There are two sides of the importance of IP rating, one for the buyer/user and one for the manufacturer. When knowing the IP rating of a product the buyer/user can feel safe in knowing how to use an electrical component in specific environments and applications. Instead of buying a product that only states that it is waterproof, which doesn’t indicate what level of water resistance they are referring to, an IP rating will clearly show the amounts of water and from which angles the product is protected from intrusion. Then it’s simple to understand in what type of environment an object is suitable to be used.
For a manufacturer, an IP rating is important from a lot of perspectives. They can rightfully claim that a product is waterproof after the object has undergone the necessary tests to get the required IP rating. It gives a product a larger amount of confidence and proof for the user that the solution will meet their demands.
The IP rating test can only be performed by an independent and certified company. After the mandatory testing is done, the solution will be given a rating that shows how well it is protected against solids and liquids. These test cannot be conducted by the manufacturer them self, which gives the whole rating system more clout and credibility.
