HTM 58: 2005 - INTERNAL DOORSETS is the latest NHS guidance on
doors and doorsets generally. It replaces a far more extensive
version and it is assumed that much of the previous guidance is
now incorporated in Building Regulations Approved Documents or
British Standards. For example, clear opening widths, vision
panel sizes and other details of accessible doorsets should be
derived from BS 8300 and Part M.
The Leaderflush Shapland guide document 'Designing with Doors
and Doorsets' provides detailed guidance on the Regulations and
Standards. HTM 58 recognises that - "The high performance
standards required of door leaves, frames and ironmongery in
health buildings can best be met when these components are
accurately fitted and matched in the factory and delivered to
site as a complete unit" - i.e. with a doorset as opposed to a
door assembly. Various doorset frames are illustrated in
relation to partition thickness and door leaf positioning. These
can all be accommodated with LS Group doorsets, as shown.
Thresholds are generally not needed but where incorporated
must sit flush with the floor.

Air transfer grilles should be avoided wherever possible,
although - there are situations where they are required - see
page 22. Ironmongery should be factory fitted as part of the
complete doorset although protruding items may be delivered
separately. HTM 59 covers ironmongery in detail (although the
vision panel positions shown in the Appendix do not comply with
BS 8300). When designing door positions, they should be located
away from room corners so that a nib of at least 50mm
(preferably 100mm) should be left for fixing, full architraves
and projecting ironmongery - although Part M requires a 300mm
nib where the door may be operated from a wheelchair.
Where access to patients may be required in an emergency -
such as bathrooms and toilets - emergency access facilities will
be needed.
An operation and maintenance manual should be passed to
maintenance staff: this is supplied by Leaderflush Shapland with
the doorsets. It is also essential to consult the manufacturer
before carrying out work to fire doorsets during maintenance.
