Why do cellphone waterproof ratings have a time limit? Example 6 meters for 30 minutes.
In: 54
That depends on what IP rating a device have. Which they are tested against. If they are not tested against it: claim can’t be made that it’s rated for that.
A phone got ports etc, which is hard to make it fully IP rated. Most “waterproof phones are IPX7, that’s “temporary immersion”. Some phones are IPX8 now that’s “continuous immersion”.
Edit: they put a time to define just what “temporary” means, as some will OF COURSE challenge that.
