What is the Full Form of IP Rating?

In the world of technology, especially in electronic products, you may have come across the term "IP rating" quite often. It's a commonly used term to describe the level of protection provided by an enclosure or device against the intrusion of foreign objects (solid particles) and liquids. IP rating, also known as Ingress Protection rating, consists of two digits that convey specific information about a product's resistance to different environmental conditions.

Understanding IP Ratings

The IP rating system was established by international standard IEC 60529 to provide a consistent way of determining and comparing the degree of protection provided by various electronic devices or enclosures. The first digit in an IP rating represents the level of protection against solid particles, such as dust, while the second digit indicates the level of protection against water or other liquids.

Solid Particle Protection (First Digit): This digit ranges from 0 to 6, with each number representing a different level of protection. For example, an IP rating of IP0X means there is no special protection provided against the entry of solid objects, while an IP6X rating signifies complete protection against the entry of dust or other particles.

Liquid Protection (Second Digit): The second digit ranges from 0 to 9, indicating the level of protection against different types of liquids. An IPX0 rating suggests that the device has no special protection against liquids, while an IPX9 rating implies protection against high-pressure and high-temperature water jets.

Examples of IP Ratings

Let's take a closer look at some common IP ratings:

IP65: A device with this rating is protected against dust (6) and low-pressure water jets (5). It is commonly found in outdoor lighting fixtures, CCTV cameras, or other electronic devices exposed to rain or damp environments.

IP68: Devices with this rating are fully dust-tight (6) and can be immersed in water beyond one meter for an extended period of time. You might find smartphones, smartwatches, or underwater cameras with this highly protective rating.

IPX7: This rating indicates that the device does not have a specific level of protection against solid particles but can withstand immersion in water up to one meter for 30 minutes. Some waterproof Bluetooth speakers or fitness trackers come with this rating.


In summary, IP rating is a standardized system used to determine the protection level provided by electronic devices or enclosures against solids and liquids. Understanding the different IP ratings can help you choose the right product suitable for your specific needs. So, next time you come across an electronic device with an IP rating, you'll have a better idea of what it signifies!
