1. Values are based on 7'-0" to 7'-6" high doors. Adjust values for 7'-6" to 8'-6" high doors, by
adding the following factor:
1/2 second for widths up to 42"
1 second for widths over 42"
2. Values are based on 12'-0" floor-to-floor height. Adjust using factors noted for variation
from this standard.
Find rated speed in the 1st column. Select standard floor-to-floor performance time from box
under correct door type (side opening or center opening) and clear door opening width. Adjust
this time by adding factor if doors are over 7'-6" high, and adding or subtracting appropriate
amount per foot of travel over or under standard floor height of 12"-0".
