IEC 60060-1 is a standard that specifies the requirements for the measurement of high-voltage impulses, including lightning impulses and switching impulses. The standard provides guidelines for the calibration of high-voltage measuring systems, including the measurement of peak values, front times, and tail times. IEC 60060-1 is widely used in various industries, including power generation, transmission, and distribution, as well as in research and development.
Dielectric breakdown voltage is heavily influenced by environmental factors such as air density and humidity. Because test laboratories operate at different altitudes and in various climates, IEC 60060-1 provides mathematical formulas to normalize test data to reference atmospheric conditions: 20∘C20 raised to the composed with power C Standard Pressure ( ): Standard Absolute Humidity ( ):

Adhering to IEC 60060-1 is vital for manufacturers and operators of transformers, switchgear, and insulators to guarantee equipment reliability. Mismatches between standards (e.g., using an IEC-rated device in an IEEE-governed grid) can lead to and expensive project delays.
To ensure compliance with global engineering audits and safety regulations, laboratories must obtain legitimate copies of the document. Authorized versions can be purchased and downloaded in PDF format directly from the , the American National Standards Institute (ANSI) store, or other national standards bodies (such as BSI, DIN, or AFNOR). Using official, up-to-date editions guarantees that calculations, tolerances, and waveform parameters align precisely with modern grid expectations.

The IEC TC 42 (High-voltage testing) committee periodically revises standards. While Edition 3.0 (2010) + AMD1 (2021) is current, future revisions may address:
Standard terms and definitions used in high-voltage testing.
The IEC 60060-1:2025 standard (fourth edition) establishes updated international requirements for high-voltage dielectric testing of equipment exceeding 1.0 kV AC and 1.5 kV DC. Key revisions include updated impulse waveform definitions, notably a 170/2,500 µs switching impulse, and enhanced guidance on atmospheric corrections.
