What are the general waterproof levels?

What are the general waterproof levels?

19 Aug, 2022

With the improvement of the quality of life, the outdoor activities of modern people are becoming more and more abundant, and the requirements for strong light flashlights are also constantly increasing, especially the outdoor environment and weather conditions are unpredictable, and the waterproof ability of the flashlight is very important for the safe operation and life of the flashlight. It is very important, so everyone should also take the waterproof ability into consideration when choosing a torch.

So about the waterproof level of the flashlight, the questions of many small partners are mainly these questions:

What does the waterproof rating of the flashlight product mean?

What is the waterproof level of the flashlight?

What standard does the waterproof level of the flashlight need to meet?

Does the 8 in IPX8 represent the highest waterproof rating?

The IP (INGRESS PROTECTION) protection level system is drafted by IEC (INTERNATIONAL ELECTROTECHNICALCOMMISSION), which classifies electrical appliances according to their dust-proof and moisture-proof characteristics. The foreign objects referred to here include tools, and human fingers should not touch the live parts of the electrical appliance to avoid electric shock. The IP protection level is composed of two numbers. The first number represents the level of the electrical appliance against dust and foreign object intrusion. The second number represents the degree of airtightness of the electrical appliance against moisture and water intrusion. The larger the number, the higher the protection level. high.

The EN60529 standard is widely used internationally to define the sealing performance of electrical equipment such as inkjet printers. The different categories of protection levels that this standard will quantify mainly include protection against solid foreign objects entering the enclosure (including tools, fingers, or dust, etc.) and protection against water (water entering the enclosure by condensation, flushing, immersion, etc.) influences).

The two digits after the IP indicate the protection strength of the device enclosure against solid foreign objects and water intrusion. The first number indicates the level of the electrical equipment against dust and foreign object intrusion. The highest level is 6; the second number indicates that the equipment is moisture-proof. The degree of airtightness and waterproof intrusion, the larger the number, the higher the protection level, the highest level is 8.

For example IP54 protection grade, IP is the marked letter, the number 5 is the first marked number, and 4 is the second marked number. The first marked number indicates the level of contact protection and foreign object protection, and the second marked number indicates the waterproof protection level.

In addition, when the level of protection requirements is higher than the level indicated by the above characteristic numbers, the extended range will be expressed by adding an appendix letter after the first 2 digits, which also needs to meet the respective requirements of these additional letters.

First of all, let's understand what the two letters of IP mean. The full name of IP is "International Protection Marking", which can also be called protection level or IP code. Common in electronic product parameters, I also call it "waterproof grade", "dustproof grade" and so on. Its definition is the degree of protection against the intrusion of solid and liquid substances that can be provided for electronic products and mechanical equipment.

For example, in the IP67 protection level, the first number "6" represents the dustproof index, and the second number "7" represents the waterproof level. We will mention how much protection "6" and "7" can protect below, but the numbers The larger the value, the higher the protection function of the product, (dust-proof grade 0-6, waterproof grade 0-9).

Sometimes what we see is not the first two letters "IP", but "IPX", and this "X" means that the product has no dustproof function, so it is displayed like this, which is also equal to "0". In addition, there are also cases where two sets of numbers such as "IP65/68" appear on mobile phones or Bluetooth headsets at the same time. The first two "6" are the same dustproof level, which we can easily understand, but why are there two different numbers "5" and "8"? It turns out that their USB charging ports and headphone jacks are not designed with waterproof covers and do not support low-voltage jet protection. The latter "IP68" means that they can be immersed in water for 1m, so there are two sets of numbers

Numbers Protection range
0 Unprotected
No special protection against water or moisture
1 Prevent water droplets from immersing in
Water droplets falling vertically (such as condensation) will not damage the appliance
2 Even when tilted at 15 degrees, it is still protected from water droplets
When the appliance is tilted from vertical to 15 degrees, dripping water will not cause damage to the appliance.
3 Prevents immersion of sprayed water
Rainproof or prevent the water sprayed in the direction with an angle of fewer than 60 degrees from the vertical from invading the electrical appliance and causing damage.
4 Protection against splashing water
Prevent water splashing from all directions from invading the appliance and causing damage
5 Protection against immersion of water jets
Prevent water from entering the appliance from all directions from the nozzle and causing damage.
6 Prevent big waves from immersing in
Electrical appliances are installed on the deck to prevent damage caused by the intrusion of large waves.
7 Prevent water immersion during immersion
The top is 0.15-1 meters away from the water surface for 30 minutes, the performance is not affected, and there is no water leakage; in short, the strong light flashlight can withstand the pressure of water depth within 1 meter when it is fully tightened and closed and can be picked up within 30 minutes. Normal use.
8 Prevent the immersion of water when sinking
The top is 1.5-2 meters away from the water surface for 30 consecutive minutes, the performance is not affected, and there is no water leakage; that is, the water depth is within 2 meters, and the flashlight can be used normally when it is picked up within 30 minutes.

Generally speaking, it is enough for outdoor equipment to reach IPX-7 level, and most of Ao Lei's LED strong light flashlights have reached the waterproof level of eight, even in harsh environments. Full of security!
