The insulation resistance test is an electrical test which uses a certain type and level of voltage 500v d c.
The measured resistance indicates the condition of the insulation between two conductive parts.
The insulation resistance test is the second test required by the electrical safety testing standards.
The results obtained from ir test are not intended to be useful in finding localized defects in the insulation as in a true hipot test but rather give information on the quality of the bulk material used as the insulation.
Insulation resistance test values use these values in the absence of consensus standards dealing with insulation resistance tests.
Test results are dependent on the temperature of the insulating material and the humidity of the surrounding environment at the time of the test.
When performing insulation resistance testing you must maintain consistency.
