Protection Degrees (IP Code) (Electrical Equipment) Tests with Enclosures


Input Protection Test

Many products go through various tests before they reach the market. These tests include product safety testing, electromagnetic compatibility, vibration testing, and more

 

 

According to EN 60529 / A1 standard, the results of the experiments conducted to determine the IP protection class during the contact of electrical products, especially outdoor electrical products, are determined by our PTC laboratory.

 

Products used indoors or outdoors are generally tested for ve ingress ere of the product, ie the resistance of the product to water, dust and foreign substances. There are various reasons for the input test, including security, functionality, and product marketing.


IP 1X

Testing for IP1X enclosures involves pressing a 50 mm diameter sphere with a force of 50 N against all openings in the enclosure. If the sphere does not enter the enclosure fully and there is a satisfactory distance from the dangerous live parts and moving parts, the product is approved.


IP 2X

The IP 2X test includes a standard 12 mm diameter test finger against a 10 N force against all openings in the enclosure and a sphere of 12.5 mm with a force of 30 N. For acceptance, the sphere must not enter fully into the enclosure and there must be a satisfactory distance between the test finger and the dangerous live parts and moving parts.


IP 3X

The IP 3X test involves pressing a standard test probe in the form of a 2.5 N steel wire against all openings in the housing. With a force of 3 N, the probe must not enter the enclosure for acceptance.


IP 4X


The IP 4X test involves pressing a standard test probe in the form of a 1 mm steel wire with a 1 N force against all openings in the housing. To accept, the probe must not enter the enclosure.


IP 5X

For IP 5X containers, the items to be tested are exposed to fine-grained circulating talcum powder for 2-8 hours in the dust bin; the duration of exposure is determined by the test conditions for the specific product. This test is carried out with a maximum pressure of 60 mbar and a maximum extraction of 60 mbar in the tested product.

If certain product standards permit this, the test is carried out without pressure for eight hours.

In addition to the powder test, 1 mm steel wire is pressed to a force of 1 N to all openings in the enclosure.

In order for class IP 5X to be accepted, dust must not enter the item in such quantities or in such a way as to avoid satisfactory operation of the item or to offer a safety risk. There should be a safe distance from the wire to live or moving parts.


IP 6X

For IP 6X enclosures, the items to be tested are exposed to fine-grained circulating talcum powder for 2-8 hours in the powder container, and the exposure time is determined by the test conditions for the specific product. This test is carried out with a maximum pressure of 60 mbar and a maximum extraction of 60 mbar in the tested product.

In each case, the test is verified by a test engineer to check the test item after the test is completed to determine the test. It is very important that the test engineer is well trained and knowledgeable when conducting the test and reporting the results.

IP X1

The container is exposed to water dripping at a flow rate of 1 mm / minute for 10 minutes.

The adoption of the IPX1 Class requires that no water enters the substance in this amount or in such a case to prevent satisfactory operation of the substance or to offer a safety risk.


IP X2

The container is exposed to dripping water for 4 x 2.5 minutes with a flow rate of 3 x / min.

The enclosure is tested at a constant tilt of 15o from the normal position.

The adoption of Class IP X2 requires that water does not enter the substance in this amount or in such a case, to prevent the substance from working satisfactorily or to offer a safety risk.


IP X3

The container is contacted with a spray of water from each of the pulsating tube nozzles, each having a flow rate of 0.07 l / min for ten minutes. Alternatively, a standard spray nozzle may be used which produces a spray of 10 l / min. If this spray nozzle is used, the exposure time is at least five minutes to 1 min / m². Regardless of the type of test equipment, water spray is limited to ± 60 ° from the vertical.

The adoption of Class IP X3 requires that water does not enter the substance in this amount or in such a case to prevent the substance from working satisfactorily or to offer a safety risk.


IP X4

The housing is contacted with a spray of water from each oscillating tube, each spray nozzle having a flow rate of 0.07 l / min for ten minutes. Alternatively, a standard spray nozzle may be used which produces a spray of 10 l / min. If this spray nozzle is used, the exposure time is at least five minutes to 1 min / m². Water splashes into the enclosure from all directions.

The adoption of Class IP X4 requires that no water enters the substance in this amount or in such a position to prevent the substance from working satisfactorily or to offer a safety risk.


IP X5

The housing is exposed to a jet of water from a nozzle of 6.3 mm diameter at a distance of 2.5 to 3 m from the material tested. The water flow rate is 12.5 l / min which lasts at least three minutes for a period of 1 minute / m².

The adoption of Class IP X5 requires that no water enters the substance in this amount or in such a position in order to prevent the substance from working satisfactorily or to offer a safety risk.


IP X6

The casing is exposed to a water jet from a 12.5 mm diameter nozzle at a distance of 2.5 to 3 m from the material tested. The water flow rate is 100 l / min, applied for at least three minutes for a period of 1 min / m².

The adoption of Class IP X6 requires that no water enters the substance in this amount or in such a position to prevent satisfactory operation of the substance or to offer a safety risk.


IP X7

The test is carried out by immersing the enclosure in water completely in the service position.

The container is immersed in a depth of one meter for 30 minutes.

Adoption of Class IP X7 requires that no water enters the substance in this amount or in such a position to prevent satisfactory operation of the substance or to offer a safety risk.


IP X8

The test is done by immersing the enclosure completely in water.

Test conditions are subject to agreement between the manufacturer and the user.

The adoption of Class IP X8 requires that no water enters the substance in or in such an amount to prevent the substance from working satisfactorily or to offer a safety risk.


IP X9

The housing is subjected to high pressure hot water at different angles for 30 seconds at each angle.

For class IP X9, acceptance requires that no water enters the substance in this amount or in such a case, in order to prevent satisfactory operation of the substance or to offer a safety risk.
