Oscillating tube: Test duration: 10 minutes, or spray nozzle (same as IPX3 spray nozzle with the shield removed) b) is conducted (without shield) for 5 minutes minimum. Water splashing against the enclosure from any direction shall have no harmful effect, utilizing either:a) an oscillating fixture, or b) A spray nozzle with no shield. Test b) is conducted (with a shield in place) for 5 minutes minimum.įor a spray nozzle: Test duration: 1 minute per square meter for at least 5 minutes Water volume: 10 liters per minute (0.037 impgal/s) Pressure: 50–150 kPa (7.3–21.8 psi)For an oscillating tube: Test duration: 10 minutes Water volume: 0.07 liters per minute (0.00026 impgal/s) per hole Test a) is conducted for 5 minutes, then repeated with the specimen rotated horizontally by 90° for the second 5-minute test. Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect, utilizing either: a) an oscillating fixture or b) A spray nozzle with a counterbalanced shield. Water equivalent to 3 mm (0.12 in) rainfall per minute Test duration: 2.5 minutes for every direction of tilt (10 minutes total) A total of four positions are tested within two axes.
Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle of 15° from its normal position. Test duration: 10 minutes water equivalent to 1 mm (0.039 in) rainfall per minute X means there is no data available to specify a protection rating with regard to these criteria.ĭripping water (vertically falling drops) shall have no unsafe effect on the specimen when mounted in an upright position onto a turntable and rotated at 1 RPM. However, most smart watches on the market have an IP68 rating, which is still very good. There are actually different levels of IP68 protection, with the highest level being IP68K. But for a smartwatch, it is especially important since the watch will likely be worn during activities where it could be exposed to water, such as swimming, sweating during a workout, or being caught in the rain. Water-resistance is always an important factor to consider when purchasing any type of electronic device. The first number, “IP” stands for “ingress protection” while the second number, “68”, corresponds to the specific level of protection. IP68 is a rating system developed by the International Electrotechnical Commission (IEC) to classify the degree of protection against solid objects and water. But what does that mean? And is it important? In this blog post, we will explain IP68 water resistance and why it matters when choosing a smartwatch. If you are in the market for a new smartwatch, you have likely come across some watches with an IP68 water resistance rating.
