Reference boundary

Insulation-resistance test-voltage source-navigation only. It does not publish insulation-resistance test voltage values, acceptance thresholds, pass/fail criteria, procedure steps, equipment lists, or compliance decisions.

Reference table

Point to public source pages relevant to insulation-resistance test-voltage review.

Reference basis uses manufacturer test-instrument guidance, asset manufacturer instruction navigation, and standards source-owner navigation.
