What is an IP rating?

IP (or "Ingress Protection") ratings are defined in international standard EN 60529 (British BS EN 60529:1992, European IEC 60509:1989). They are used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies (tools, dirt etc) and moisture.

 

The standard aims to provide users more detailed information than vague marketing terms such as waterproof. For example, a cellular phone rated at IP68 is "dust resistant" and can be "immersed in 1.5 meters of freshwater for up to 30 minutes". Similarly, an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. IP22 or IP2X are typical minimum requirements for the design of electrical accessories for indoor use.

The digits indicate conformity with the conditions summarized in the tables below. The digit 0 is used where no protection is provided. The digit is replaced with the letter X when insufficient data has been gathered to assign a protection level.

 

The second digit indicates the level of protection that the enclosure provides against harmful ingress of water.[3]Links to an external site. The ratings for water ingress are not cumulative beyond IPX6. A device that is compliant with IPX7, covering immersion in water, need not be compliant with IPX5 or IPX6, covering exposure to water jets. A device that meets both tests is indicated by listing both tests separated by a slash, e.g. IPX5/IPX7.

IP ratings for outdoor lights

IP rating for outdoor lights is key to both the safety and proper functioning of any unit installed where condensation, rain or wind-blown foreign bodies might pose a potential risk to circuitry and users alike. This includes accent lighting and soffit spots, safety or task floods, PIR/security sensor lights and more.

 

    • The following are general industry rules of thumb for outdoor lighting, but it’s always wise to seek manufacturer or supplier advice for your specific application scenario before installation:
    • IPX3 will protect against continuous spray at up to a 60° angle, which is generally considered sufficient in partially enclosed or covered areas.
    • IPX4 is more commonly used as a minimum in more exposed spaces.
    • If the lights are likely to be cleaned using pressurised jets, they should be rated at IPX5 or above.
    • Any lighting intended for immersion (e.g. pond or pool lighting) up to a depth of 1m must be rated at least IPX7, but always check explicitly with the manufacturer before installing any lighting below the surface of the water.
    • Immersion at greater depths will require IPX8, and should again be checked explicitly for precise ingress resistance capabilities before installation.

Waterproof tech has become a big trend in recent years. But how do you know how protected your device is? Most devices use either IP or ATM ratings. Let’s start by talking about IP ratings.
