White Paper: Improved Consistency in Testing

Improved Consistency in Testing for Water and Particulate Protection

Cherish K. Wilford, Application Engineer

Electronic devices with audio components must include openings in their housings to enable sound waves to be transmitted. Having a durably rugged housing for your portable electronic device protects the internal electronics from environmental contaminants. The International Standard IEC 60529 defines specific levels of protection for enclosures with electronic voltage not exceeding 72.5 kilovolts. The requirements outlined in the IEC 60529 standard do not adequately provide consistent testing of the protective vents needed for portable electronic devices. W. L. Gore & Associates has developed four testing protocols that address these issues and mirror real-world conditions more effectively. With these protocols, we can improve the reliability of test results and the durability of the housings used in portable electronics.
