In IP65 Waterproof Rating, first digit 6 means that the device is fully dustproof and no solid object can go inside and damage it while the second digit 5 means device can resist low-pressure water from any angle.

IP65 Rating Test Method
Any device which is tested for waterproof and assigned IP65 Rating passes through this test.
As such device is claimed to resist low-pressure water, so for test purposes, water is thrown over it at the rate of 12.5 liters per minute at a pressure of 30 kPa from a distance of 3 meters.
If a device passes this test, the second digit is given value “5”. For solid particles, it is tested separately and if no dust enters the device, it is given maximum value of “6” to the first digit.
To verify whether your device is really IP65 Rated or not, you can perform the test yourself. But keep in mind, you did it right by having all the necessary equipment.
Where we need devices with IP65 Ratings?
It is one of the most important questions if you really need an IP65 Rating or not. These devices are fully dustproof. You can use them in a place where is too much dirt. So, if you live in such a place or hope to go there, you must go for fully dustproof devices. Otherwise, there is not a bigger need for any device to be dustproof.
IP65 means low resistance to water. These devices are not fully waterproof but can bear low-pressure water such as rain etc. It is not possible to submerge them in water even for a little time as there is a risk of losing the product. If you are planning to use these devices in areas, where they can sometimes be submerged in water, go for high ratings.
In short, all devices with IP65 Rating are water-resistant but not waterproof and fully dustproof.
