The minimum fire resistance required for guest room doors and door frames
Guest room doors and door frames require 20 minutes of fire resistance. By querying the "National Standards of the People's Republic of China - World Trade Organization", we learned that all guest room doors and door frames must have at least 20 minutes of fire resistance. The fire resistance performance of fire doors is divided into Class A, Class B, Class C and Class D, which correspond to fire resistance integrity ≥90min, 60min, 30min and 15min respectively. Among them, the fire resistance performance requirements of residential entrance fire doors are Class A or Class B, and the fire resistance performance requirements of evacuation passage fire doors are Class A or Class D.
