waterproof /ˈwɔːtəpruːf/ adjective impervious to water
The IPX Scale
Some brands have tried to invent their own definitions of waterproofing. But actually an international standard already exists – so at Aquapac we use that.
The international standard is called IEC 60529 – Degrees of Protection Provided by Enclosures and it was developed by a technical committee of the International Electrotechnical Commission. In the USA it has been adopted by the National Electrical Manufacturers Association (NEMA) as an American National Standard.
The whole thing is dozens of pages long, this is a summary:
|IP Code:||Protected against:||at Aquapac we call this:|
|Vertically falling water drops||Rainproof|
|Vertically falling water drops – enclosure tilted up to 15º from normal position||Rainproof|
|Water falling as a spray falling at any angle up to 60º from vertical||Sprayproof|
|Water splashing from any direction||Splashproof|
|Water jets – water projected at all angles through a 6.3mm nozzle||Stormproof|
|Powerful water jets – water projected at all angles through a 12.5mm nozzle||Stormproof|
|Protected against immersion for 30 minutes to a depth of less than 3ft/1m||Submersible|
|Protected against continuous immersion to a depth of 30ft/10m (see Independent Testing below).||Submersible|
When we patented the Aquaclip® sealing system it was submitted for independent testing. IPX8 testing was for 30 minutes at the equivalent of a depth of 30ft/10m.
Some of the Aquaclips proved waterproof at very much greater depths. Our Keymaster™ case for example is 100% waterproof to 165ft/50m.
During manufacture we batch-test the IPX8 Submersible cases in our pressure chamber.
We also subject them to a simple manual squeeze-in-a-basin test (sometimes it’s the real-life tests that really count!)
