IP Certification that comes with Modern Smartphones
Hitherto, IP certification is a critical and essential subroutine for any manufacturer of smartphone devices. IP Code, International Protection Marking interpreted as Ingress Protection is a standard responsible for monitoring, rating and classification of the level and degree of protection provided to the device against intrusion, dust, accidental handling, and water. An IP rating of a particular device is equated to represent and measure a smartphones level of resistance to particles of dust, water, and many more.
IMPORTANT: Connectors may be susceptible to Ingress of foreign materials such as moisture or dust, particularly unmated condition. Protection for this ingress is provided for by their housing and the seal between the plug, jack, and cable or between a jack and panel.
IP Certification Explained
The IP standard IEC 60529 is tasked to specify the degree of protection defined by the IP number. Companies tasked with the manufacture and assembly of smartphones decide in which environmental conditions can a smartphone survive and then International Electro technical Commission (IEC) rates the device according to their standards. You all must have heard, in any of the smartphone’s specifications, IPXX ratings. On numerous occasions, we have come across alpha-numeric ratings such as IP67 or IP68 but without pretention little or nothing is understood of the code. Technically, let it not be confused to the common IP addressing structural presentation. They are far much a mismatch.
What does the combination of the 2 digits mean?
As we dig deep into the fuss I will delve into the unmasking of the mystery and criterion assumed towards reserving this code structure. My explanation and discussion will be specific to the figure that comes with the modern smartphone devices. The IP code is a pretty logical figure made up of the letters I & P preceded by a combination of two digits. But what exactly does each representation stand for? The first one shows endurance level against solids while the second one shows the endurance level against liquids. So, if the IP rating of an electronic device is high, it means that it has more power to resist any kind of harsh environments including water and dust.
First Digit IPXY (Intrusion Protection)
Dust resistance is normally measured on a scale of 0 to 6. 0 offers no protection, to 5 and 6 offering levels of protection from contact with harmful dust. Best for our knowledge, let’s list the degrees of dust resistance based on the IP Certification:
|0||No Protection against contact and Ingress of objects|
|1||Protected against any large surface of the body, such as the back of a hand. Objects larger than 50mm in size|
|2||Protected against access to hazardous parts by a finger or similar object. Objects greater than 12.5mm in size.|
|3||Objects greater than 2.5mm in size|
|4||Objects greater than 1mm in size|
Second Digit IPXY (Moisture Protection)
Get rid of the myth – no smartphone is completely waterproof, as already stated. There is always a limit to the extent to which a device can be waterproof. How? Well, the second digit in the IP rating provides the extent to which the device could be waterproof. A scale of 0 to 8 is used with 0 offering no protection against water. Pressure plays a critical role in arriving every bit of this rating. Best Advice! Follow your manufacturer’s instruction and advice with regards to the level of your device’s resistance.
|1||Protection against water drops|
|2||Protection against Water drops at 15 Degree angle|
|3||Protection against Water spray at 60-degree angle|
|4||Protection against water splashing from any angle|
|5||Protection against water jets from any angle|
|6||Protection against powerful water jets and heavy seas|
|7||Protection against effects of temporary submersion in water. 30 minutes at 1-meter depth.|
|8||Protection against effects of temporary submersion.|
|9k||Protects against high pressures associated with steam cleaning.|
What is IP67 vs IP68?What is the difference between IP67 and IP68?
Most of the new smartphones come with either of the ratings. The Google Pixel and the iPhone 8 are IP67 certified whereas the Samsung Galaxy S8 and Samsung Galaxy Note 8 got an IP rating of IP68. What does this mean? What extra protection do the Samsung phones offer over the Google Pixel and iPhone 8?
All the smartphones mentioned above comes with the same rating for dust i.e. IP67 which is the highest rating any device can get. IP67 means that the device is fully dust-proof and no dust will enter its body. The second number mostly differs in modern smartphone. The rating of 7 means the device is capable of handling water up to 1m deep for 30 minutes whereas the rating of 8 means the device is capable of handling water up to 1.5m deep for 30 minutes.
This discussion gives the leeway to conclude that you are now knowledgeable of IP ratings. However, high IP certification ratings don’t necessarily imply that dust, water, or debris won’t enter a phone’s enclosure. It indicates that when dust and water do make its way through a phone’s seams, it won’t enter in sufficient quantities to cause malfunction. It’s commendable, the higher the better.
