Susan, I'm not sure what "AC" means in your message below. I'm assuming that you mean in the radio frequency range, where low bonding impedance across joints means good shielding effectiveness.
There is an SAE standard for measuring the "transfer impedance" across EMI shielding gaskets: SAE-ARP-1705. I personally have never seen the actual standard. I have only seen it quoted as a reference document on spec sheets for EMC gaskets. Is this the type of information that you're looking for? Perhaps those more familiar can comment? If you are dealing with lower frequency "AC" such as 60Hz, 1Khz... I have already seen some replies that provide some decent guidance on how to perform this measurement.
