Equipment classes are defined by Article 4.1 of the Directive. The European Commission has adopted a Decision laying down an initial classification (Commission Decision 2000/299/EC of 6 April 2000).
The decision identifies two classes:
Class 1 equipment is equipment that can be placed on the market and be put into service without restrictions as indicated in Article 1(1) of the Decision. The Commission, in consultation with Member States, publishes an indicative and non exhaustive list of equipment falling within the scope of Class 1:
Class 2 equipment is equipment for which Member States apply restrictions as indicated in Article 1(2) of the Decision, which also assigns the Alert Sign as Equipment Class Identifier for this class.
The following subclasses of Class 2 correspond to radio equipment using harmonised frequency bands for which, in consequence, notification in accordance with Article 6(4) of the Directive is not necessary:
Class 1 and 2 equipment classes can also be searched for in EFIS under documents by selecting frequency range and/or application term.
