The International Electrotechnical Commission (IEC) has specified the IPX7 and IPX8 waterproof tests in order to assess the degree of protection given against water intrusion in electronic and electrical goods. These tests may be found on the International Electrotechnical Commission website. The IPX7 waterproof test determines whether or not a product can remain functional after being submerged in water at depths of up to one meter for a period of at least half an hour. The purpose of the IPX7 test is to confirm that the product is waterproof, and that water does not enter the inside of the device. This may be accomplished by ensuring that water does not permeate the device. The IPX8 waterproof test determines whether or not a product can continue functioning normally after being submerged in water for a lengthy period of time, which is often several hours. The length of time and depth of immersion necessary to pass the IPX8 test are both specified by the manufacturer; neverthele...
