IP Ratings Chart – Ingress Protection Ratings
IP Ratings Chart: The inside guide
An IP rating is designed to let you know how susceptible a product is to the ingress of water or solid particles like dust or sand. IP stands for ingress protection and testing is essential if you want to know how water-resistant or sealed your products are. It is industry standard for testing everything from plug sockets to high-tech consumer electronics like fitness watches or phones.
Understanding ingress protection ratings
There are a series of different IP ratings to show you the different levels of resistance to ingress a product might have. The rating is divided into separate letters or numbers, each digit telling you a different thing about the product’s resistances.
- Each rating starts with IP, to show it’s an ingress protection rating.
- It’s then followed by a digit letting you know the level of protection against solid ingress.
- Next is a digit to show you how protected the product is against the ingress of water.
IP ratings chart
|Protection from SOLIDS||Protection from WATER|
|0/X||No protection||0/X||No protection|
|1||Protected against solid objects bigger than 50mm, like a hand.||1||Protected against vertical water drops.|
|2||Protected against solid objects bigger than 12.5mm, like a finger.||2||Protected from water drops that land at a 15 degree angle.|
|3||Protected against solid objects bigger than 2.5mm, like a screwdriver||3||Protected against water sprays of a 60 degree angle.|
|4||Protected against solid objects bigger than 1.0mm, like a needle||4||Protected against water spraying from any angle.|
|5||Dust protected, offering enough protection to avoid serious harm by dust||5||Protected against water jets from any angle.|
|6||Dust tight, completely protected from the ingress of dust||6||Protected against powerful water jets and heavy seas.|
|7||Protected against immersion in water of between 150mm and 1 meter for up to 30 minutes.|
|8||Protected against submersion in water for long periods, exact depth dependent of manufacturer’s specification.|
|9||Protected against high pressure and temperature water, such as concentrated jets.|
To understand the rating, you look up the first digit in the column on the left and then the column on the right. For example, an IP67 rating will let you know that the components in an electronic product or device meets the standard ingress protection (IP) rating for consumer products, meaning they are dust tight and protected against immersion in water for up to 1 meter for up to 30 minutes.
