protection Rating”, which defines the proof capability of an interface against liquid and solid particles. IP is followed by 2 digits. The first one refers to the level of protection against solid particles, which ranges from 0 to 6, indicates the capability of proof against from large particles to dust respectively. As follows:

0: No protection;
1: Protection against particles whose diameter is 50mm or greater in size;
2: Protection against particles whose diameter is 12.5mm or greater in size;
3: Protection against particles whose diameter is 2.5mm or greater in size;
4: Protection against particles whose diameter is 1mm or greater in size;
5: Protection against parts of dust, but not completely. However, the dust entering into electronic products will not interfere with the normal operation of the equipment.
6: protection against all dusts.

The second one refers to the level of protection against liquid, which ranges from 0 to 8, indicates the capability of proof against from vertical water-drop to water pressure under water. As follows:

0: No protection;
1: Protection against the vertical falling water droplets;
2: Protection against the falling water droplets when the shell of electronic products is tilted to 15 degrees;
3: Protection against water mist spraying at an angle no more than 60 degrees;
4: Protection against water-sprinkling at any angles;
5: Protection against water spraying at any angles;
6: Protection against powerful water spraying at any angles;
7: Protection against immersion in water for a short time;
8: Protection against immersion in water for a long time.

From here we can summarize that, the larger the digits are, the stronger the capability of protection is. And IP67 means that the electronic product protects against all dusts and immersion in water for a short time. At present, IP67 is the highest level that is achievable in common mobile phone industry.

However, even if your mobile phone, camera or other electronic products have the function of water or dust resistance, you should still take good care of it. If you don’t want to meet a series of problems, you’d better not take it to swim or bath, even it reached the level of IP67.
