IEC 60060-1, titled "High-Voltage Test Techniques – Part 1: General Terminology and Test Requirements," is the definitive international standard for testing electrical equipment designed to operate above 1 kV AC or 1.5 kV DC. It establishes uniform procedures for dielectric tests to ensure that high-voltage (HV) insulation systems can withstand the electrical stresses they will encounter during service.

The latest edition is IEC 60060-1:2025 (Edition 4.0), which was published on April 17, 2025, and replaces the 2010 version. Scope and Applicability

The standard applies to various types of dielectric tests on electrical apparatus, components, or systems, specifically: Voltage Levels: Equipment with highest system voltages ( Umcap U sub m ) exceeding 1.0 kV for AC and 1.5 kV for DC. Test Types: Direct Voltage (DC) tests. Alternating Voltage (AC) tests. Impulse Voltage tests (Lightning and Switching impulses). Combined and Composite voltage tests. Key Technical Components

The document outlines fundamental concepts and rigorous technical criteria for generating and measuring test voltages:

Impulse Waveforms: Defines standard parameters for lightning impulses (typically ) and switching impulses (now standardized at in the 2025 edition).

Atmospheric Corrections: Provides specific formulas to adjust test results based on environmental factors like humidity, temperature (standardized at 20∘C20 raised to the composed with power C ), and air pressure to ensure reproducibility.

Withstand and Disruptive Discharge: Specifies procedures for verifying if insulation can hold a rated voltage (withstand) or at what point it fails (disruptive discharge).

Calculation Annexes: Includes normative procedures for evaluating impulse parameters and a new Annex C in the 2025 edition for manual calculations from graphical waveforms. Significant Changes in the 2025 Edition

Terminology Alignment: Replaced "time-to-peak" with "front time" for switching impulses to match lightning impulse terminology. i--- Iec 60060-1 Pdf

Extended Tolerances: The positive tolerance for the front time of lightning impulses was extended to 100% ( ) for equipment with

  • Acceptable systems: Sphere gaps, voltage dividers (resistive/capacitive), peak voltmeters, digital recorders.
  • Calibration traceable to national standards.
  • Dynamic behavior requirement: Measured voltage deviates ≤ 3% from true value.

10 FAQs About IEC 60060-1 PDF

1. Can I use an older edition of IEC 60060-1?
Only if your contract or internal policy explicitly allows it. Most audits require the current valid edition.

2. Is there a free download of IEC 60060-1 PDF from IEC?
No. The IEC never offers free full-text downloads. They sell PDFs to fund standards development.

3. How many pages is IEC 60060-1?
Approximately 120–150 pages, including annexes.

4. What is the difference between IEC 60060-1 and IEC 60060-2?
Part 1 defines test procedures. Part 2 specifies how to calibrate the measurement systems used in those tests.

5. Can I print the IEC PDF?
Yes, officially purchased PDFs typically allow printing (often with a digital watermark).

6. Is IEC 60060-1 recognized globally?
Yes. It is harmonized with CENELEC (EN 60060-1) and adopted by many countries as national standard.

7. Does it cover partial discharge (PD) tests?
No. PD tests are covered in IEC 60270. But IEC 60060-1 defines the applied voltage for PD tests.

8. What software can open the secured PDF?
Adobe Acrobat Reader works. Some mobile readers may not display digital signatures. Summarize the standard’s scope, main clauses, and key

9. How often is it revised?
Roughly every 8–12 years, with amendments in between.

10. Can I include excerpts from IEC 60060-1 in my internal training?
Yes, under fair use rules for non-commercial internal training, but you must own an original copy.

Key Concepts and Definitions

  • Withstand voltage: the highest voltage that equipment can endure for a specified time without failure. It is used to verify insulation adequacy.
  • Flashover: sudden dielectric breakdown across an insulating surface or through air clearance causing a conductive path.
  • Power‑frequency test: AC testing at nominal or specified test frequency (usually 50/60 Hz) to check insulation under steady oscillatory stress.
  • Impulse test: application of standardized lightning or switching surge waveforms (e.g., 1.2/50 µs for lightning) to assess transient withstand capability.
  • Test levels and test voltages: defined reference voltages for routine, type, and special tests, often depending on equipment rated voltage and installation conditions.

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.
