EMC-pstc-list, I have a question concerning the EMC directive. We are in a situation were an old standard EN 60601-1-2:1993 is superseded by a new one: EN 60601-1-2:2001.
I have a discussion with a colleague about what should happen after the date of withdrawel (DOW). Here is a small part from a text that my colleagues are referring to): When a harmonized standard used for presumption of conformity changes (as a result of a new edition, for example), then the presumption of conformity cannot be continued ad-infinitum by the manufacturer. Until the manufacturer can demonstrate conformity to the newer version of the standard he cannot affix a CE marking to the product or place it on the EU market.. Often this is not well understood. iI fact, many manufacturers think that their product is "grandfathered". The truth is, all devices placed on the market after DOW must meet the new version of the standard if the manufacturer wishes to continue to legally affixing the CE mark. This interpretation differes from my personal view: A product should comply with the essential requirements of the EMC directive, that is, (1) protection of radio-service and (2) immunity with respect to external disturbances. One should use all (applicable) standards to demonstrate the above. If a harmonized standard changes, for example a new edition, then it is not necessary ilegal to affix the CE label and place the equipment on the EU market. We have already demonstrated that it meets the essential requirments of the EMC directive. Of course, when there is a technical change in the standard then a (risk) analysis should be done to assess the effect on the EMC performance and, possibly, action is required on behalf of the manufacturer. So all devices placed on the market after the DOW do not necessarily have to meet the new standard. And in theory it is possible that products are indeed "grandfathered" This probably an old topic. (???)
