Twenty-minute doors tested without hose stream

Doors and frames may also be rated as 20 minutes without a hose stream. These doors have succesfully passed a 20-minute fire test, with the omission of the hose stream test, and bear a label that specially states "Twenty-Minute-Rating Tested Without Hose Stream." These doors may be provided with vision lights only limited in size by the door manufacturer's fire labeling procedure authority.
