In an earlier post I already showed you what it is with the Degree of protection IP67 or the term “splash-proof” and what the term “waterproof” is all about. In these entries I also mentioned some IP numbers including a few brief explanations. In the following I would like to give you a small but comprehensive insight into the key figures EN 60529, DIN 40050-9: 1993-05 and ISO 20653: 2013 give.
The combination of letters IP indicates that it is a protection acts in accordance with the above standards and that the following indicators show the degree of protection. The first digit (possibly with additional letters) shows the protection against foreign objects such as dust. The second number (also partly with additional letters) shows the protection against water. Here is a practical table that brings you closer to the IP protection classes at a glance:
|Protection classes according to DIN 40050|
|First digit||Protection against foreign bodies||Second digit||Protection against water|
|0||No protection||0||No protection|
|1||Protection against solid foreign bodies> 50 mm||1||Protection against dripping water|
|2||Protection against solid foreign bodies> 12,5 mm||2||Protection against dripping water including inclination up to 15 °|
|3||Protection against solid foreign bodies> 2,5 mm||3||Protection against spray water including inclination up to 60 °|
|4||Protection against solid foreign bodies> 1 mm||4||Protection against splash water|
|5||Protection against dust||5||Protection against water jets|
|6||dustproof||6||Protection against water jets with increased pressure|
|7||Protection against brief immersion|
|8||Protection against prolonged immersion (possibly with an additional number indicating the maximum depth)|
|9K||Protection against high pressure water jets / steam cleaning|
Especially in industry, the protection classes and their labeling are not only helpful, but essential. Headlights in cars, for example, have to be completely waterproof and somewhat dustproof. Other components in this industry should also not let any water inside. Private users benefit in the same way as with completely different products; one GoPro camera for example, which should be used in dusty off-road terrain and under water alike.
