2. ‘new equipment’ means equipment for which, by the cut-off date, neither of the following events has occurred:

(a)signature of the relevant procurement or development contract;

(b)submission of a request for type approval or type certification to the appropriate regulatory authority. For aircraft, submission of a request for type certification refers to a submission of a request for a new aircraft type certification;

3. ‘new facilities’ means facilities for which, by the cut-off date, neither of the following events has occurred:

(a)signature of the relevant development contract;

(b)submission of a request for planning consent to the appropriate regulatory authority;

4. ‘end date’ means the date after which halons shall not be used for the application concerned and by which date the fire extinguishers or fire protection systems containing halons shall be decommissioned;

5. ‘inerting’ means preventing the initiation of combustion of a flammable or explosive atmosphere by means of the addition of an inhibiting or diluting agent;

6. ‘normally occupied space’ means a protected space in which it is necessary for persons to be present most or all of the time in order for the equipment or facility to function effectively. For military applications, the occupancy status of the protected space would be that applicable during a combat situation;

7. ‘normally unoccupied space’ means a protected space that is occupied for limited periods only, in particular for undertaking maintenance, and where the continual presence of persons is not necessary for the effective functioning of the equipment or facility.
