IPsuojausmerkinnät

IPsuojausmerkinnät refers to the Ingress Protection (IP) rating system used to classify the degree of protection provided by enclosures against the ingress of solid objects and water. This system is standardized internationally by the IEC (International Electrotechnical Commission) in IEC 60529.

An IP rating consists of two digits. The first digit indicates the level of protection against solid objects, such as dust and other particulates. This digit ranges from 0 to 6, with 0 offering no protection and 6 providing complete protection against dust. Higher numbers generally signify better protection against intrusion by foreign bodies.

The second digit indicates the level of protection against water. This digit ranges from 0 to 9, with 0 offering no protection and 9 offering protection against high-pressure hot water jets. Similar to the first digit, higher numbers denote enhanced water resistance. For example, an IPX4 rating means the device has some protection against splashing water, while an IPX7 rating indicates it can be immersed in water up to 1 meter for a limited time.

When a digit is not applicable or not tested, it is often replaced by an 'X'. For instance, IPX4 means the device's protection against solids has not been rated, but it offers protection against water splashing. These markings are crucial for selecting appropriate equipment for specific environments, ensuring safety and durability in various industrial, commercial, and domestic applications.
