What is the degree of IP protection?
The IP degree of protection refers to an international standard that differentiates between the different degrees of protection against the entry of foreign materials or particles (dust, water, etc.) into said materials. The letters IP come to mean the English Ingress Protection
According to this nomenclature, after the acronym IP there are 2 numbers. The one that corresponds to the tens refers to the degree of protection against the entry of solid objects and the digit of the units refers to the degree of protection against the entry of water
In this way, the CEI 60529 standard, which regulates this nomenclature, establishes the following levels for each of the two digits:
- For the 1st or tens digit, the following levels of protection against particles are established:
- 0: No protection
- 1: The element that must be used to the test (50 mm diameter sphere) must not go all the way in.
- 2: The item to be used for the test (12.5 mm diameter sphere) must not go all the way in.
- 3: The element to be used for the test (2.5 mm diameter sphere) must not enter the least.
- 4: The element to be used for the test (1 mm diameter sphere) ) must not enter in the slightest.
- 5: The entry of dust cannot be avoided, but the m The same must not enter in such a quantity that it interferes with the correct operation of the equipment.
- 6: Dust does not enter under any circumstance.
- For the 2nd digit or of the units, the following levels of protection are established against water intrusion:
- 0: Water will enter the equipment in a short time.
- 1: Water should not enter when it is dropped from a height of 200 mm relative to the equipment for 10 minutes (at a rate 3-5 mm³ per minute)
- 2: Water should not enter when it is dropped, for 10 minutes (at a rate of 3-5 mm³ per minute). Said test will be carried out four times at a rate of one for each 15° rotation both vertically and horizontally, starting each time from the normal working position.
- 3: The water mist must not enter at an angle of up to 60 ° to the right and left of the vertical at an average of 11 liters per minute and at a pressure of 80-100 kN/m² for a time not less than 5 minutes.
- 4: Water thrown from any angle at an average of 10 liters per minute and at a pressure of 80-100 kN/m² for a time not less than 5 minutes.
- 5: Water jetted (from any angle) through a 6.3 mm diameter nozzle, at an average rate of 12.5 liters per minute and at a pressure of 30 kN/m², must not enter during a time that is not less than 3 minutes and at a distance of not less than 3 meters.
- 6: Water thrown in jets (from any angle) through a 12.5 mm diameter nozzle must not enter, at an average of 100 liters per minute and at a pressure of 100 kN/m² for no less than 3 minutes and at a distance of no less than 3 meters.
- 7: The object must withstand, without any leakage, complete immersion at 1 meter for 30 minutes without water entering
- 8: The electrical / electronic equipment must withstand (without any leakage) complete and continuous immersion to the depth and for the time specified by the product manufacturer with the agreement of the customer, but whenever conditions more severe than those specified for value 7 result without water entering a.
- 9K: Protected against high-pressure, high-temperature short-range jets
Thus, by way of example, the following standards would mean:
- IP65: Complete protection against dust (6) and water jets (5) not pressure
- IP67: Dustproof (6) and complete immersion in water for no more than 30 minutes (6)
- IP68: Dustproof and complete and continuous immersion in water.
In addition, the Effect of pressure Regarding protection against water, we do not generally speak of depths greater than one meter, so it is advisable to read the specific specifications of the product given by the manufacturer to know the immunity that we really have.
In this section we have grouped only components that have a tightness index or IP degree greater than or equal to IP65.
