Does anyone know why this test has not been adopted as a standard to check wiring for new installation?

One of the substantial benefits of this test is that it verifies the integrity of the EGC, its confirms the installation is code complaint.

Of course you have no info at all to show a need for this other than testing gives you the warm fuzzies.
Impedance matters a great deal! High impedance in a AC circuit causes over heating and can lead to fires. This is usually the result of poor connections in switch boxes or loose wiring at receptacle outlet.
I do: Code mandates a new system to be free of defect. How do you know its not? Where is the proof?
That is not proof there is a need
110.7 does not require a test, if you feel it should put in a proposal.
Keep in mind it has been missing EGCs that have been behind most GFCI mandates in the code.

Yes, missing EGCs of appliances, you know those things that get damaged well after the installer has complied with 110.7.

It would add a lot of unnecessary costs to both the EC and the inspection department. Permit fees would have to increase by a substantial amount to cover the costs of the inspector being there to witness the tests. If he is not there, many would just fill out a test report without doing the tests.
I really don't see a need for this. Very few of the so called "fires of electrical origin" occur in dwelling units that are less than 20 years old.
Do you have any statistics or evidence:
1) That new, unmolested wiring is causing fires?
2) That these fires are caused by high impedance connections?
3) That requiring this loop impeadance test would reduce fires?
E= IXR should be proof enough
E= IXR should be proof enough
