Anyone know what the max force required to open a sliding door is or where can I find it. BS7036 does not provide for sliding doors, unless I have overlooked it.

are we talking fire door, final exit...?
The only thing I know of is the H &S requirement for it to be operable without risk of injury

This is a sliding door across a final exit.

Would this be it?
10 Break-out
10.1 It is essential that powered operation ceases
immediately upon break-out occurring where the
door or screen is fitted with such a facility
(see Figure 7).
10.2 The resistance to break-out should be not
greater than 220 N at the leading or meeting stile.
10.3 Where a break-out facility is fitted to a glazed
door it is essential that the glazing meets the
break-out resistance without shattering
(see 6.1 of Part 1).

How many persons are likely to pass through to a place of safety?
Would rather it open outwards though the guidance has been watered down on this.

ps 220 N is a lot of N!

Not really Dominic. This is for a door which would break out. Different dymanics needed for a door which must be drawn sideways.

Up to 35 persons. Rather it opened out too but it doesn't in this case and that's why I am trying to build a case for it to be changed.

Its just that in some health establishments here where sliding doors are used they are designed to pivot outwards in the direction of travel under certain pressure.

Factors against?
Non-protected route?
Usage of premises?
Mobility of occupants?
High risks?
etc
Is this used on a regular basis or just as MoE?
Could you bring security into it and sell it that way, ie Crash bar?

This is a normal in out/door to a small sandwich bar 10M x 10M. The occupier does not want the auto sliding doors because of the annual maintence and service costs, because the premises are so small it opens when anyone picks even their nose and it keeps the place like a freezer in winter.
The landlord will not allow the doors to be changed to a simple swing type and I am looking for any angle. They are linked to the fire warning system and failsafe to open on operation of system and in the event of a loss of mains power.

Why not ask the Guild of Architectural Ironmongers what their recommendation is? They've got good technical advice.
