(3) Testing shall be done at temperatures between 600 and 820F. If wiring is tested above 820F, the minimum

acceptable resistance requirement (see table above) shall be reduced by 2 percent for every Fahrenheit

degree above 82'F. If wiring is tested at a temperature below 600F, the minimum acceptable resistance

requirement (see table above) shall be increased by 2 percent for every Fahrenheit degree below 600F.

(4) Allowance should be made to compensate for the electrical characteristics of test instrumentation, including

harnesses.

(5) Reject wiring which does not meet the insulation resistance requirements.
