We all know that the doors which prevent flames from spreading between rooms are called fire doors, fire resistant doors or flame proof doors. Technically they can have different name codes, even when they are referring to the same type of door. Thus, for example, what is the difference between FR 60 doors, RF 60 doors and EI1 60 – C5 doors?

In principle there is no difference beyond the name. FR 60 and RF 60 doors are the same. ‘FR’ stands for ‘Fire resistant’, and ‘RF’ stands for ‘Resistentes al Fuego’ which means the same thing in Spanish. There is even the less common term FP, which stands for ‘Flame Proof’. In all these cases the number refers to the minutes during which the door is guaranteed to withstand the propagation of flames between rooms.

In Spain, the most widespread term is set out by Royal Decree 314/2006, of 17 March 2006, which approves the Technical Building Code and which determines that FR 60 or RF 60 doors can be called, for example, EI1 60 – C5 doors.

In this case, the letter ‘E’ refers to the integrity of the door and its ability prevent the passage of flames or gases, the letter ‘I’ refers to the insulation of the door and its ability to prevent the transmission of fire due to heat transfer and the number 1 clarifies that during testing, measurements were made at a distance of 25 mm from the pane (or 100 mm when the number is 2). Finally, the number 60 refers to the number of minutes during which the door will hold, preventing the spread of fire and C5 clarifies that the door withstands a durability test of 200,000 cycles.
