Why the mobile phone alleges " waterproof " , but doesn't the finish that drink water guarantee?

IPhone is had " IP67, IP68 " waterproof and dustproof grade, although official asymmetry " waterproof " , however " prevent splash fight water " , but if the mobile phone drinks water really, the government won't guarantee.

This makes many young companionate generation interrogative, why to have defend of grade " waterproof " cannot the mobile phone guarantee into water finish?

Actually, the great majority that includes an apple inside " waterproof " mobile phone manufacturer does not support guarantee into water, xiaole explains a reason simply for everybody below.

What is " IP67, IP** " defend grade?

In the mobile phone on market or electronic product, a lot of tag oneself product to support grade of IP67, IP68, IP** defend level, what meaning is this?

Actually very good understanding, the first number after IP represents waterproof social estate on behalf of the 2nd dustproof grade, number, detailed meaning pursues as follows:

With IPhone XS " IP68 " grade is exemple, its are OK " completely dustproof, immerse continuously in the depth of water in more than one meter " , and of IPhone X " IP67 " can " completely dustproof, immerse 30 minutes are in in a meter depth of water " . This immerses bothly time is different.

This is another common error, can see from inside the watch actually, the meaning that each number represents is different, some are gush water, some are to immerse.

Because this can not say IP68 to compare IP66 to be close friends certainly, because the mobile phone of IP68 or license are with immersing for long in water, but likelihood water column one gush with respect to breakdown.

※ has IP65 and IP68 at the same time the waterproof mobile phone of two grade

Also because such, some hands opportunity tags a variety of waterproof grade at the same time, for example Sony Xperia XZ achieved IP65 and IP68 two grade, state it can bear low-pressure water column, also can immerse continuously in water, this is both it is different.

In the standard test of IP** " test water " be " clear water " , that is to say, have caustic acerbity water, seawater, swimming-pool water, it is bleb water even not be in test standard.

Accordingly, make clear on even if mobile phone tagging IP68 waterproof grade, but this can not take it to be used in swimming-pool, seawater on behalf of you.

The most waterproof mobile telephone that includes IPhone inside is it is to use balata will jam all aperture on airframe, but brine or other caustic water may damage balata, sealing nature can be reduced gradually.

Corrode besides the liquid, use the sealing that reduces balata possibly also daily, the addition as use time, fall fall, the circumstance such as insolate may cause balata ageing, affect waterproof properties then.

The sealed balata in ※ IPhone 6s,

Dan Ping did not publicize the waterproof properties of IPhone 6s if really.

Because the manufacturer can be judged only " whether to drink water " , cannot judge " the what water that drink " , " the water that how drinks " .

Most manufacturer can be passed only simple " immerge indicator (LCI) " will judge airframe to whether drink water, cannot be informed is immerse in underwater into water, still be entered by eject of high-pressured water column water, whether to contact caustic liquid to wait a moment.

The manufacturer cannot judge the environment that drinks water, also won't offer naturally guaranteed into water. And the addition as use time, whether does the mobile phone often insolate, often fall fall, the ageing circumstance of sealed balata also cannot be judged, this also is one of reasons that do not guarantee into water.

So, " waterproof " the function can be only " passivity defends " function, cannot use at will in underwater, cannot contact mordant water more.

Hope young associate understood a mobile phone the little knowledge of waterproof backside, do not feel to defend jack-tar plane " 100 poison are not invaded " , still should cherish use!

Finally, xiaole reminds young associate even people oh, take the mobile phone the shower room improper also oh, the mobile phone is waterproof but might as well water mist oh, after water mist enters a mobile phone, may corrode advocate board spare parts, the likelihood is used to what did not come leave snake in the grass.
