IP stands for Ingress Protection. IEC IP protection class is an important indicator for the safety protection of electrical equipment. IP protection class systems provide a classification of the products against the dust, water and collision resistance of electrical equipment and packaging. The method was approved by most European countries, drafted by the International Electrotechnical Commission (IEC) and announced in the IED529 (BS EN 60529:1992) outer packaging protection class (IP code).
The degree of protection is often expressed in IP followed by two digits, and the number is used to define the level of protection.
The first number indicates the range of equipment dust resistance, or the extent to which people are protected from harm in a sealed environment. I stands for the level of preventing the entry of solid foreign bodies, the highest level is 6;
The second number indicates the degree of waterproofing of the device. P stands for the level of preventing water ingress. The highest level is 8.
Such as motor protection class IP65.
