Typically the default is the light industrial immunity standard EN50082-1 which calls out IEC 1000-4-2 for ESD. Levels can be up to 15kV. Air discharge is used on insulating surfaces such the keyboard, and contact of metal surfaces. In my expereince most testing is done with the air discharge tip. The indirect testing can be troublesome too, especially with cables. We usually test to the highest level 15kV. Particular standards such as medical may change this.
Darrell Locke Advanced Input Devices ---------- From: Biggs, Daniel (IndSys, GEFanuc, NA) To: 'EMC forum' Subject: Operator Interface Displays List-Post: [email protected] Date: Friday, July 30, 1999 7:01AM Does anyone know of a standard that talks about the testing requirements on a display/keyboard interface. I am interested in knowing what kind of ESD tests to perform on it. Are contact, air and indirect discharge necessary? Does anyone have experience with Operator Interfaces? Are there particular levels that they have to meet? DB ___________________________________________________________ Daniel W.
