The iPhone is finally waterproof!
In the iPhone 7 announced today, the iPhone has finally become a waterproof / dustproof structure.The waterproof / dustproof performance of iPhone 7 seems to be "IP67".What level is the IP67 achieving waterproof / dustproof? I looked it up.
How powerful is the IP67?
IP is the protection grade specified by the International Electric Standards Meeting (IEC).After the IP, the grade of the human body and the solid indicates the grade of the water entry.In other words, IP67 means that it has a sixth grade dustproof performance and a 7 -grade waterproof performance.
How much waterproof / dustproof performance is specifically?Let's refer to the Nippon New Industry page, which is headquartered in Ishikawa Prefecture, which develops / sells industrial measuring instruments.

The dustproof performance of the 6th grade is the highest level, and it is said that dust does not enter the inside.The waterproof performance of the seventh grade is one step lower than the highest level 8, and it is said that "the prescribed pressure, soaking in the water in water is not harmful."
For this reason, the IP67 protection grade is quite high in both waterproof and dustproof."Even if you soak in the water, it will not be harmful to be harmful," so it seems fine to spill rain or cup of water.
However, since the official website states that "damage caused by water is not eligible for warranty", it may be safer to avoid wet aggressively.
As an aside, I used to use a smartphone that sang waterproof / dustproof (manufacturers and models are hidden here).At one point, I thought, "Let's endure it properly!", And when I sank it in the water, I felt sick from the next day, started to make a strange movement from the next day, and finally stopped turning on.Because I was there, I wouldn't be unreasonable if I bought an iPhone 7.
