  • Apply voltage typically at least 10% above the specified test voltage for at least 5 minutes (per older eds — follow 2023 wording).
  • Voltage varied stepwise; measure RI at each step and plot RI vs. applied voltage to determine characteristics and breakdown/flashover behavior.
  • Practical tip: automate voltage stepping and data logging to reduce operator delay and improve resolution of RI curves.

Scope and context

The standard applies to electrical appliances and electric motor-operated apparatus, including: iec 60437 pdf

  • Mounting must simulate service or use standard mounting method specified; include fittings and stress‑control devices when relevant.
  • Earth/ground reference, lead routing, and shielding of equipment are important to avoid spurious pickup.
  • Practical tip: draw and archive a wiring/mounting diagram and take photos—repeatable mounting reduces inter‑lab scatter.
