IP Ratings Chart | Waterproof Fully Explained

2

What are IP Ratings?

IP stands for ingress protection.  IP ratings are a scale that determines an electrical objects ability of preventing solid or liquid materials from entering itself.

These IP ratings are prescribed by the International Electrotechnical Commission (IEC).

The code that spells out the standard for IP ratings is the IEC 60529 IP CODE.

IP ratings are determined by a preceding “IP” and the two numbers that follow.  The first being a number indicating the amount of protection from solids.  The second number determines the protection from liquids.

For example, an object rated IP67 on the IP Ratings chart would be a product that is (6) dust tight and (7) protected from temporary water immersion.

Use the IP chart from the IEC below to determine the multitude of ratings that can be obtained for varying products.

If you are looking for the IPX Ratings Chart for waterproofing only and products that have not been tested on solids, keep reading.

IP Ratings Chart

What do IPX Ratings Mean?

The X in IPX ratings means that the product has not been tested on solids and therefore the X takes the place of the first number in the rating.

The number that follows the X is the waterproof rating.

The waterproof ratings are also dictated by the international code published by the IEC.

As previously stated, ingress simply means a going in or entering.  There for IP references the level of protection needed to prevent entering.

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.

IPX0 Rating

Offers no water protection at all.

Product example: There are lots of products that offer not protection from water.  Just picture a paper bag sitting in a puddle on a rainy day.

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

IPX4 Rating

(Splashing Water)

Products in the IPX4 Waterproof Rating protection category should be able to withstand water splashing against the protective layer from any direction without harmful effect.

Protection at this level was tested for a period of 5 minutes at a volume of about 2.64 gallons per minute at a pressure between 11.6 psi to 14.5 psi.

Product Example: EcoSurvivor Waterproof Earbuds

IPX5 Rating

(Water Jets)

Products in the IPX5 Waterproof Rating protection category should be able to withstand water from about a one quarter inch nozzle against the protective layer from any angle.

Protection at this level was tested for a period of 15 minutes at a volume of about 1.84 gallons per minute at a pressure of 4.35psi from a distance of 9.84ft.

Product Example: Rechargeable 90,000 Lumens LED Spotlight

IPX6 Rating

(Powerful Water Jets)

Products in the IPX6 Waterproof Rating protection category 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 26 gallons per minute at a pressure of 14.5 psi from a distance of 9.84ft.

Product Example: Bluetooth Shower Speaker

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 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
