Insulation values of spaces with special characteristics
of two or more groupings
Where a space has the special characteristics of two or
more space groupings, the structural fire protection time of the divisions
should be the highest for the space groupings concerned. For example,
the structural fire protection time of the divisions of emergency
generator rooms should be the highest value for the space when the
space is considered as being a control station (D) and a machinery
space (A).
