Most of the time you can find devices with IP65 certified but also sometimes there is a letter at the end.
As I had search often to know what means what I've done now this table here:
| No. | Solids (1st Digit) | Liquids (2nd Digit) |
|---|---|---|
| 0 | no protection | no protection |
| 1 | Protection from objects > 50mm like a hand |
Protection from vertically dripping water |
| 2 | Protection from objects > 12mm like a finger |
Protection from dripping water when tilted to 15° |
| 3 | Protection from objects > 2,5mm like a cable |
Protection from spraying water up to 60° from its normal position |
| 4 | Protection from objects > 1mm like a nail or wire |
Protection from splashing water from any direction |
| 5 | Dust protected resistant to incidental dust |
Protection from water jets from any direction |
| 6 | Dust tight no ingress of dust |
Water resistant against powerful jets |
| 7 | Protection from immersion up to 1m for a limited time |
|
| 8 | Protection from continous immersion beyond 1m |
|
| 9 | Protection from close-range high presure water jets |
Optional letters at the end
| Letter | Meaning |
|---|---|
| D | Wire |
| F | Oil Resistant |
| H | High Voltage Apparatus |
| M | Device is in motion |
| S | Device is standing still |
| W | Certain weather conditions |
