I know this has come up before, but I need to quote chapter and verse. In a conversation with an acquaintance of mine, the EMC Directive became a topic with DoW and use of superceded standards for presumption of conformity becoming a contentious area. I maintain the following understanding:
A product is evaluated to standard A. At some point standard a can no longer be used for presumption of conformity (DoW) and standard B must be used. Therefore if a product is still being manufactured for sale after the DoW of standard A, then the product must be re-evaluated according to the new standard B. (An exemption being those items returned for repair and not modified/updated/upgraded). If the product was no longer produced and placed on the market after the DoW then there is no issue. My acquaintance notes that if the product was tested to standard A, as long as it has not been 'updated, modified, or changed in anyway' since the initial compliance test, it can still be manufactured and placed on the market after the DoW without re-test. I believe that my understanding is the correct one. I tried to locate it in the EMC Directive itself but I can't seem to find it. Am I incorrect? John A. Juhasz GE Interlogix Fiber Options Div.
