Ingress Protection tests are conducted in accordance with IEC We will then measure the effects of this exposure, and give the product an appropriate IP rating. The level of protection of a product is signified by a number e. IP67 where the first number is the ingress protection against solid bodies, and the second number is protection against liquids.

But what does it mean? While they give product marketers plenty of ways to massage their message, these terms can lead to major confusion for the rest of us. Is my water-resistant phone as well protected from rain as my weatherproof Bluetooth headphones?
Can I take either of them scuba diving with me? Note: Please never scuba dive with your phone. An IP rating may look something like this:. IP57 As you can see, it consists of two digits. The first digit tells us how well the product is protected from solid stuff. The second one is about resistance to water. The higher the rating, the better a product is protected. IP rating is only officially given to a product that undergoes special testing by a certified, independent company.
If a product can survive both scenarios, it gets a dual rating — e. Does it mean the company is lying to me? Are they trying to sell me some junk?! All that means is that a product did not go through this specific IP test.
IP rating can also be missing if the company went for a different certification or rating standard. Look for other quality marking that proves the product is water- or dust-resistant.

Waterproof or water resistant? What’s behind an IP rating?
As defined in international standard IEC , it classifies the degrees of protection provided against the intrusion of solid objects including body parts like hands and fingers , dust, accidental contact, and water in electrical enclosures. The standard aims to provide users more detailed information than vague marketing terms such as waterproof. The digits characteristic numerals indicate conformity with the conditions summarized in the tables below. For example, 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 2X are typical minimum requirements for the design of electrical accessories for indoor use.
IEC 60529 IPX7 Immersion Chamber Smart Water Supply and Control System for IPX1 to IPX8
Ingress protection testing tests the degree of protection an enclosure provides against intrusions. One such set of ingress protection tests involves immersing the equipment under test EUT , in water. The solid particles can include probes, fingers and dust testing. The second digit in the ingress protection code rating, in the case of the immersion ingress protection testing, would always be a 7 or an 8. Below is a brief description of the two types of immersion tests included in ingress protection testing per the IEC test standard. Immersion testing has always been important, but it has become a key marketing point for many manufacturers over the last couple of years.
