My Smartphone Has IP67 Rating. What Does That Mean? IP Rating Explained
When you read product specifications, you will often see gadgets being classified according to their IP rating. Some are said to come with IP68 rating, while others sport IP 65. What does that mean exactly? Are the differences between the two significant and should they be affecting your purchase decisions?
Let’s find out.
IP stands for “ingress protection” or “ingress protection” or “index f protection” and basically represents an international standard regarding the level of sealing effectiveness of electrical enclosures against various foreign elements, like dust, dirt, water and others.
The rating is presented as two capital letters “IP” followed by two digits.
The two numbers come with a specific individual meaning.
The first number indicates the degree of protection from moving parts and foreign elements, while the second one refers to protection against moisture. Let’s get into more detail.
First Digit (moving parts and foreign elements)
0 – No ingress protection
1 – Protection against any large surface of a human body, like the palm of the hand (but no protection against deliberate access); protection from solid objects larger than 50 mm in diameter.
2 – Protection from fingers or objects not bigger than 80mm in length and 12 in diameter.
3 – Protection against tools and thick wires (2.5 mm in diameter and more)
4 – Protection against fine tools and objects (larger than 1 mm)
5 – Dust protection (dust ingress is not complete, but it will not enter in sufficient quantity to harm the operation of the device)
6 – Complete dust protection, dust tight.
Second Digit (moisture)
0 – No water protection
1 – Protection against condensation
2 – Protection against vertically dripping water – when the enclosure is tilted 15 degrees form its normal position.
3 – Spray protection (at angels up to 60 degrees)
4 – Protection against water spraying from all directions
5 – Protection against low pressure water jets (for instance, projected from a nozzle)
6 – Protection against strong water jets and waves
7 – Protected against temporary immersion in water for up to 1 mm
8 – Protected against prolonged immersion and pressure (specific conditions should be specified by the manufacturer).
Most rugged products come with the 4 most common IP ratings, those of 65, 66, 67 and 68. If you come across a device with one of these ratings, take a quick look below:
IP 65 – dust tight (complete dust protection), protection against water jets from a nozzle.
IP66 – dust tight, protection against heavy water jets
IP67 – dust tight, immersion-proof
IP68 – dust tight, prolonged immersion-proof
