    What is IP Testing?

    IEC 60529 describes a system for classifying degrees of protection provided by enclosures. This IP coding defines the extent to which an enclosure provides protection for:

    persons against access to hazardous parts,

    equipment against ingress of solid foreign objects

    equipment against harmful effects due to ingress of water

    The IP code consists of two numerals and may include additional and supplementary letters.

    The first characteristic numeral indicates degree of protection against access to hazardous parts and against solid foreign objects. The second characteristic numeral indicates of protection against ingress of water.
    (*Letter X indicates that characteristic numeral is not required to be specified).
    An overview of the protection codes is given below:
