The IP rating evaluates and classifies the degree of protection, with the first digit referring to the protection against the intrusion of solid particles (such as sand and dust) and the second digit regarding the impermeability against liquids. It might be useful to know that an IP20 product has no protection against the entry of liquids whilst an IP44 product is splash-proof and thus will be suitable for a bathroom. An IP65 product is protected from jets of water and totally safeguarded against the ingress of dust and sand, hence it can better withstand rain and inclement weather, making it suitable for outdoor environments.  Some 9010novantadieci recessed products are shown as IP20-IP44, meaning that they obtain an IP44 rating only when completely installed.
