Reference boundary

Insulation-resistance interpretation source-navigation only; no insulation-resistance pass/fail threshold, test-voltage value, procedure step, result interpretation, equipment acceptance criterion, maintenance limit, standards text, acceptance table, or inspection decision is published.

Reference table

Point to public source pages relevant to insulation-resistance result interpretation review.

Reference basis uses test instrument manufacturer navigation, equipment manufacturer source navigation, and maintenance-standard source-owner navigation.
