 „Underwaterproof“ is an in-company test standard by InduKey. This standard exceeds the protection level IP68, which until now has been the highest standard for keyboards. Protection level IP68 means that the products are tested for water tightness by temporarily immersing them into water. The devices which are labelled “underwaterproof”, however, have been tested under water for at least 24 hours. In the process, the water column amounts to at least one meter.
Another difference arises during the active testing of the device. In contrast to IP68, where the devices are only passively immersed into water, the testing according to the “underwaterproof” standard involves an active operation of the keys in particular time intervals. In addition, upon completion of this test, a final and comprehensive testing of the keyboards is conducted.
Products which comply with the „underwaterproof“ standard guarantee the user a high resistivity in wet to humid environments and demonstrate durable, robust quality and functionality.
