Introduction to IP Protection Level Certification Testing

Testing standards

IP (Ingress Protection) certification is used to measure the protective ability of electrical equipment enclosures against foreign objects and water. This certification is developed by the International Electrotechnical Commission (IEC) with standard number IEC 60529. The IP protection level consists of two digit codes, with the first digit representing the dust protection level, ranging from 0 to 6, for a total of 7 levels:

Level 0: No protection, the equipment does not have a dedicated dust-proof design.

Level 1: Prevent objects larger than 50mm from entering, such as accidental hand contact.

Level 2: Prevent objects larger than 12mm from entering, such as accidental touch with fingers.

Level 3: Prevent the intrusion of objects larger than 2.5mm, such as tools.

Level 4: Prevent objects larger than 1.0mm from entering, such as mosquitoes, insects, etc.

Level 5: Unable to completely prevent dust intrusion, but the amount of dust intrusion will not affect the normal operation of the equipment.

Level 6: Completely prevents dust from entering.

The second number represents the waterproof level, with a total of 9 levels from 0 to 8:

Level 0: No protection, equipment without specialized waterproof design.

Level 1: Prevent water droplets from entering, and ensure that vertical water droplets from the device have no impact.

Level 2: Prevent dripping water from entering even when tilted at 15 degrees.

Level 3: Prevent the intrusion of sprayed water, rainwater, or water sprayed in a direction with a vertical angle less than 50 degrees.

Level 4: Prevent splashing water from entering and prevent splashing water from all directions from entering.

Level 5: Prevent the intrusion of water from large waves, and prevent the intrusion of water rapidly sprayed from large waves or spray holes.

Level 6: To prevent the intrusion of large waves of water, the equipment can still ensure normal operation under certain time or water pressure conditions.

Level 7: Prevent the intrusion of submerged water, ensure the equipment operates normally under certain water pressure conditions when submerged indefinitely in water.

Level 8: To prevent the impact of sinking, the equipment can still work normally after being submerged in water for a long time.

Applicable products

Consumer electronics products: devices such as smartphones, smartwatches, tablets, etc., often used outdoors, may be affected by rainwater and dust. By passing the IP protection level certification test, the reliability of the product in different environments can be ensured, and the product quality can be improved.

Industrial equipment: motors, control cabinets, sensors, and other industrial equipment typically operate in harsh industrial environments and face risks such as dust, water splashes, and rain. IP protection level certification testing can help enterprises ensure the normal operation of equipment and reduce failures caused by environmental factors.

Automotive components: car headlights, onboard computers, electronic devices in the engine compartment, etc., come into contact with water and dust during the driving process of the car. Conducting IP protection level certification testing can improve the durability of automotive components and ensure driving safety.

Outdoor equipment: Street lamps, surveillance cameras, outdoor speakers, and other devices that are exposed to the outdoors for a long time need to have good dust and water resistance performance. IP protection level certification testing ensures that these devices operate stably under various harsh weather conditions.
