What IP rating is 100% waterproof

When it comes to electronics and electrical devices, one of the most important factors to consider is their level of waterproofing. In order to protect these devices from water damage, manufacturers often assign them an IP (Ingress Protection) rating. The higher the IP rating, the more resistant the device is to water and other foreign particles. In this article, we will explore what exactly an IP rating is and how it relates to the concept of being 100% waterproof.

Understanding IP ratings

An IP rating consists of two digits that represent the device's level of protection against solids and liquids. The first digit indicates the protection against solids such as dust and dirt, while the second digit represents the water resistance. For example, an IP67-rated device is completely protected against dust and can be submerged in water up to a meter for a prolonged period of time.

However, it is important to note that no IP rating guarantees 100% waterproofing. While a high IP rating indicates a high level of water resistance, it does not make the device completely impervious to water. Water-resistant devices are designed to withstand certain levels of water exposure, but they may still be affected by prolonged immersion or excessive water pressure.

The limitations of IP ratings

There are several factors that can affect the actual waterproofing capabilities of a device, regardless of its IP rating. Firstly, the age and condition of the device can impact its ability to resist water. Over time, seals and gaskets may degrade, compromising the device's waterproofing abilities. Additionally, the way the device is used and maintained also plays a role. If the device is not properly closed or if there are any gaps in its construction, water may still find its way into the device.

Furthermore, IP ratings are tested under controlled laboratory conditions, which may not accurately represent real-life scenarios. Factors such as water temperature, water pressure, and the duration of water exposure can all affect a device's ability to remain waterproof. Therefore, it is always important to exercise caution when using water-resistant devices, even if they have a high IP rating.


In conclusion, while an IP rating provides valuable information about a device's level of protection against solids and liquids, it does not guarantee 100% waterproofing. Water-resistant devices are designed to withstand certain levels of water exposure but may still be susceptible to damage under certain circumstances. It is important for users to carefully follow manufacturer guidelines and exercise caution when using these devices in or around water. Remember, no device is completely immune to water damage.
