Dispensing certification?
Should it be required for public charging stations be tested by the departments of weights and measures to verify accurate metering? Wouldn't it be fair since gas stations have to do it?

Only if they're found to be cheating, which seems unlikely since it would be incredibly easy to detect.

Here in Canada our Measurement Canada department is working on exactly that for DC fast chargers. Right now it’s illegal even for utilities that generate the power to sell electricity by the kWh, so chargers are mostly sold by time. That does mean slower charging vehicles pay more.

It depends on how the station is billing. In some places, they can't sell "by kilowatt-hour", because they'd have to register as an electric utility to do that, so they bill per minute.
In others, they do bill by kilowatt-hour, and one would assume that they have to use calibrated systems just like an electric utility does.

you have a meter in your house that measures how much electricity you use. unlike "thumbing the scale at the butcher" - you have unsafe electrical equipment and your house could burn down, or the guy installing it or even using it could get killed.
part of safety is accuracy - do not misreport any amount of juice because of the fire risk.
in order to have a UL listing, all the parts need to be certified before they're installed.

UL, LLC is a global safety certification company headquartered in Northbrook, Illinois. It maintains offices in 46 countries. Established in 1894 as the Underwriters' Electrical Bureau (a bureau of the National Board of Fire Underwriters),[2] it was known throughout the 20th century as Underwriters Laboratories and participated in the safety analysis of many of that century's new technologies.[3]
UL is one of several companies approved to perform safety testing by the U.S. federal agency Occupational Safety and Health Administration (OSHA).[4] OSHA maintains a list of approved testing laboratories, which are known as Nationally Recognized Testing Laboratories.[5]

OP is specifically asking about public charging stations, not home chargers. Having a UL listing or certification also doesn't guarantee accuracy of metering.

No.
Every EV has extremely accurate measuring of what it gets.
If there is a disagreement, investigate.
But there is no need for extra cost, bureaucracy, complication. That is just another effort to slow down EV adoption and charger roll-out. The fossil industry in full FUD mode.
(It was needed for cars that don't have accurate ways to measure how much fuel they get, and the gas stations cheated when they could - they cannot cheat as easily with EV. And worse, everyone can charge at home, so people don't need them anymore, or only in some circumstances)
