Understanding IP67 Rating and how it differs from IP65 & IP66

IP67 rating

In order to ensure that the device will work in the environment it is used in, IP ratings are a crucial factor to take into account when choosing a device. Many devices have an IP rating to show that they are protected against dust and water, which can often impede operational abilities and lead to system failures. An IP rating ensures that operational ability is not hampered and that the risk of system failure is reduced.

What is IP67 Rating?

An IP Rating (Ingress Protection Rating) is used to categorize the various levels of encasing effectivity that an electrical enclosure provides against foreign materials including objects, water, dirt, etc. The “IP” prefix is followed by two numbers to indicate the degree of protection. Number six denotes the level of protection against dust, which means it is safe to use electronics inside of the enclosure, as there is no risk of electric shock or failure due to dust. The system is protected against submersion in deep water at pressures of up to 1 meter, according to the number seven.

According to the electrical enclosure rating of IP67, a container is capable of shielding a device inside from the damaging effects of dust and water. An enclosure with an IP67 rating offers dust-tight defense against solid ingress from sources like wind-blown dirt. When you consider that IP67 enclosures have strong water resistance against everything from hose sprays to brief submersion, it is clear why designers frequently specify them for their products.

Applications for which IP67 rating is appropriate

One of the highest levels of protection that an IP rating can provide is IP67. It makes sure a device is totally dustproof and waterproof for a short period of time. As a result of this rating, it is possible to have a total defense against the entry of dust and airborne particles. Additionally, it is also possible to be protected from liquids and water immersion up to and including one meter of water immersion.

The following applications are especially suitable for an IP67 enclosure:

  • Medical, industrial, and laboratory equipment are just a few examples of outdoor utility devices that require protection from moisture and dust in order to function properly, especially in areas with heavy precipitation.
  • Scientific devices that must withstand adverse weather conditions
  • Controls for industrial machinery that is frequently washed with high pressure
  • Parts of outdoor security systems that must be easily accessible under various circumstances
  • Additionally, equipment for the military that is intended to be used in a wide range of situations is a perfect target for an IP67-rated enclosure.

Difference Between IP65, IP66, and IP67 Ratings?

Each digit in a standard IP code is denoted by its meaning in the IP rating table. It gives a clear indication of the particular risks and scenarios, as well as how much and in what kind of environment the mechanical or electrical components enclosure of a product needs to be protected.

IP67 vs IP65

When comparing IP67 and IP65, a relatively high waterproofing rating is contrasted with a lower one. Regarding waterproofing protection, IP67 is superior to IP65. This is because IP67 certification means that the device can withstand heavy rain and be completely submerged in up to 1 meter of water for up to 30 minutes, while IP65 only offers protection from low-pressure jets of water from all directions. Furthermore, the IP67 rating has higher dust protection than IP65, which makes it suitable for outdoor use and applications that require increased durability.

IP67 vs IP66

When comparing IP67 and IP66 waterproofing ratings, a relatively high rating is contrasted with a lower one. IP67 is an Ingress Protection rating that signifies a higher level of water protection than IP66. IP67 is certified for complete protection against dust and immersion up to 1 meter for 30 minutes, while IP66 is certified against powerful water jets and complete protection from dust. Thus, when making a comparison between IP67 and IP66, it is clear that the higher rating provides an increased level of protection from water and dust.

When a product is marked with both IP66 and IP67, it means that it satisfies the protection standards for both short-term and continuous immersion as well as water jets.

IP Rating Protection Description Test Method Measurement
IP65 Protection against water jet No harm should come from water sprayed from any direction by a nozzle (6.3 mm) against an enclosure. At least 15 minutes must pass the test.


12.5 liters of water per minute.

30 kPa of pressure at a 3-meter distance

IP66 Protection against strong water jets Strong jets of water with a 12.5 mm nozzle pushed on the enclosure from any angle must not cause any damage. Minimum of three minutes for the test.


100 liters of water per minute in volume

100 kPa of pressure at a 3-meter distance

IP67 Protection against immersion up to one meter When the enclosure is submerged in water under specific pressure and time parameters, no dangerous water should enter (up to 1 m of submersion). Maximum of 30 minutes for the test


Immersion is at least 15 cm deep at the top of the device and at least 1 m deep at the bottom.


Wrapping Up

For a product to perform at its best, businesses should ensure that it satisfies customer requirements and offers protection from the elements. Additionally, businesses should ensure that the product meets safety and performance standards, so as to guarantee customer satisfaction. The products with an IP67 rating are particularly significant since they provide stronger protection against both solids and liquids at once.
