Are machines with the CE mark certified?
The CE mark was a good concept in its inception but this has been so much abused which has become practically meaningless for the end user. It is not a certification or a quality mark, furthermore is not granted by any controlled or official body in any way, distributors or end users have no right whatever to demand a CE certificate by the manufacturer, even though his products bear the stamp.
Declaration of CE from the manufacturer stating the object complies along with CE regulations and directives. Really is the equal to taking the words of a used car salesman as Gospel truth. The market is awash along with shoddy products of uncertain basis and parentage bearing the CE mark, products which, obviously, do not be conventional to any regulation whatever.
Within a resume: the CE mark does not attest or imply any fitness or quality for use of the object t bearing the stamp. This only says that the manufacturer declares as his product is built in as per with the community directives, in his own responsibility and without effectual control by an official body.
