The firecrackers are too loud, which makes the mobile phone fall into the water, relying on IP68 technology

It's Spring Festival. The firecrackers are too loud. I'm scared mobile phone If you fall into the water, the survival rule in the world is "survival of the fittest", as is the case with digital products, and mobile phones with dust-proof and waterproof functions will survive. We have to admit that the dust-proof and waterproof function of IP68 has become the mainstream function of the contemporary flagship machine. So what are the differences between the dust-proof and waterproof measures of major manufacturers? Let's take a look.

First, let's understand The concept of IPXX protection grade.

Many people who know the three prevention mobile phones should know the concept of IP grade, but the waterproof degree of each grade is not very clear, or the three prevention mobile phones do not know what the three prevention functions are. In fact, the definition of "three prevention" mobile phones is very simple. They are slightly dust-proof, shockproof and waterproof, without the so-called explosion-proof, lightning protection and other gimmicks.

The "IP" here is the international protection standard grade; In short, the two digits "XX" in IPXX represent the dustproof and waterproof grades respectively, of which the dustproof grade is from 0 to 6 and the waterproof grade is from 0 to 8.

The first "X" refers to the level of preventing foreign objects and dust from entering, and its protection ability is judged by the scale numbers of 0-6:

For mobile phone devices, dust-proof level 5 means that the device has a good dust-proof effect. Although it cannot completely prevent dust intrusion, the amount of dust intrusion will not affect the normal operation of electrical appliances; Level 6 is to completely prevent dust intrusion, all interfaces and other parts are completely sealed, and completely isolated from internal components.

The second "X" refers to the waterproof grade, which is a unified standard formulated by the international industrial waterproof grade standard IPX and the JIS grade of the Japanese industrial waterproof standard. The waterproof capacity is divided into 9 grades by 0-8 standard numbers:

In brief, for some mobile phones with ordinary waterproof performance, as long as the anti splash ability of level 6 and below is achieved, it can prevent some domestic sprinkler and rainwater from invading into the mobile phone. Level 7 means that the equipment can withstand immersion for up to 30 minutes in water within 1 meter without water entering the interior. Level 8 standard goes further, It can ensure that the equipment is safe within 30 minutes after immersion in water below 1.5 meters.
