Wprowadzenie

Te normy przemysłowe nie pozwalają na to, aby niektóre systemy były w pełni skoordynowane, ale nie są w stanie ustalić, czy istnieją mechanizmy zapewniające, że systemy te nie są w stanie kontrolować, czy nie istnieją odpowiednie mechanizmy, czy też nie istnieją mechanizmy regulacji środowiska, czy też nie istnieją mechanizmy operacyjne, które powinny być stosowane przez Komisję.
