IEC 60060-1:2010

Overview

IEC 60060-1:2010 is an international standard published by the International Electrotechnical Commission (IEC) focusing on high-voltage test techniques. Specifically, Part 1 covers general definitions and test requirements related to dielectric testing using alternating, direct, impulse, and combined voltages. This standard applies to electrical equipment with system voltages over 1 kV, ensuring the reliability and safety of high-voltage apparatus by defining test methodologies to evaluate insulation performance.

The 2010 edition (Edition 3.0) supersedes the previous 1989 version. Key revisions include removal of artificial pollution test procedures (now covered under IEC 60507), transfer of impulse current measurement techniques to IEC 62475, and expression of atmospheric correction factors in formula form to improve test accuracy and consistency.

This standard forms the basis for the consistent evaluation of insulation and withstand capabilities, helping manufacturers and testing laboratories comply with unified global voltage test requirements.
