OFFICIAL JOURNAL of the EU extract

• compliance of equipment with the relevant harmonised standards

• conformity with the essential requirements

• compliance of apparatus

• EC declaration of conformity

“Member States are obliged to take the necessary measures to ensure that products are only

placed on the market

or put into service

if they do not endanger the safety and health of persons

or other public interests covered by the Directive,

when properly installed, maintained and used for the intended purposes”

(first time availability)(first time usage)


5

NEED for COMPLIANCE (CONFORMITY)

the chosen route to compliance must provide

sufficient evidence that apparatus (product) in all its foreseeable configurations

meets the ‘essential requirements’

of the New EMC Directive


6

ESSENTIAL PROTECTION REQUIREMENTS

the electromagnetic disturbance generated does not exceed

the level above which other equipment cannot operate as intended

a level of immunity to electromagnetic disturbance

without unacceptable degradation of operation in its intended use
