IP67 protection standard refers to the level of physical protection that a device or system has against external factors such as dust and water. Specifically, it means that the device is protected against the ingress of dust, and it is protected against the effects of being submerged in water to a depth of up to 1 meter for up to 30 minutes. This level of protection is commonly used for outdoor devices and equipment that may be exposed to dust and water in their operating environment and for applications that require full waterproofing. It is important to note that IP67 rated devices have high resistance to water, dust, and other particles and are suitable for many harsh environments.

Is IP67 fully waterproof?
Yes, IP67 rated devices are considered fully waterproof. They are able to withstand being submerged in water to a depth of up to 1 meter for up to 30 minutes without any water intrusion. This means that they can be completely submerged in water without any damage to the internal components.
It's also important to keep in mind that IP ratings only apply to specific conditions and test methods, so in order to make sure that the device will function properly in all conditions, it's a good idea to check the manufacturer's specifications or to test the device in similar conditions.

Is IP67 good enough to shower?
IP67 rated devices are considered fully waterproof and suitable for being submerged in water to a depth of up to 1 meter for up to 30 minutes. Therefore, it would generally be considered suitable for use in a shower, as long as it is not exposed to high-pressure water jets or steam. It's also important to check the manufacturer's specifications as they may have recommendations on how to use the device in such environments or any other specific restrictions.

It's also worth noting that even though IP67 rated devices are considered fully waterproof, they still may not be completely immune to water damage over time, especially if the seals or port covers are not properly maintained or if the device is exposed to high temperatures, chemicals, or other harsh environments.

IP67 vs IP68?
IP67 and IP68 are both international standards that measure the level of protection that a device or system has against external factors such as dust and water. Both ratings indicate that the device is protected against the ingress of dust and able to withstand being submerged in water.

The main difference between IP67 and IP68 is the depth and duration of the immersion test. IP67 rated devices are protected against the effects of being submerged in water to a depth of up to 1 meter for up to 30 minutes, while IP68 rated devices are protected against the effects of being submerged in water to a much greater depth and for a longer duration, typically for continuous immersion in water under pressure.

In general, devices with IP68 rating are considered to be more water resistant than IP67, as they can withstand deeper and longer immersion in water. If you need a device that can be submerged in water for an extended period of time, such as for use in a marine environment, you may want to choose an IP68 rated device. However, it's always recommended to check the manufacturer's specifications, as the conditions of the test can be different and thus affect the overall performance of the device in real-world scenarios.
