[PSES] AW: [PSES] Safety: 60335-1 conflicting clauses question - earthing (or not) of handles

Hello James, Thank you for providing this additional information and the sketch. My conclusion that the handles are a class II construction was based on your statement in your original post that the handles are not "reliably earthed". As I understand now from your additional information they ar

Re: [PSES] How to Measure Surface Conductivity?

I would measure ohms per square using a milliohm meter. Also, another critical parameter is how hard the coating is. If the new coating is much harder than the original, it will likely make for poorer conductivity at any seams, resulting in lower shielding effectiveness even if the material conduct

Re: [PSES] How to Measure Surface Conductivity?

Try a conductive elastomer on the DMM probes. Intent is to not scratch the surface. However from your description, new coating appears functionally equivalent especially if bonding mechanisms use any type of sharp edge (BeCu gasket, screw, etc)Sent from my mobilePlease excuse brevity & grammar On A

[PSES] How to Measure Surface Conductivity?

I have been given two samples of metal plates; one plated in our current material and the other with a new plating material we want to switch to in production. I have been tasked to compare the electrical surface conductivity. What is the best way to do this? How is this done in the industry? I
