Shanghai Yichuan Instrument Pressure GaugeThe IP protection level system was drafted by IEC (International Electrotechnical Communication). Classify the lighting fixtures according to their dust-proof and moisture-proof characteristics. The external objects referred to here include tools, and human fingers should not come into contact with the live parts inside the lamp to avoid electric shock. The IP protection level is composed of two numbers. The first number represents the level of dust separation and prevention of foreign object intrusion of the lamp, and the second number represents the degree of sealing of the lamp against moisture and water intrusion. The larger the number, the higher the protection level. The two marked numbers represent the protection level as shown in Table 1 and Table 2.
Table 1: Protection level indicated by the first characteristic number (digit) Definition of protection level indicated by the first characteristic number (digit)
There is no protection for people outside or no special protection.
1. Prevent solid objects larger than 50mm from entering and prevent human bodies (such as palms) from accidentally coming into contact with the internal parts of the lamp. Prevent the intrusion of larger objects (diameter greater than 50mm).
2. Prevent solid objects larger than 12mm from entering and prevent human fingers from touching the internal parts of the lamp to prevent medium-sized (diameter greater than 12mm) foreign objects from entering.
3. Prevent solid objects larger than 2.5mm from entering and preventing tools, wires, or similar small foreign objects with a diameter or thickness greater than 2.5mm from entering and coming into contact with the internal parts of the lamp.
4. Prevent solid objects larger than 1.0mm from entering and preventing tools, wires, or similar small foreign objects with a diameter or thickness greater than 1.0mm from entering and coming into contact with the internal parts of the lamp.
5. Dust prevention completely prevents foreign objects from entering. Although it cannot completely prevent dust from entering, the amount of dust that enters will not affect the normal operation of the lamp.
6. Dust prevention completely prevents foreign objects from entering and can completely prevent dust from entering.
Table 2: The protection level indicated by the second characteristic number (number) and the definition of the protection level indicated by the second characteristic number (number)
No protection, no protection.
1. Prevent water droplets from entering vertically dripping water droplets (such as condensed water), which will not have harmful effects on the lamp.
When tilted at 15 degrees, it can still prevent dripping water from entering. When the lamp is tilted from vertical to 15 degrees, dripping water will not have harmful effects on the lamp.
3. Prevent sprayed water from entering the rainproof area, or prevent water sprayed in a direction with an angle less than 60 degrees from entering the lamp and causing damage.
4. Prevent splashing water from entering and prevent splashing water from all directions from entering the lamp and causing damage.
5. Prevent the intrusion of sprayed water and prevent water from nozzles in all directions from entering the lamp and causing damage.
6. Install lighting fixtures on the deck to prevent the intrusion of large waves and prevent damage caused by the intrusion of large waves.
7. To prevent water from entering during immersion, immersing the lamp in water for a certain period of time or keeping the water pressure below a certain standard can ensure that it is not damaged due to water ingress.
8. Prevent water intrusion during sinking. The lamp can sink indefinitely under the specified water pressure, ensuring no damage caused by water ingress.
