scope:
Specifies a method for determining the fire resistance of vertical and horizontal ventilation ducts under standardized fire conditions. The test examines the behaviour of ducts exposed to fire from the outside (duct A) and fire inside the duct (duct B). This standard is used in conjunction with prEN 1363-1. For evaluation of fire dampers see prEN 1366-2. For evaluation of smoke extraction ducts see prEN 1366-8.
