In the following waterproof levels, the X in front of the number represents the protection of the walkie talkie against fixed objects, commonly known as the “dustproof” ability. We will only discuss the waterproof level here.
What does IP mean? IP is not the IP address for your computer to access the internet, nor does it refer to intellectual property.
IP stands for Ingress Protection, and the IP protection level system was drafted by IEC (International Electronic Communication) to classify electrical appliances based on their dust and moisture resistance characteristics.
(1) Water droplets are not bad “- IPX1, vertically falling water droplets (such as condensed water) will not cause damage to the walkie talkie.
If you don’t even have this, it means you don’t have any waterproof ability. From the experimental method, it can be seen that this level of protection capability has little significance.
(2) ‘Slant dripping does not damage’ – IPX2, when the walkie talkie is tilted from vertical to 15 degrees, dripping water will not cause damage to the walkie talkie.
The waterproof ability of this level is limited to “water droplet” protection, but it is obviously more practical.
(3) Watering won’t damage “- IPX 3, water sprayed in directions with a vertical angle less than 60 degrees will not damage the walkie talkie.
(4) Splashing water doesn’t damage “- IPX 4, water splashing from all directions can enter the walkie talkie without damaging it.
The waterproof ability of IPX3 and IPX4 is more practical compared to the first two levels. If you want your walkie talkie to have some waterproof ability, IPX3 and IPX4 should be the minimum requirements.
(5) Water spray does not damage “- IPX5, water sprayed from various directions through nozzles can enter the walkie talkie without damaging it.
The water spray rate in the experiment reached 12.5L/min, with a minimum of 3 minutes.
Don’t complain about the small amount of water or the short duration. I believe many intercoms cannot withstand the 12.5 liters of water spray per minute. Being able to achieve this level of waterproofing is also considered a good walkie talkie!
(6) Strong spraying does not damage “- IPX6, preventing damage caused by large waves. This requirement is not low.
The water flow rate is 100L/min, with a minimum of 3 minutes.
This water is cool! 100 liters per minute! You can try taking it under the shower head in the bathhouse.
(7) Short term immersion does not damage “- IPX7, immersing in water for a certain period of time or water pressure below a certain standard can ensure that no damage is caused by immersion.
Place the device in the immersion tank, with a immersion depth of at least 1m from the bottom of the sample to the water surface and 0.15m from the top of the sample to the water surface. The test time is 30 minutes.
Wow, this experiment is a bit interesting. Put the walkie talkie in water for 30 minutes and it can still be used when taken out. Hurry up and see if your walkie talkie can do it! (If there is a problem, the editor is not responsible!)
(8) Continuous diving is not bad “- IPX8, walkie talkies with this ability can be called submarines among walkie talkies!
However, there is no standard for this level of testing, and the testing conditions and time are agreed upon by the supply and demand (buyer and seller) parties. Its severity is generally much higher than IPX7. Top of the line maritime intercoms may have this level of protection capability.
