IP (Ingress Protection) and IK (Impact Protection) Ratings for Electrical Enclosures [IP44 + IK10]

Testing IP (Ingress Protection) and IK (Impact Protection) ratings for electrical enclosures is one of the specialized services we offer. We can perform IP44 and IK10 tests not only in our laboratory but also on-site. The IP and IK classifications specify the level of protection that electrical enclosures provide against unwanted objects, dust, water, and mechanical impacts.

IP Rating Testing:

IP ratings consist of two digits. The first digit indicates protection against dust and solid objects, while the second digit indicates protection against water. The following steps outline how to test the IP rating of an electrical enclosure:

• Testing dust protection (IP5X or IP6X): Specific dust particles of varying sizes and consistencies are used to attempt penetration into the enclosure. The IP rating will indicate the guaranteed level of dust protection.
• Testing protection against solid objects (IP1X to IP4X): Cylindrical objects of specified dimensions are inserted into the enclosure to assess protection against foreign objects. For example, in an IP4X test, a 1 mm steel needle is inserted into every possible opening with a specified force. The IP rating will indicate the guaranteed level of protection against unwanted objects.
• Testing water resistance: Different amounts of water at varying pressure levels are directed at the enclosure to determine whether water ingress occurs. The IP rating specifies the guaranteed level of water protection. Note: If an empty enclosure is tested for certification, no water should be found inside!

IK Rating Testing:

The IK rating indicates how well an electrical enclosure withstands mechanical impact. This is typically tested using a pendulum hammer or a similar impact device.

Here are the basic steps for IK rating testing:

• Place the electrical enclosure on a stable surface.
• Use a hammer with a known energy level and strike different parts of the enclosure.
• Assess the damage and record the energy level at which the enclosure still meets the required IK rating.

The IK rating ranges from 0 to 10, where 0 means no impact protection, and 10 indicates the highest level of protection. It is important to follow the specific test procedures and standards applicable to electrical enclosures. IK10 or even IK10+ is commonly used.

Cost of IP44 and IK10 Testing:

An IP44 and IK10 test, including a comprehensive English test report, costs €2,485.00 all-in. Testing can also be conducted on-site if required.
