What is the IP69K LED tri proof light?


September 15, 2018

IP (International Protection Standard) is a term defined by DIN VDE 0470 and DIN 40 050.
These standards give a classification of the degree of protection of electrical equipment enclosures when the rated voltage does not exceed 72.5 KV.

The details are as follows:
1. Personal protection.
2. Protection of electrical equipment to prevent the entry of solid materials including dust.
3. Protection of electrical equipment to prevent damage caused by water to equipment.

An IP code consists of the letters “IP” and two digits. The first digit is 0 to 6, and the second digit is 0 to 9 or 9K:

IP67: Soaking in water from 15 cm to 1 m deep for 30 minutes prevents water from entering.

IP68: Under the conditions specified by the supplier, it is continuously immersed in water to prevent water from entering.

IP69K: Capable of withstanding the thermal steam wash test defined in EN 60529 and DIN 40050-9. This provides protection against water pressures of 100 bar (1450 psi) and temperature of 80oC. The pressure is applied directly to the sensor at progressive angles of 30 degrees (0, 30, 60 and 90 degrees) for 30 seconds at each angle for a total of 120 seconds (2 minutes) to prevent water ingress.
These IP protection levels are often not properly understood or applied incorrectly. For example, many users believe that the IP67 or IP68 protection class allows the device to function properly while the water is within the specified time. This is not the case. These levels of protection only guarantee that the equipment will still function properly after it has been removed from the water.
Another possible misunderstanding is that meeting IP69K means automatically meeting IP67 and IP68. In fact, IP69K can only protect against flushing pressure and is not suitable for applications that are submerged in water. Therefore, the IP69K protection class is often used in applications where cleaning is often performed, such as in breweries, car washes, and food and beverage plants, but is not suitable for use where the equipment is completely submerged in water.
