Since September 2015, the new NESHAP (National Emission Standards for Hazardous Air Pollutants) regulations are in place. Many of the cement plants in the United States face the burden of proving their compliance with these new standards.

The International Standard IEC 60529 defines specific tests used to verify that an enclosure meets the requirements for ingress protection against particulates and liquids. W. L. Gore & Associates has developed additional protocols to test for IPx4 compliance that address these issues and mirror real-world conditions more effectively.

The challenge of designing electronic devices that stay protected from dust, liquids and pressure becomes increasingly difficult when acoustics are introduced.

Selecting the right acoustic vent for an electronic device requires a balance between the level of protection the vent supplies, and what the vent contributes to the overall sound performance of the acoustic system.

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.
