What Is an IP Code?The Electro Technical Commission started the Ingress Protection rating or International Protection Marking, otherwise known as IP, to rate the protection given to electrical parts. Specifically, the ratings help identify how well electronics and parts are protected against different types of intrusion or immersion in water.
The IP code is two digits and applies to all types of electrical devices, including smartphones and tablets. The first number represents the durability against solid objects and the second by water. So, if the first number is zero (or marked with an X), it has no protection against solid objects. If the second number is four, this means it is protected against objects that are bigger than 2.5 mm, such as wires.
How Does IP Benefit the Customer?Without an IP code standard, manufacturers potentially could claim any device is waterproof without much accountability for it. The IP code helps standardize what to expect from manufacturer claims. You may never actually check to see what the code is, but the manufacturer must create their product according to standard to secure the rating they want. This can prove challenging depending on the product, but it helps deliver reliable products to the public.
How Do IP Codes Affect Smartphones?As smartphones evolve, so do their IP codes and manufacturing standards. Currently, there are dozens of waterproof and even self-healing smartphones on the market. For example, the Sony Xperia Z3 claims a slim, waterproof design. But what does that really mean?
The Sony Xperia Z offers a rating of IP55 and IP58 for dust and water, respectively, reports Phone Cruncher. More specifically, this means the device is protected against low-pressure jets or rain. However, it also can be kept in 1.5 meters of fresh water for up to half an hour at a time, which makes it compliant with the rating IP 58.
