C Marking on Sartorius Equipment
In 1985, the Council of the European 
Community approved a resolution 
concerning a new approach to the technical
harmonization and standardization of
national regulations. The organization for
monitoring compliance with the directives
and standards concerning the C marking
is governed in the individual EU Member
States through the implementation of the
EC Directives adopted by the respective
national laws. As of December 1993, the
scope of validity for all EC Directives has
been extended to the Member States of 
the European Union and the Signatories of
the Agreement on the European Economic
Area.
Sartorius complies with the EC Directives
and European Standards in order to supply
its customers with weighing instruments
and related equipment that feature the 
latest technology and provide many years
of trouble-free service.
The C marking may be affixed only to
weighing instruments and associated
equipment that comply with the following
Directives:
