Note: Rubber linings will not be damaged by spark testers when calibrated and properly maintained. Tests by researchers at Northwestern University as well as The Chlorine Institute found that normal usage of spark testers on 1/8 inch and thicker rubber sheets does not cause dielectric breakdown (Bailey,2008). The probe shape is very important.
