We have observed a concern during our recent Epoxy ESD floor testing. When we move the test blocks by even a few inches, the resistance readings change significantly (in some cases, go out of specification), where the readings shift from within the acceptable range (10⁵ ohms) to above 10⁹ ohms after repositioning the probes slightly. Could you please confirm if this type of behavior is normal for this flooring system? What might be causing such drastic variation over a small distance?
Should be consider Average to verify the conformance or individual reading should pass the test?
We are also noticing some physical holes on the floor surface. There are small holes forming in certain areas, along with visible bubbles on the surface… I have attached some pictures for your reference. What could be causing these bubbles and surface holes? Are these considered normal ?
