UL 60034-5:2019 PDF Download

The UL 60034-5:2019 standard, titled "Rotating Electrical Machines - Part 5: Degrees of Protection Provided by the Integral Design of Rotating Electrical Machines (IP Code) – Classification,” focuses on the classification of degrees of protection provided by enclosures for rotating electrical machines. The standard specifies the requirements for protective enclosures that are suitable for their intended use and maintain their properties under normal conditions of use.

However, it is important to note that this standard does not cover the protection of machines against mechanical damage, conditions such as moisture, corrosive dust and vapor, fungus, vermin, or types of protection for machines used in potentially explosive environments (dust, vapor).

The UL 60034-5 standard also acknowledges that certain applications may require additional precautions against accidental or deliberate contact. It provides definitions for standard degrees of protection applicable to rotating electrical machines, focusing on the protection of persons against contact with live parts, moving parts inside the enclosure, and the ingress of solid foreign objects. Additionally, it addresses the protection of machines against the harmful effects of water ingress.

The standard includes designations for these protective degrees and outlines the tests that need to be performed to ensure that the machines meet the requirements of the standard.
