What is IP65, IP66, IP67?

X

—

X means there   is no data available to specify a protection rating with regard to this   criterion.

0

—

No protection   against contact and ingress of objects

1

>50 mm
  2.0 in

Any large   surface of the body, such as the back of a hand, but no protection against   deliberate contact with a body part

2

>12.5 mm
  0.49 in

Fingers or   similar objects

3

>2.5 mm
  0.098 in

Tools, thick   wires, etc.

4

>1 mm
  0.039 in

Most wires,   slender screws, large ants etc.

5

Dust protected

Ingress of   dust is not entirely prevented, but it must not enter in sufficient quantity   to interfere with the satisfactory operation of the equipment.

6

Dust-tight

No ingress of   dust; complete protection against contact (dust-tight). A vacuum must be   applied. Test duration of up to 8 hours based on airflow.

1

Dripping water

Dripping water   (vertically falling drops) shall have no harmful effect on the specimen when mounted   in an upright position onto a turntable and rotated at 1 RPM.

Test duration:   10 minutes

Water   equivalent to 1 mm (0.039 in) rainfall per minute

2

Dripping water   when tilted at 15°

Vertically   dripping water shall have no harmful effect when the enclosure is tilted at   an angle of 15° from its normal position. A total of four positions are   tested within two axes.

Test duration:   2.5 minutes for every direction of tilt (10 minutes total)

Water   equivalent to 3 mm (0.12 in) rainfall per minute

3

Spraying water

Water falling   as a spray at any angle up to 60° from the vertical shall have no harmful   effect, utilizing either: a) an oscillating fixture, or b) A spray nozzle   with a counterbalanced shield.

Test a) is   conducted for 5 minutes, then repeated with the specimen rotated horizontally   by 90° for the second 5-minute test. Test b) is conducted (with shield in   place) for 5 minutes minimum.

For a spray   nozzle:

Test duration:   1 minute per square meter for at least 5 minutes^[6] Water volume: 10 liters per   minute (0.037 impgal/s) Pressure: 50–150 kPa (7.3–21.8 psi)

For an   oscillating tube: Test duration: 10 minutes Water volume: 0.07 liters per   minute (0.00026 impgal/s) per hole

4

Splashing of   water

Water   splashing against the enclosure from any direction shall have no harmful   effect, utilizing either:

a) an   oscillating fixture, or b) A spray nozzle with no shield. Test a) is   conducted for 10 minutes. b) is conducted (without shield) for 5 minutes   minimum.

Oscillating   tube: Test duration: 10 minutes, or spray nozzle (same as IPX3 spray nozzle   with the shield removed)

5

Water jets

Water   projected by a nozzle (6.3 mm (0.25 in)) against enclosure from any   direction shall have no harmful effects.

Test duration:   1 minute per square meter for at least 3 minutes

Water volume:   12.5 litres per minute Pressure: 30 kPa (4.4 psi) at distance   of 3 meters (9.8 ft)

6

Powerful water   jets

Water   projected in powerful jets (12.5 mm (0.49 in)) against the   enclosure from any direction shall have no harmful effects.

Test duration:   1 minute per square meter for at least 3 minutes

Water volume:   100 liters per minute (0.37 impgal/s) Pressure: 100 kPa   (15 psi) at distance of 3 meters (9.8 ft)

6K

Powerful water   jets with increased pressure

Water   projected in powerful jets (6.3 mm (0.25 in) nozzle) against the   enclosure from any direction, under elevated pressure, shall have no harmful   effects. Found in DIN 40050, and not IEC 60529.

Test duration:   at least 3 minutes^{[citation needed]}

Water volume:   75 liters per minute (0.27 impgal/s) Pressure: 1,000 kPa   (150 psi) at distance of 3 meters (9.8 ft)

7

Immersion, up   to 1 meter (3 ft 3 in) depth

Ingress of   water in harmful quantity shall not be possible when the enclosure is   immersed in water under defined conditions of pressure and time (up to 1   meter (3 ft 3 in) of submersion).

Test duration:   30 minutes.^[4]

Tested with   the lowest point of the enclosure 1,000 mm (39 in) below the   surface of the water, or the highest point 150 mm (5.9 in) below   the surface, whichever is deeper.

8

Immersion, 1   meter (3 ft 3 in) or more depth

The equipment   is suitable for continuous immersion in water under conditions which shall be   specified by the manufacturer. However, with certain types of equipment, it   can mean that water can enter but only in such a manner that it produces no   harmful effects. The test depth and duration is expected to be greater than   the requirements for IPx7, and other environmental effects may be added, such   as temperature cycling before immersion.

Test duration:   agreement with manufacturer

Depth   specified by the manufacturer, generally up to 3 meters (9.8 ft)

9K

Powerful   high-temperature water jets

Protected   against close-range high pressure, high-temperature spray downs.

Smaller   specimens rotate slowly on a turntable, from 4 specific angles. Larger   specimens are mounted in the intended position when being used, no turntable   required, and are tested freehand for at least 3 minutes at a distance of   0.15–0.2 meters (5.9 in–7.9 in).

The specific   requirements for the test nozzle are shown in figures 7, 8, & 9 of IEC   (or EN) 60529.

This test is   identified as IPx9 in IEC 60529.

Test duration:   Fixture: 30 sec. in each of 4 angles (2 min. total), Freehand: 1 min/m², 3 min. minimum

Water volume:   14–16 liters per minute (0.051–0.059 impgal/s) Pressure: 8–10 MPa   (80–100 bar) at distance of 0.10–0.15 meters (3.9 in–5.9 in)   Water temperature: 80 °C (176 °F)
