Why Conventional EMC Testing is Insufficient for Functional Safety

At the recent PSES Sym­posi­um, I atten­ded a couple of inter­est­ing work­shops on EMC and Func­tion­al Safety. One was called “Work­shop on EMC & Func­tion­al Safety” presen­ted by Keith Arm­strong, Bill Radasky and Jacques Delaballe. The oth­er was a paper present­a­tion called “Why Con­ven­tion­al EMC Test­ing is Insuf­fi­cient for Func­tion­al Safety” presen­ted by Keith Armstrong.
