Water and dust IP ratings: What does IP68 mean?

Water and dust IP ratings: What does IP68 standard mean?

Currently, IP68 is a common standard when it comes to water and dust resistance of electrical equipment, especially in the cable manufacturing industry. IP specifications are a water and dust resistance rating system based on the European standard IEC 60529, established by the International Electrotechnical Commission (IEC).

IP stands for "Ingress protection", this standard represents the ability to protect equipment from the intrusion of solids and liquids when the device is exposed.

IP 68 standard for electric appliances

Meaning of the two numbers following IP

• The first number

The first number following IP represents the protective ability of the outer sheath, helping to prevent solid objects from penetrating into electrical equipment, rated on a scale from 0 to 6.

LEVELCONTENTEFFECT
0No protectionThere is no protection against contact and penetration by objects.
1Protected against solid foreign objects of 50 mm Ø and greaterLarge surface of an object, such as the back of a hand, but incapable of resisting contact with a body part.
2Protected against solid foreign objects of 12,5 mm Ø and greaterFingers or similar objects.
3Protected against solid foreign objects of 2,5 mm Ø and greaterEquipment, thick wires, etc.
4Protected against solid foreign objects of 1,0 mm Ø and greaterMost wires, screws, etc.
5Dust-protectedDoes not provide complete protection against dust ingress but ensures that dust ingress is not in quantities large enough to affect the normal operation of the equipment, providing complete protection against exposure.
6Dust-tightDo not allow dust to enter; completely protected from exposure.

• The second number

The remaining number after “IP” rates the protection of the case against liquid ingress and uses a scale of 0 to 8.

LEVELCONTENTTESTINGDETAILS
0No protection__
1Protected against vertically falling water dropsVertically falling drops shall have no harmful effectsTesting time: 10 minutes
This is equivalent to 1 mm of rain falling every minute
2Protected against vertically falling water drops when enclosure tilted up to 15°Vertically falling drops shall have no harmful effects when the enclosure is tilted at any angle up to 15° on either side of the vertical.Testing time: 10 minutes
The equivalent of 3 mm of rain falling every minute
3Protected against spraying waterWater sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects.Testing time: 5 minutes
Water volume: 0.7 liters per minute
Pressure: 80–100 kPa
4Protected against splashing waterWater splashed against the enclosure from any direction shall have no harmful effects.Testing time: 5 minutes
Water volume: 10 liters per minute
Pressure: 80–100 kPa
5Protected against water jetsWater projected in jets against the enclosure from any direction shall have no harmful effects.Testing time: minimum 3 minutes
Water volume: 12.5 liters per minute
Pressure: 30 kPa from 3 m
6Protected against powerful water jetsWater projected in powerful jets against the enclosure from any direction shall have no harmful effects.Testing time: minimum 3 minutes
Water volume: 100 liters per minute
Pressure: 100 kPa from 3 m
7Protected against the effects of temporary immersion in water.Ingress of water in quantities causing harmful effects shall not be possible when the enclosure is temporarily immersed in water under standardized conditions of pressure and time.Testing time: 30 minutes
The lowest immersion point of an enclosure with a height of less than 850 mm is 1000 mm below the water level, and the highest point of an enclosure with a height of 850 mm or more is 150 mm below the water level.
8Protected against the effects of continuous immersion in water.Ingress of water in quantities causing harmful effects shall not be possible when the enclosure is continuously immersed in water under conditions which shall be agreed between manufacturer and user, but which are more severe than for numeral 7.Test time: continuous immersion in water
Depth specified by the manufacturer, usually a maximum of 3 m

The cables meeting the IP68 standard

The IP68 standard plays an important role in ensuring that electrical cables operate stably, avoiding problems in conditions of dust, humidity, and even water immersion. This standard is necessary for cables that require operation in harsh outdoor environments or areas with high humidity.

At HELUKABEL, we provide cables that meet IP68 standards with effective water and dust resistance. You can refer to some of the following products:

HELUPOWER® H07RN-F LS0H cable
HELUPOWER® AQUATIC-750-BLUE cable
HELUKABEL Tauchflex-R cable
HELUKABEL Tauchflex-FL

These cables meet waterproof and dustproof requirements, suitable for use in places that are frequently damp or areas with a large amount of stagnant water. Especially, our HELUPOWER® AQUATIC-750-BLUE cables can even be used under seawater, which were provided for Sun Group's "Sun Signature Show" Water Music Stage project, you can read more about this project HERE .

In addition to water resistance and dust resistance standards, we, HELUKABEL, also provide products that meet many other requirements such as fire-resistant, flame retardant, high-temperature resistance, UV resistance, etc. If you need in-depth advice on the right cables for your application, please contact our engineers for instant support.
