IP67, IP68, and now even IP69K: What these cryptic codes imply? And what do they imply when explaining a smartphone safety ranking? Hold studying to learn the way your telephone (or different system) is protected towards water and/or mud.
As soon as unique to rugged telephones, IP certification might be discovered on most flagship telephones, and even some mid-range fashions right now. The title refers to “Ingress Protection”, and defines how a tool is protected towards water and mud.

The IP certification is outlined by various requirements, beginning with IEC 60529, with additional extensions focusing on particular use instances that had been later included into the IEC (Worldwide Electrotechnical Fee) commonplace. One such instance is the IPx9 (or IPx9K) ranking for warm, high-pressure water jets, initially designed for autos needing high-pressure cleansing.
The IEC 60529 commonplace specifies not solely the necessities for every safety ranking but in addition the required testing procedures. It is very important observe that the IP ranking is self-reported and (at the least within the case of mobiles) not verified by impartial testing businesses.
The IP code has two numerical digits, the primary one signifies the extent of safety towards strong objects—e.g. mud—whereas the second signifies the safety degree towards water. In each instances, increased numbers signify higher safety.
First digit of the IP ranking
First digit
Which means
X

0
No safety
1
Safety towards strong objects measuring as much as 50 mm³
2
Safety towards strong our bodies measuring as much as 12 mm³
3
Safety towards strong objects measuring as much as 2.5 mm³
4
Safety towards strong objects measuring as much as 1 mm³
5
Safety towards mud, restricted ingress of mud (posing no threat to the system)
6
Full safety towards mud
Second digit of the IP ranking
Second digit
Which means
X

0
No safety
1
Safety towards vertically dripping water (condensation)
2
Safety towards water spray when vertically tilted at 15°
3
Safety towards water projections at any vertical angle as much as 60°
4
Safety towards water projections from all instructions – minor ingress
5
Safety towards jets of water from all instructions – minor ingress
6
Safety towards slight jets of water, restricted ingress (below the casing, for instance)
7
Safety towards results from immersion in liquids between 15 cm and 1 m (3 ft 3 in) in depth
8
Safety towards lengthy immersion durations and water stress
9
Safety towards pressured high-temperature water jets
Word: IP69 was initially outlined as “IP69K” by the ISO 20653 and DIN 40050-9 requirements, and is roughly the identical within the IEC 60529 ranking system.
One other essential consideration is that the IP ranking is legitimate just for the unique design. Any sort of change to the telephone physique, together with unintentional drops, can change the safety ranking of the system. Early IP-rated smartphones, notably these from Sony Ericsson, weren’t clear about this, and their fragile design led to some lawsuits.

Now we have come a great distance from the time when solely area of interest telephones—such because the rugged Motorola Defy—had water and mud safety. These days even mid-range telephones are incessantly IP-rated, with most flagships being at the least IP68 rated, and even some foldable telephones having some degree of safety.
What about you? Do you assume water and/or mud resistance is a vital criterion when looking for a telephone? Share your ideas within the feedback beneath. As for me, with a Defy, Xperia Z1c, Galaxy S7+S9, and a few Pixel telephones as every day drivers, it’s fairly clear what my ideas are.
