The DIN 40050-9 standard applies to the IP-protection type of electrical equipment for road vehicles. The standard specifies the marking and definition of IP-protection type and degree of protection established in the road vehicle through the enclosure or enclosure of the electrical equipment. These tags and definitions apply to the following three cases:

First, the protection of electrical equipment, its role is to prevent the intrusion of solid foreign objects (including dust) within the scope of the enclosure (protection of foreign objects);

Second, the protection of electrical equipment, its role is to prevent the penetration of water within the scope of the enclosure (water protection);

Third, the protection of personnel, its main role is to prevent contact between personnel and dangerous parts within the scope of the enclosure (protection of contact);

The requirements for each degree of protection and the tests that must be carried out are also specified in the DIN 40050-9 standard. The purpose of the test is to demonstrate whether the cover meets the relevant protection level requirements.
