IP Rating

Significance: IP Rating

What is IP Rating?

IP rating, also known as International Protection Rating, is a standard that defines the degree of protection of an electrical device against various environmental factors. Think dust, moisture and liquids. The rating is expressed in two numbers, e.g. IP67.

The first number represents the degree of protection against solid matter such as dust, with numbers ranging from 0 to 6, with 6 offering the highest level of protection.

The second figure represents the degree of protection against liquids, with numbers from 0 to 9, where 9 provides the highest level of protection.

lighting with IP67-classificatie like een LED hamburgerlamp for example, is protected against dust that could damage the device. It is also protected from immersion in water up to a depth of 1 meters for up to 30 minutes.

It is important to note that the IP classification system is only relevant to electrical devices. It is also important to check the classification of a device before purchasing it. This ensures that it meets your environmental protection requirements.

What is the difference between each IP rating?

The specific level of protection provided by each IP classification is defined as follows:

First digit (protection against solid materials):

IP coding:Protection against:Meaning:
0xNo protection
1xLarge objectsProtection against accidental, superficial contact with the hand. Protection against the penetration of solid objects larger than 50 mm
2xMedium-sized objectsProtection against contact with the finger. Touch-safe only for measuring devices. Protection against the penetration of solid objects larger than 12.5 mm.
3xSmall objectsProtection against contact with an implement. Touch-safe only for measuring devices. Protection against the penetration of solid objects larger than 2.5 mm
4xPointed objectsProtection against contact with an implement. Protected against contact with a wire. Protection against the penetration of solid objects larger than 1 mm.
5xDust protectionTouch-safe because the housing is completely sealed. Not complete protection against dust but sufficient not to impede proper operation
6xDust-freeTouch-safe because the housing is completely closed. Complete protection against dust.

Second number (protection against liquids):

IP coding:IEC:Protection against:Meaning:
0IP-X0No protection
1IP-X1Drip seal type INo damage if subjected to vertical drops
2IP-X2Drip-proof type IINo damage if drops fall at an angle of 15
3IP-X3SplashproofNo damage if sprayed (10 1/min) at an angle of -60° to 60
4IP-X4WatertightNo damage if sprayed (10 1/min) at any angle
5IP-X5Spray-proofNo damage if sprayed (12.5 1/min) at any angle
6IP-X6Water-resistantNo water penetration if sprayed (100 1/min) at any angle
7IP-X7Immersion-proofNo water penetration when immersed (30 min at 1 m)
8IP-X8WaterproofRemains usable under water under specified conditions
9IP-X9MoistureproofRemains usable at humidity levels over 90% or spraying under high pressure
 

Which values are suitable for outdoor use?

The correct IP rating for outdoor use depends on the specific environmental conditions to which the device will be exposed. In general, an IP65 rating or higher is recommended for outdoor use. This is because it provides protection against low-pressure water jets from all directions and limited protection against dust. An IP67 rating provides even higher protection against both dust and water. This makes it suitable for outdoor use in harsh conditions such as heavy rain or near water. For example, if the device is used near a swimming pool or in a marine environment, a may IP68-classificatie, which offers protection against continuous immersion in water, are necessary.

It is also important to note that the IP classification system is only relevant to electrical devices. It does not protect against mechanical or other environmental factors, such as wind or temperature. So it is always best to consider all environmental factors when selecting an outdoor device.
