Iec 6193612021 - Link [2021]
The standard refines the calculation of minimum air clearances. It emphasizes the relationship between the and the Rated Power Frequency Withstand Voltage . The 2021 edition provides updated tables for phase-to-earth, phase-to-phase, and phase-to-structure clearances, ensuring designs can withstand transient overvoltages more effectively.
If you previously used the 2010 or 2015 versions, note:
Understanding what the standard covers—and what it explicitly does cover—is critical for correct application.
IEC 61936-1:2021 often calls up:
| National Representative | Country/Region | |---|---| | | Canada | | NBN | Belgium | | BSI | United Kingdom | | EVS | Estonia | | NSAI | Ireland | | AFNOR | France | | DIN | Germany | | JSA | Japan |
The provisions of IEC 61936-1:2021 explicitly cover the following installations:
For engineers and project managers, compliance with this standard is not merely a regulatory hurdle but a fundamental engineering practice to mitigate risk, ensure longevity of assets, and protect human life. iec 6193612021 link

The first edition of IEC 61936‑1 was published in . A second edition followed in 2010 , with an amendment in 2014 . The third edition (2021) therefore represents more than a decade of accumulated experience and technical progress.
A major focus of the standard is maintaining safe distances to prevent accidents. The standard refines the calculation of minimum air
