DIN EN 1366-2:2014-10

This Part of EN 1366 specifies a method for determining the fire resistance of fire dampers installed in fire separating elements designed to withstand heat and the passage of fire, smoke and gases at high temperature. The Standard is used in conjunction with EN 1363-1. This standard is not suitable for testing fire dampers in suspended ceilings. The purpose of the test is to evaluate the ability of a fire damper to prevent fire and smoke spreading from one fire compartment to another through the air ductwork system which may penetrate fire separating walls and floors. The fire damper is attached (directly or remotely via a section of ducting), to a fire separating element in a manner representative of practice. Tests are performed starting with the fire damper in the open position to expose the temperature sensing element of the fire damper to furnace conditions. This standard is not suitable for testing non-mechanical fire dampers (see prEN 1366-12).
