What is the degree of protection ACC to IEC 60529?

Degree of protection (IP code) is an internationally recognized standard defined by the International Electrotechnical Commission (IEC) in IEC 60529. It specifies the level of protection provided by enclosures of electrical equipment against the intrusion of foreign objects (including dust) and water. The IP code provides crucial information about the ruggedness and durability of electronic devices, especially those used in harsh environments or outdoor settings.

Understanding IP Code

The IP code consists of two digits, each providing specific information about the degree of protection. The first digit indicates the level of protection against solid objects, while the second digit indicates the level of protection against water. Let's delve deeper into each digit's meaning.

First Digit: Protection Against Solid Objects

The first digit of the IP code ranges from 0 to 6 and represents the degree of protection against the ingress of solid objects such as dust, dirt, or human body parts. Here is a breakdown of the levels of protection for each digit:

Level 0: No protection against solid objects.

Level 1: Protection against objects larger than 50mm in diameter.

Level 2: Protection against objects larger than 12.5mm in diameter.

Level 3: Protection against objects larger than 2.5mm in diameter.

Level 4: Protection against objects larger than 1mm in diameter.

Level 5: Dust-protected; limited ingress of dust is permitted, but it must not interfere with the satisfactory operation of the equipment.

Level 6: Dust-tight; no ingress of dust is permitted.

Second Digit: Protection Against Water

The second digit of the IP code ranges from 0 to 9 and represents the degree of protection against the ingress of water. Here is a breakdown of the levels of protection for each digit:

Level 0: No protection against water.

Level 1: Protection against vertically falling drops of water (e.g., condensation).

Level 2: Protection against direct sprays of water up to 15 degrees from vertical.

Level 3: Protection against direct sprays of water up to 60 degrees from vertical.

Level 4: Protection against water splashes from all directions.

Level 5: Protection against low-pressure water jets from all directions.

Level 6: Protection against powerful water jets and waves.

Level 7: Protection against temporary immersion in water up to 1 meter depth for 30 minutes.

Level 8: Protection against continuous immersion in water beyond 1 meter depth, subject to agreed-upon conditions.

Level 9: Protection against high-pressure water jets and steam cleaning.

By looking at the IP code provided by manufacturers, users can determine the suitability of electronic devices in specific environments based on the level of protection against solid objects and water. It is important to note that compliance with the IP code does not guarantee absolute protection but offers a standardized way to communicate device resistance to external elements.

In conclusion, the degree of protection ACC to IEC 60529, as indicated by the IP code, is crucial in assessing the ruggedness and durability of electrical equipment against solid objects and water. Understanding the IP code helps ensure that electronic devices are adequately protected, making them suitable for various environments and applications.
