IP Tests

The EN 60529 standard, designed by the IEC (International Electrotechnical Commission), reflects an international classification system for the sealing strength of electrical equipment enclosures, instruments, dust or foreign objects such as hands and fingers and the penetration of moisture.

This classification system consists of two or three digits followed by the letters IP (ingress protection). Although two numbers are generally used, in some cases the third number also makes sense. If only one protection class is provided for an electrical device, the letter X is used for one of the digits. For example, the coding of IPX4 is only relevant for the moisture resistance of the device.

This standard has also been published in our country by the Turkish Standards Institute with the following title: TS 3033 EN 60529 The degree of protection (IP code) provided by enclosures (in electrical equipment).

The first number of degrees of protection indicates the degree of protection when persons come into contact with moving parts and indicates the degree of protection of the equipment against solid foreign objects entering a housing. Namely,

0 = No special protection

1 = Protection from a part of the body, such as the hand, or solid objects with a diameter greater than 50 mm (but no protection against intentional access)

2 = Protection against fingers or other objects whose length is not more than 80 mm and diameter no more than 12 mm

3 = Protection against tool, wire and similar inlets with a thickness or diameter greater than 2,5 mm

4 = Protection against solid object entries with a thickness or diameter greater than 1 mm

5 = Protection against the amount of dust that may interfere with the operation of the equipment

6 = Dustproof

The second number of degrees of protection shows the degree of protection of the equipment in the enclosure against harmful ingress of various forms of moisture, for example, dripping, spraying, dipping and the like. Namely,

0 = No special protection

1 = Protected against vertically falling drops of water or condensation (protection against dripping water)

2 = Protected against vertical drops of water, if the case is placed from vertical to 15 degrees (protection against vertically dripping water)

3 = Protected against water sprays in any direction from vertical to 60 degrees (protection against sprayed water)

4 = Protected against splash water from any direction (unlimited access) (splash protection)

5 = Protected against low pressure water jets from any direction (limited entry allowed)

6 = Protected against high pressure water jets from all directions (limited access allowed)

7 = Protected against short periods of immersion in water (15 cm to 1 m)

8 = Long-term, long-lasting, water-resistant (under pressure) (more than 1 m)

For example, the IP68K coding is an IP (ingress protection) code, which is prescribed by the German standard DIN 40050 Part9, expressing protection in high temperature and pressurized waters. The first number 6 shows that this product is dustproof and the second number 8 is highly protected against submersion.

IP coding refers to both the protection of electrical devices and the protection of persons using these devices.

Our organization also provides IP (access protection) testing services within the scope of certification services. Thanks to these services, enterprises are able to produce more efficient, high performance and quality products in a safe, fast and uninterrupted manner.

IP (access protection) testing services provided within the scope of certification services are only one of the services provided by our organization in this respect. Many other certification services are also available.
