Smoke seal requirements may be different.  You do need to check w/ local code.

This may seem like a silly question but:

I need to install a new door for a condo  (Arlington County, Virginia which 
uses Boca 96).  It is the entrance door from the condo to the (interior) 
corridor.  Per Boca,  Table 1011.4, Use Group R,  the Corridor Fire 
Resistance Rating (with sprinker system) is 1/2 hour so per table 717.1,  the 
door only needs to be rated for 20 minutes.

The steel doors at Home Depot indicate that they are rated for 1-1/2 hours 
but apparently the Home Depot staff says that the doors do not necessarily 
comply with county requirements for fire rating.  What other county fire 
requirements are there likely to be?  If a door is rated for 1-1/2 hours 
wouldn't it also qualify for a 20 minute requirement?

Going to the county building department and actually asking somebody is 
always a last resort ...
