Back to IP-classification table

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

Back to IP-classification table

IP 2X testing involves pressing a standardised 12 mm diameter test finger with a force of 10 N, and a 12,5 mm sphere with a force of 30 N, against all openings in the enclosure. For acceptance, the sphere must not fully enter the enclosure and there must be a satisfactory distance between the test finger and dangerous live parts and moving parts

IP 5X Back to IP-classification table

Items to be tested for IP 5X enclosures are exposed to fine-grained circulating talcum powder in a dust chamber for 2- 8 hours, with the exposure time being determined by the test conditions for the specific item. This test is performed with a maximum depressure of 20 mbar inside the item under test, and with a maximum extraction rateof 60 volumes/hour. 

If specific product standards so permit, testing is performed without depressure for eight hours.

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

For acceptance for Class IP 5X, dust must not penetrate into the item in such quantities, or in such a position, as to prevent satisfactory operation of the item or to present a safety risk. There must also be a safe distance from the wire to live or moving parts.

IP 6XBack to IP-classification table

Items to be tested for IP 6X enclosures are exposed to fine-grained circulating talcum powder in a dust chamber for 2- 8 hours, with the exposure time being determined by the test conditions for the specific item. This test is performed with a maximum depressure of 20 mbar inside the item under test, and with a maximum extraction rateof 60 volumes/hour. 

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

For acceptance for Class IP 6X, dust must not penetrate into the item. There must also be a safe distance from the wire to live or moving parts.

The enclosure is exposed to water spray from an oscillating tube nozzle, with each spray jet giving a flow rate of 0.07 l/min, for ten minutes. Alternatively, a standardised spray nozzle, producing a spray of 10 l/min, may be used. If this spray nozzle is used, the exposure time is 1 min/m², with a minimum of five minutes. Regardless of the type of test equipment, water spraying is limited to ±60° from the vertical.

Acceptance for Class IP X3 requires no water to have penetrated into the item in such a quantity, or in such a position, as to prevent satisfactory operation of the item or to present a safety risk.
