Tests of protection provided by enclosures
It is determined the degree of protection provided by enclosures of electrical equipment according to the requirements of standard EN 60529. The relevant degree of protection is stated by IP code in format IPXX.The code consists of two numbers: The first number describes the protection against access to hazardous parts, solid objects and dust and is stated in the range of IP0X-IP6X.
The second number indicates the degree of protection against ingress of water and is stated in the range of IPX0 - IPX9.
