What is the BS EN 60529:1992?

The BS EN 60529:1992 is an international standard that defines the degrees of protection provided by enclosures for electrical equipment against the intrusion of solid objects and liquids. It is commonly referred to as the "IP code" or "ingress protection code." The IP code system rates the effectiveness of enclosures based on tests that measure their ability to keep out dust, water, and other potentially harmful substances.

The Structure of the IP Code

The IP code consists of two digits, both of which have specific meanings. The first digit represents the level of protection against solid objects, such as dust and dirt. It ranges from 0 to 6, with 0 indicating no protection and 6 indicating complete protection against dust. The second digit represents the level of protection against liquids, such as water. It ranges from 0 to 9, with 0 indicating no protection and 9 indicating protection against prolonged immersion under pressure.

Understanding the IP Code Ratings

Let's take a closer look at some of the common IP code ratings:

IP64: This rating means that the enclosure is protected against dust (level 6) and water splashes from any direction (level 4).

IP68: This rating indicates that the enclosure is fully protected against dust (level 6) and can be submerged in water beyond 1 meter depth for an extended period of time (level 8).

IPX7: The "X" in this rating means that the enclosure's protection against solid objects hasn't been tested or is not applicable. However, it is protected against water immersion up to 1 meter depth for 30 minutes.

Importance of the IP Code

The BS EN 60529:1992 standard and the IP code are crucial in various industries, particularly in designing and manufacturing electrical equipment. They ensure that electrical components are adequately protected against external influences, which can significantly affect their performance and safety. By understanding the IP code ratings, consumers can make informed decisions when purchasing electrical devices for specific environments, such as outdoor applications or humid locations.
