WHAT DOES IP CODE MEAN?


What does IP CODE mean?

TheIP Code,International Protection Marking, IEC standard 60529, sometimes interpreted asIngress Protection Marking, classifies and rates the degree of protection provided against intrusion (body parts such as hands and fingers),dust, accidental contact, and water by mechanical casings andelectrical enclosures.It is published by theInternational Electrotechnical Commission(IEC). The equivalent European standard is EN 60529.

The standard aims to provide users more detailed information than vague marketing terms such aswaterproof. IP22 or IP2X are typical minimum requirements for the design of electrical accessories for indoor use.

The digits indicate conformity with the conditions summarized in the tables below.The digit0is used where no protection is provided. The digit is replaced with the letterXwhen insufficient data has been gathered to assign a protection level.

First digit: Solid particle protection

The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid foreign objects.

Level sized

Description

0

No protection against contact and ingress of objects

1

>50mm

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

2

>12.5mm

Fingers or similar objects

3

>2.5mm

Tools, thick wires, etc.

4

>1mm

Most wires, slender screws, large ants etc.

5

Dustprotected

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

Dusttight

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

Second digit: Liquid ingress protection

The second digit indicates the level of protection that the enclosure provides against harmful ingress of water.The ratings for water ingress are not cumulative beyond IPX6. A device which is compliant with IPX7, covering immersion in water, need not be compliant with IPX5 or IPX6, covering exposure to water jets. A device which meets both tests is indicated by listing both tests separated by a slash, e.g. IPX5/IPX7.

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: 10minutes
Water equivalent to 1mm 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: 2.5minutes for every direction of tilt (10 minutes total)
Water equivalent to 3mm 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 5minutes[2]
Water volume: 10litres per minute
Pressure: 50–150kPa

For an oscillating tube:

Test duration: 10 minutes

Water Volume: 0.07 l/min 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. Test 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 (6.3mm) against enclosure from any direction shall have no harmful effects.

Test duration: 1 minute per square meter for at least 15min.
Water volume: 12.5Lt/min
Pressure: 30kPa at distance of 3m

6

Powerful water jets

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

Test duration: 1 minute per square meter for at least 3minutes
Water volume: 100litres per minute
Pressure: 100kPa at distance of 3m

6K

Powerful water jets with increased pressure

Water projected in powerful jets (6.3mm 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 3minutes[citation needed]
Water volume: 75litres per minute
Pressure: 1000kPa at distance of 3m

7

Immersion, up to 1m 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 1m of submersion).

Test duration: 30minutes Tested with the lowest point of the enclosure 1000mm below the surface of the water, or the highest point 150mm below the surface, whichever is deeper.

8

Immersion, 1m 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 manufacturer, generally up to 3m

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 upright, no turntable required, and are tested freehand for at least 3 minutes at distance of 0.15–0.2 m.

There are specific requirements for the nozzle used for the testing.

This test is identified as IPx9 in IEC 60529.

Test duration: 30 seconds in each of 4 angles (2 minutes total)

Water volume: 14–16litres per minute
Pressure: 8–10MPa (80–100bar) at distance of 0.10–0.15m
Water temperature: 80C

(All tests with the letter "K" are defined by ISO 20653 (replacing DIN 40050-9) and are not found in IEC 60529, except for IPx9 which is the same as the IP69K water test.)

All our membrane keypads have an IP65 Degree of Protection (provided that the input slot of the tail to the equipment is sealed), and according to the model and customer requirements we can manufacture keyboards that comply with the IP67, which guarantees a very high level of protection. protection, durability, and good performance over time.

Each membrane keyboard is different, contact us and we will find the best solution for your project!
