IP Ratings : Explained in Details

IP Ratings

Many electrical products use IP Ratings to protect against different environment object such as water and dust. There is a different type of IP Ratings available to protect against the different object. Moreover, we can separate these different object in solids and liquids. Finally, we are discuss the use of IP Ratings in our product like smartphones, smartwatch and headphones.

What is an IP Rating? Or called it Ingress Protection.

The IP rating or IP code classifies the degree of security provided by the insertion. Which is for electrical devices with rated voltage not exceeding 72.5 kV. Additionally, IP Ratings is established by the international standard EN 60529 (British Standard BS EN 60529:1992).

Moreover, this standard defines the level of sealing effectiveness against “penetration or ingress” i.e. infiltration of foreign bodies such as tools, dirt and liquid water. To get more information about this IP code ratings. First you need to understand the value of the two digit in name IP Ratings.

What do the two digits in an IP Rating mean?

The rating consists of IP characters followed by two digits, the higher the number the better the protection. Sometimes the number is replaced by X, indicating that the enclosure is not rated for that specification.

Speaking of digits, the first digit suggested the level of safety provided by enclosures against the entry of solid foreign objects, instruments or fingers. Which may be dangerous if they come in contact with electrical conductors or moving parts, airborne dirt and dust which may damage the circuitry.

The second digit suggest the protection of the equipment inside the enclosure against various forms of moisture (drips, sprays, submersion etc).

Following is the reference chart of this digit to understand IP Ratings better.
