It is required in many product standards that the protective covers of electrical and electronic devices have a certain level of protection against water and dust. These protection levels are defined by the IP code (Ingress Protection Rating). These codes are determined in accordance with the intended use and purpose of the electrical and electronic devices. In this context, authorized test and inspection organizations test whether the products have the desired IP protection level. The IP protection tests are carried out for all protection levels of electrical and electronic devices in the dust enclosure, which is established in accordance with all the requirements of the standards developed by domestic and foreign organizations. Water or liquid tightness tests of these devices, with the help of a device installed in a special room, vertically flowing drops of water from the hose to pressurized water applications are suitable for many different tests.
The protection levels used in IP protection tests are as follows:
Protection against solid objects
Protection against liquids
Protection from mechanical influences (this protection is not used in the IEC 60529 standard too much)
While protection levels are expressed, each step shows the degree of protection against a separate effect and the numbers in the digits indicate the degree of protection. For example, at the IP66 protection level, the first 6 number indicates that the protection is against solids and is dust-proof, while the second 6 represents protection against liquids and the level of protection against strong spillage. The IP protection levels are determined in two ways: against solids and against liquids.
The need for IP protection tests has arisen because it is desirable to have a certain level of protection against dust and water in the many electrical devices and housings used today. Protection levels vary more depending on where these products are used and the areas of use.
our organization, IP protection test work, With a strong staff and technical infrastructure, in accordance with the relevant legal regulations, standards and test methods published by domestic and foreign organizations. A few standards considered in this context are:
- TS EN 60529 / A2 The degree of protection provided by enclosures (IP code)
- TS 3033 EN 60529 The degree of protection provided by enclosures (IP code) (in electrical equipment)
PROTECTION AGAINST SOLID BODIES
1. Protection against solids with a diameter of 50 mm (5 cm): Protection against access to dangerous parts outside of the hand, a thick pipe, stick ... and objects of this thickness. IP Protection Class
2. Protection against solids with a diameter of 12,5 mm: Finger protection against hazardous areas, back of pen ... and protection against access of objects of this thickness.
3. Protection against solids with a diameter of 2,5 mm: Screwdriver to hazardous parts, male end of an average cable ... and protection against access of objects of this thickness.IP Degree of Protection
4. Protection against solids with a diameter of 1 mm: Wire, pencil tip ... and access to objects of approx.
5. Protection against dust: Reducing the ingress of dust into hazardous areas to levels that will not damage it.
6. Dustproof: Dust ingress is completely prevented.
PROTECTION AGAINST FLUIDS
1. Protection against vertically falling water droplets: Protection against water dripping from the ceiling or other place perpendicular to the device.
2. Enclosure protection against water drops falling obliquely up to 15 °: Protection against rain and the like in windy weather. IP protection class against water
3. Protection against water spray: Protection against water coming from the sprinkler, the fire alarm water, or the angle of incidence.
4. Splash protection: Protection against water splashing from the ground, dripping from the ceiling, coming from the wind ... splashing from all directions.
5. Protection against water spray: Protection against pressurized water such as water from the hose.
6. Protection against strong water flushing: Fire hose and protection against pressurized water of this severity.
7. Resistance to immersion in water less than 30 min: Protection against falling into water, short-term flooding.
8. Protection against the effects of continuous immersion in water: long-term ability to work in water.
Since the IP codes are usually 2 digits, if we examine the 2 digits with an example: IP66
1. protection against solid objects from '6'
2. From the '6' step, we understand that the protection against liquids is at the level of protection against strong water jets.
