The requirements specified by directive 89/336/EEC are as follows. CE compliance requires
that the manufacturer or its authorized representative established within the Community affix
the EC conformity mark to the apparatus or else to the packaging, instructions for use, or
guarantee certificate. The EC conformity mark shall consist of the letters CE as specified and
the figures of the year in which the mark was affixed. This mark should, where appropriate, be
accompanied by the distinctive letters used by the notified body issuing the EC type-
examination certificate. Where the apparatus is the subject of other Directives providing for the
EC conformity mark, the affixing of the EC mark shall also indicate conformity with the relevant
requirements of those other Directives.
