IP rating waterproof test standard for access control
IP grade is to define the dustproof and waterproof performance of the product. The expression method of IP waterproof grade is represented by the letter IP plus two digits. In some cases, letters will also be added (plus letters generally indicate products that can withstand high pressure and high flow). It has a wide range of applications, such as our common electronic waterproof products are only part of it. At present, major mobile phone manufacturers have launched waterproof mobile phones one after another. What is the waterproof performance of IP65 and P67. Understand together.

Representation method: IPXX (IP+dustproof grade number+waterproof grade number)
Dustproof and waterproof performance uses numbers to indicate the degree of protection. Generally, the larger the number, the stronger the protection ability.
Dust level
0 No protection Not protected at all
1 Prevent the intrusion of particles larger than 50mm
2 Prevent the intrusion of objects larger than 12mm This is the lowest level to prevent fingers from entering
3 Prevent all intrusion of objects larger than 2.5mm
4 Prevent the intrusion of objects larger than 1.0mm
5 Dust-proof cannot completely prevent dust intrusion
6 Dust-proof, completely prevent dust intrusion
waterproof level
0 No protection No special protection 1 Prevent dripping Prevent vertical dripping
2 When tilting from the normal position to an angle of 15 degrees, prevent dripping 3 When tilting from the normal position to an angle of 60 degrees, prevent rain and water spray
4 Prevent water splashing from any angle
5 Prevent water from spraying from a 6.3 mm nozzle at 12.5L/min and 30kPa from a distance of three meters for three minutes
6 Prevent water from spraying from a 12.5mm nozzle at 100l/min and 100kPa from a distance of three meters for three minutes
6K prevents water from being sprayed from a 6.3mm nozzle at 75l/min, 1000kPa pressure from a distance of 3 meters for 3 minutes
7 Prevent from intruding into the water 1 meter under normal pressure for 30 minutes
8 Prevent submersion and water intrusion (prevent immersion in one or more deep water under the specifications detailed by the manufacturer)
9K to prevent water pressure from 80-100bar or water temperature 80 degrees Celsius
At present, most products such as (mobile phones, watches, cameras, lamps, etc.) are tested by air-tight leak detectors (also called waterproof testers) for IP level waterproof testing. Compared with traditional water testing, this instrument has fast detection speed, The leakage can be quantified, high accuracy, and no secondary pollution. The only disadvantage is that the leakage cannot be judged. The detection medium of the airtight leak detector is air, which adopts the principle of differential pressure comparison for detection. The principle diagram is as shown in the figure above. This detection method has been widely used in laboratories and online production factories.
