If you have ever purchased tools, equipment, or electronics, you may have noticed the item has an IP rating. If you have questions regarding this rating, you are not alone. To help you better understand IP ratings, we have created this guide.

What does an IP rating mean?
An IP rating, also known as an Ingress Protection rating or International Protection rating, refers to the level of protection against solids, liquids, moisture, and accidental contact offered by electrical equipment with a voltage rating not exceeding 72.5 kV.
What do the Digits in an IP Rating mean?
An IP Rating consists of the letters IP followed by two numbers. The higher the number, the better the protection. Sometimes, the numbers are replaced with an X, meaning the enclosure is not rated for the specification.
Using the IP67 rating as an example, let us explain what it means.
IP67 – First Digit = Solids
The first digit signifies the protection level against solids, such as tools, dirt, dust, or even fingers, which could damage the electrical conductors or movie parts if they were to come in contact. These numbers range from zero, meaning no protection against foreign objects, to six, dust-tight.
IP67 – Second Digit = Liquids
The second digit indicates the level of protection against various forms of moisture, such as drips, sprays, and submersions. There are specific angles, pressure, and volume requirements when testing products. The liquid protection ranges from zero, no liquid protection, to 9(K), protection against high-temperature, high-pressure water jets. Occasionally, an additional letter behind the numbers provides supplemental information regarding the product standard. Below are the most used supplementary letters:
- D – Wire
- F – Oil-resistant
- H – High voltage device
- M – Device moving during water test
- W – Weather conditions
What is an IPX rating?
IP ratings containing “X” denote that there is no available data. For example, IPX4 means the product has either not been tested to see its solid protection level or the data was inconclusive but protects against splashing water. Sometimes, you will see “X” be replaced with a zero, as no protection rating has been given.
What is an IPK rating?
An IP rating of “K” indicates protection against water damage from direct water jets of elevated temperatures and pressure. Examples of an IPK rating would be wash-down environments such as steam cleaning procedures, car washes, and food and beverage applications.
Other Frequently Asked Questions
Ip ratings of IP65, IP66, and IP67 are considered waterproof.
The International Electrotechnical Commission (IEC) classifies and provides guidelines determining protection against intrusion, dust, accidental contact, and water.
IP69K provides total protection against dust and direct water jets. IP69K is the highest level IP rating.
