IP68

IP68 is a rating in the IP (Ingress Protection) code defined by the International Electrotechnical Commission (IEC). The code consists of two digits. The first digit, 6, indicates that the device is dust-tight, providing full protection against solid objects. The second digit, 8, indicates protection against immersion in water beyond 1 meter. The exact immersion depth and duration are not standardized by the IP code itself and are specified by the manufacturer for each device. In practice, products with IP68 ratings are often tested to withstand immersion in water deeper than 1 meter for an extended period, with common specifications ranging from about 1.5 to 3 meters for 30 minutes to 1 hour, though there is no universal depth or time.

The rating is determined through standardized laboratory tests: a dust ingress test to verify dust-tightness, and a water immersion test conducted under conditions defined by the manufacturer. IP68 does not imply the device is waterproof in all situations; it does not guarantee protection against high-pressure jets, saltwater, chemicals, or long-term exposure. It also does not address other forms of damage such as impacts, temperature extremes, or wear over time, nor does it cover devices with removable parts.

IP68 ratings are commonly seen on smartphones, wearables, cameras, and other portable electronics that benefit from dust protection and immersion resistance. For consumers, it is important to consult the manufacturer’s documentation for the precise depth, duration, and any environmental caveats related to the rating.
