I have been asked by one of my sales men to spec a control system using a "UD 166" standard. Acording to him it is a German Standard. I have done a search nad found nothing relating to this standard. I know Germany follows ATEX standards now. Still curious what UD 166 is suppoed to mean. If anybody can point me in the right direction I would really appricate it.
