IPX Ratings Chart | Waterproof Fully Explained

What do IPX Ratings Mean?

To get a full grasp of IPX waterproof ratings it is not just the number at the end that is important to know.

Waterproof ratings are dictated by an international code published by the International Electrotechnical Commission (IEC).

The code that spells out the standard for waterproof ratings is the IEC 60529 IP CODE.  IP stands for Ingress Protection.

Ingress simply means a going in or entering.  There for IP references the level of protection needed to prevent entering.

Now that we have the first two letters translated in an IPX rating, let’s discuss the third.

The X in IPX stands for protection from solids.  Since we are concerned with waterproof ratings, the X is a placeholder for solids and when unknown or unneeded the letter X is used.

Now that you have a full understanding what IPX references, lets go through the IPX Ratings Chart itself.

We will discuss what level of protection each numeric level provides and how it was tested.

IPX1 Rating

(Dripping Water)

Products in the IPX1 Waterproof protection category should be able to withstand vertically dripping water without harmful effect.

Protection at this level was tested for a period of 10 minutes under vertically dripping water equivalent to 1mm of water volume and was found to have no ingress of water.

Product Example: Electric Automatic Hand Dryer

IPX2 Rating

(Dripping Water at an angle)

Products in the IPX2 Waterproof protection category should be able to withstand vertically dripping water when tilted to 15° of its normal position without harmful effect.

Protection at this level was tested for a period of 10 minutes under vertically dripping water equivalent to 3mm of water volume and the protective enclosure was tilted at 15°.

Product Example: USB Rechargeable LED Bike Tail Light

IPX3 Rating

(Spraying Water)

Products in the IPX3 Waterproof Rating protection category should be able to withstand vertically falling water in the form of a spray out to a 60° angle from vertical without harmful effect.

Protection at this level was tested for a period of 10 minutes at a volume of about 1.84 gallons per minute at a pressure between 11.6 psi to 14.5 psi.

Product example: Solar Hand Crank Emergency Weather Radio

IPX6-K Rating

(Increasing Pressure of Powerful Water Jets)

Products in the IPX6-K Waterproof Rating, a rarely used sub category of protection, should be able to withstand water from about a one quarter inch nozzle against the protective layer.

Protection at this level was tested for a period of 3 minutes at a volume of about 19 gallons per minute at a pressure of 145 psi from a distance of 9.84ft.

IPX7 Rating

(Immersion of up to 3 ft)

Products in the IPX7 Waterproof Rating protection category should be able to withstand submersion of the product in up to 3 feet of water for a period of 30 minutes or less.

Protection at this level was tested for a period of 30 minutes at a depth of at most 3.28ft to the bottom of the product and at least 5.9in from water level to the top of the protective layer.

Product Example: Anova WiFi Precision Cooker

IPX8 Waterproof Rating

(Immersion of beyond 3 ft)

Warning: Equipment that qualifies for for continuous immersion should be specifically stated by the manufacturer to ensure warranty validity.

This generally means that the product should be hermetically sealed (air tight).

With certain products or equipment this can mean that “some” water can enter the protective enclosure but the protection level should still prevent any harmful effect.

Products in the IPX8 Waterproof Rating protection category should be able to withstand vertically falling water in the form of a spray out to a 60° angle from vertical.

Protection at this level was tested in continuous immersion of water at a depth specified by the manufacturer generally up to 9.84ft.

Product Example: Floating Waterproof Phone Case with Audio Cord
