Electromagnetic compatibility
As from 1 January 1996 all electrical and electronic appliances bearing the CE
marking that are sold on the European market must conform to Directive
89/336/EEC and decree law no. 476/92 concerning electromagnetic compatibility,
i.e. the compatibility of electrical/electronic devices and systems with the
electromagnetic environment in which they are located. The prescriptions regard
two specific aspects in particular:
1. “EMISSIONS: during its operation, the appliance or system must not emit spurious
electromagnetic signals of such magnitude as to contaminate the surrounding
electromagnetic environment beyond clearly prescribed limits”;
2. “IMMUNITY: the appliance or system must be able to operate correctly even when
it is placed in an electromagnetic environment that is contaminated by disturbances
of defined magnitude”.
The following text contains a list of the applied standards and the results of the
electromagnetic compatibility testing of machine model DM 8;
Test report no. 061200.
