The basic term that comes around when we discuss the subject of fire protection is fire resistance. Fire resistance is a capability of building components to meet fire requirements in fire exposure conditions/ when exposed to fire.  Fire resistance can be quantified as a measure of time, a time stamp during which the elements of building construction are able to fulfill  the performance criteria.
The fire resistance class is specified  through mix of letters and numbers. The letters indicate different performance criteria. 
Requirements for fire resistance classes:

  • Load bearing capacity (R)
  • Integrity (E)
  • Insulation (I)

The numbers, however, indicate the time the building element can  fulfill performance criteria while exposed to fire.  On the basis of fire test, the building element is assigned to one of the fire resistance classes: resistance to fire during 15, 20, 30, 45, 60, 90, 120, 180, 240 or 360 minutes
One of the additional criteria that apply to ,among others, fire dampers is smoke leakage (S)

 Fire dampers with EN 15650, EN 1366-2, EN 13501-3 + A1.

Fire resistance EIS 120, 90 and 60 - depending on the needs of the customer can choose the damper meets the specified criteria.

Fire dampers are available in two versions:  circular - from 100 to 630 mm diameter, and rectangular - sizes from 160x160 to
1000x500 mm,

Valves meet the criteria for tightness class "C". They are available with manual or severmotor Belimo.
