IP68

IP68 is the second-highest immersion rating in IEC 60529. The first digit, 6, certifies a fully dust-tight enclosure. The second digit, 8, confirms protection against continuous immersion beyond one metre, with the exact depth and duration defined by the manufacturer. IP68-rated rugged devices are sealed for prolonged underwater exposure, well beyond the temporary immersion covered by IP67.This rating is specified for rugged smartphones, sealed sensor and electronics enclosures, and antimicrobial industrial keyboards used in flooded, submerged, or heavily contaminated environments. Because the depth and time are set by the manufacturer rather than fixed by the standard, always check the published IP68 test parameters against your real conditions. For hot high-pressure sanitary washdown, IP69K is the appropriate rating.Frequently asked questionsWhat does IP68 mean?IP68 is the second-highest immersion rating in IEC 60529. The first digit, 6, certifies a fully dust-tight enclosure. The second digit, 8, confirms protection against continuous immersion beyond one metre, with the exact depth and duration defined by the manufacturer. IP68 devices are sealed for prolonged underwater exposure, well beyond the temporary immersion covered by IP67.Is IP68 fully waterproof?IP68 is the highest standard immersion rating and seals a device for continuous underwater exposure, but it is not unlimited. Because the depth and time are defined by the manufacturer rather than fixed by IEC 60529, always check the published IP68 test parameters against your real conditions. For hot, high-pressure sanitary washdown, IP69K is the appropriate rating instead.What is the difference between IP68 and IP69K?IP68 certifies continuous immersion beyond one metre, to a depth and duration set by the manufacturer. IP69K, defined by ISO 20653, certifies protection against close-range, high-pressure, high-temperature water jets used in steam and sanitary washdown cleaning. Choose IP68 for deep or prolonged immersion; choose IP69K where aggressive hot-water washdown hygiene regimes apply.
