What is EN 60529 standard?

The EN60529 standard, also known as the International Protection Marking (IP Code), is a classification system developed by the International Electrotechnical Commission (IEC). It provides information on the level of protection provided by enclosures for electrical equipment against intrusion of dust, water, and other foreign objects. The purpose of this standard is to ensure safety and reliability of electrical devices in various environments.

Understanding the IP code

The IP code consists of two digits following the letters "IP". The first digit indicates the level of protection against solid objects such as dust, while the second digit indicates the level of protection against liquids. Each digit has its own scale, ranging from 0 to 6, with higher numbers indicating greater protection. By referring to the IP code, users can determine the suitability of a device for specific conditions and environments.

Protection against solids: First digit

The first digit ranges from 0 to 6 and indicates the degree of protection against solid objects. A rating of 0 means no protection against solids, while a rating of 6 signifies complete protection against dust and other fine particles. For example, an enclosure with a first digit of 4 provides protection against most wires, screws, and similar small objects. Understanding the first digit of the IP code helps consumers choose the appropriate device for their specific needs.

Protection against liquids: Second digit

The second digit of the IP code ranges from 0 to 8 and represents the level of protection against water and other liquids. A rating of 0 offers no protection against liquids, while a rating of 8 signifies protection against continuous immersion in water, even under specified conditions. For instance, a device rated with IPX7 can be submerged in water up to a certain depth and for a specified duration without being damaged. This second digit is crucial for determining if a device is suitable for use in wet or outdoor environments.
