The International Standard IEC 60529 defines specific tests used to verify that an enclosure meets the requirements for ingress protection against particulates and liquids. However, when testing protective vents used in portable electronic devices, these tests can be broadly interpreted, resulting in inconsistent conclusions. W. L. Gore & Associates has developed additional protocols to test for IPx4 compliance that address these issues and mirror real-world conditions more effectively. With these protocols, we have improved the reliability of test results and the durability of the housings used in portable electronics.
Consumers believe water protection in their next smartphone is essential. Gore has confirmed this through a recent consumer survey regarding attitude and preferences toward smartphone water protection. Based on Gore’s survey results, this report will look into consumer expectations on water-protected smartphones and project their preferences for water resistance in three issues.
