IEC 60034-5-2020 pdf free.Rotating electrical machines – Part 5: Degrees of protection provided by the integral design of rotating electrical machines (IP code) – Classification.
This part of IEC 60034 applies to the classification of degrees of protection provided by enclosures for rotating electrical machines. It defines the requirements for protective enclosures that are in all other respects suitable for their intended use and which, from the point of view of materials and workmanship, ensure that the properties dealt with in this document are maintained under normal conditions of use.
This document does not specify degrees of protection against mechanical damage of the machine, or conditions such as moisture (produced for example by condensation), corrosive dust and vapour, fungus or vermin.
This document is also applicable to explosion proof machines, but it does not specifiy the types of protection for use in a potentially explosive (dust, gas) environment. Those are defined in the IEC 60079 series of standards.
In certain applications (such as agricultural or domestic appliances), more extensive precautions against accidental or deliberate contact may be specified.
This document gives definitions for standard degrees of protection provided by enclosures applicable to rotating electrical machines as regards the:
a) protection of persons against contacts with or approach to live parts and against contact with moving parts (other than smooth rotating shafts and the like) inside the enclosure and protection of the machine against ingress of solid foreign objects;
b) protection of machines against the harmful effects due to ingress of water;
C) protection of machines against the harmful effects due to ingress of dust.
It gives designations for these protective degrees and tests to be performed to check that the machines meet the requirements of this document.
