Doorset
The complete fire door assembly as it was tested: door leaf, frame, seals, hinges, closer and other hardware. A fire rating belongs to the doorset, not the leaf alone.
FD30
A fire door rating meaning the doorset held back fire for 30 minutes in testing.
FD30S
An FD30 fire door that also restricts the passage of cold smoke, usually by fitting smoke seals. The S stands for smoke control.
FD60
A fire door rating meaning the doorset held back fire for 60 minutes in testing.
Intumescent seal
A strip fitted around a fire door or frame that expands when heated, closing the gap around the door to block fire and hot gases. Paint over it and it may not expand.

Responsible Person
The person legally accountable for fire safety in a non-domestic building under the Regulatory Reform (Fire Safety) Order 2005. Usually the employer, owner or managing agent.
