IEC 60060-1 provides the foundational language, test definitions, and general requirements essential for consistent, safe, and reproducible high‑voltage dielectric testing across electrical equipment types. Practitioners should use it alongside product‑specific standards to design test programs, interpret results, and certify equipment for field service.
The standard does not just define voltages; it defines the :
IEC 60060-1 is an international standard that defines the general terminology, requirements, and procedures for high-voltage testing of electrical equipment. IEC Webstore The latest version is the fourth edition , published as IEC 60060-1:2025 IEC Webstore Scope and Application

: Applied to evaluate insulation behavior under stable continuous fields.
Mainly used for high-voltage cables and specific apparatus where high capacitance prevents effective AC testing. The standard mandates minimal ripple factors to ensure a stable, near-pure DC electric field during insulation stress analysis. 2. Alternating Voltage (AC) Tests These tests simulate continuous operating frequencies (
Lightning impulses simulate atmospheric discharges. Because lightning strikes happen in microseconds, the standard defines a specific, highly precise wave shape known as the . Front time ( T1cap T sub 1 ): (the time it takes to rise from zero to its peak). Time to half-value ( T2cap T sub 2 ): (the time it takes for the voltage to decay to of its peak value).

Because air density and humidity affect breakdown voltage, the standard provides formulas to correct test voltages to standard atmospheric conditions (101.3 kPa, 20°C, 11 g/m³ absolute humidity).
The IEC 60060-1 PDF outlines several types of dielectric tests, each simulating different operational or environmental stresses: IEC 60060-1:2010
General definitions and test requirements (the focus of this article). 11 g/m³ absolute humidity).
The standard defines how to generate, measure, and evaluate four primary types of dielectric stress:
Used to find the actual breakdown limits of the insulation system.
The standard covers four primary categories of dielectric testing:
