The IEC sometimes allows a free preview of the scope, table of contents, and definitions on their website, though the full technical body requires purchase.
Engineers often download a "free IEC 60060-1 PDF" only to encounter serious problems:
| Misconception | Correction from IEC 60060-1 | |---------------|-------------------------------| | “Lightning impulse tolerances are strict” | ±30% on front time and ±20% on tail is allowed. | | “Peak voltage must be exactly √2 × RMS” | Only for pure sine waves; distortion up to 5% allowed. | | “All tests need atmospheric correction” | Correction required for air-insulated apparatus only. |
