Test, Validate, and Make a Waterproof Smartphone

We’ve been writing a lot about testing methods the past few weeks. What tests HZO performs, how we do them, the equipment we use, the results we get. While the fancy equipment and testing processes are pretty remarkable, it’s usually the results that blow people away.

A few weeks ago we talked about an HZO Protected waterproof e-reader that survived 92 IPX7 cycles. That’s 46 hours of submersion exposure. An amazing feat.

Just when you think it couldn’t get any better, our technical team does it again by developing a rigorous solution for a very popular aftermarket smartphone. The mission: Create an HZO Protected electronic device that people can swim with.

The testing equipment simulates swimming exposure by cycling the test product in and out of water repetitively. Here’s what we can tell you about the outcome:

HZO Protected Smartphone: Extended Exposure Swim Test

36 Days of Testing

24 Hour Cycles

864 Total Hours

313,200 Strokes

To put this in terms that are easier to understand, these testing totals are the equivalent of one hour of swimming, five days a week, for 3 and a half years. Jaw on the floor? Yeah. Safe to say that what we do here at HZO goes well beyond defined testing measurement.

If there is a future for waterproof electronics, then tests like this ought to be upping the standards that define how water resistant electronics can and should be tested and validated. IP testing has become the de facto measurement—mainly because there isn’t anything else for brands and electronics makers to use.

So let us remind you, faithful readers and observers, that an IP (ingress protection) test is a singular test, conducted on single product taken from a production run. That individual product only needs to pass the IP test parameters one time in order for the entire line of products to achieve the applicable IP rating certification. For the owner of an IP certified device (e.g. IPX7 or IP68), the certification means that a product should be able to survive a single exposure event. In the case of IPX7 that means 30 minutes of submersion in a meter of water—one time.

If truly water resistant and even waterproof electronics are the future, there has to be confidence that the technology protecting electronics will work consistently and to the performance standards that end users are starting to demand. This is where we point back to the results above as proof that HZO technology does what we say it does.

Mic Drop? Nah, we love this stuff, so we’ll keep pushing the boundaries of what’s possible and sharing the details as we go. Stay tuned.
