WHAT IS AN IP RATING?
Well it stands for Ingress Protection and it measures a product’s resistance to solids and liquids. This is particularly important when we consider the potential harm that can arise from water meeting electronics. With this in mind, the required IP rating of a product will depend on the product’s application. For example, a light that is going to be used above a shower is far more likely to be subjected to a jet of water than one in a living room, so the bathroom fitting will need to have a higher IP rating.
Each IP rating consists of two digits, the first indicating the protection offered against solids, while the second digit details the protection against liquids. The different ratings can be outlined in this handy chart. We read the first digit and second digit separately to get the solid and liquid rating of the product.
