There are two standrds relating to fire exit doors BS EN 179 relates to exit doors where the occupants are familiar with the premises and accepts handles,
Where persons are unfamiliar or panic situations could arise then the standard is BS EN 1125 which relates to panic fastenings.
If you do not have access to the standards have a look at the Door & Hardware Federation site at http://www.dhfonline.org.uk/downloads/pub100.pdf they have some best practice guides which can be downloaded plus other guides on door hardware.
