The standard does not just define voltages; it defines the :

(with recent revisions) is the first part of the International Electrotechnical Commission’s series on "High-voltage test techniques." It is officially titled "General definitions and test requirements." i--- Iec 60060-1 Pdf

This is a foundational international standard used in electrical engineering. If you are drafting a technical paper, a test plan, or a summary based on this standard, it must address the following key areas:

: For switching impulses, the term "time-to-peak" has been replaced with " front time " to match lightning impulse terminology. Standard Switching Impulse : Redefined as 170/2 500 µs . This public link is valid for 7 days

): Adjusts for changes in barometric pressure and ambient temperature. Adjusts for the absolute moisture content in the air. The actual voltage applied during a test (

It defines the ripple factor, which generally must not exceed 3% unless specified otherwise by the relevant product committee. Alternating Voltage (AC) Can’t copy the link right now

) is adjusted based on the standard reference atmosphere (Temperature = 20 °C, Pressure = 101.3 kPa, Absolute Humidity = 11 g/m3g/m cubed ) using the equation: U=U0×Ktcap U equals cap U sub 0 cross cap K sub t U0cap U sub 0

Example: For a medium‑voltage transformer rated 20 kV, IEC 60060-1 supplies the terminology and general test procedures that a transformer standard (e.g., IEC 60076) will reference to specify required power‑frequency and impulse test voltages.
