BS 1245:2012

This British Standard specifies requirements for the design, fabrication and performance of pedestrian doorsets with leaves manufactured from steel skins with a minimum thickness of 1.0 mm, where all surfaces are steel and the edges are steel and mechanically fixed. It applies to doors whose leaves are infilled with materials of either recycled cardboard honeycomb or mineral wool.

It covers both complete doorsets, and door frames that could be used for doorsets with non-metallic leaves.

It applies to doors fitted into frames in a factory, to be installed vertically (within 15°) into buildings, as single or double units, in coupled assemblies when appropriate, of the following types:

1. single leaf single-swing doors with or without side and over panels;

2. double leaf single-swing doors with or without side and over panels;

3. single leaf double-swing doors with or without side and over panels;

4. double leaf double-swing doors with or without side and over panels.

It is applicable to assemblies up to the point of installation.

This British Standard does not specify requirements for fire resistance or smoke control characteristics.
