Is there a field test to determine if aluminum handrails are anodized?

Use a volt meter the anodized film is not conductive. If it conducts electricity on the voltmeter it is not anodized or you pushed the probes too hard and broke through the anodized layer. You have to push pretty hard to break through the anodized layer.

The easiest way to check for an anodized surface is to use an Ohmmeter. An anodized surface is non-conductive.

A simple, and inexpensive test, would be to take an ohmmeter and test for continuity..as anodizing is a dielectric coating.
