Growing demand for fire doors

Growing demand for fire doors

There has been a growing demand for the supply of fire doors and FFETA feels that it is imperative to assist our members with important information on them. Below is a guideline on the different classes of fire doors and what to look out for.

Why a need for fire doors?
In general, a fire door is required where the spread of fire and/or smoke from a fire needs to be contained within a specific area.  Location, classification, and size of fire doors need to be determined in accordance with the applicable building and safety regulations, as well as the project application (commercial, industrial, residential, etc.).

The classification of fire doors in the SANS 1253, South African National Standard is based on the following parameters: 

  • Stability: The ability of a fire door to fulfil its design function of keeping an opening closed in the face of a fire so that no fissure or opening wider than 25 mm develops.
  • Integrity: Enables a door to resist fire without the development of perpendicular through openings wider than 6 mm and longer in total than the largest dimension of the door.
  • Insulation: The ability of the door to prevent the transmission of enough heat to raise the mean unexposed face temperature by more than 140O C above the initial temperature.
  • Impact Test: The door is to resist two successive impacts of a sandbag 250 mm in diameter and weighing 27 kg, without the formation of any opening wider than 25 mm. The test is carried out after the test door has been allowed to cool down once the period of required stability has been achieved. The test is only conducted in respect of Class D doors.
Below is a table on the different parameters and the class of the Fire doors.

Note: the rating of a fire door is based on its stability parameter, for example: Class A fire doors are considered a 1-hour fire rated door, Class B fire doors are 2-hour rated, etc.

Most importantly, members need to ensure that all doors and frames are labelled with the manufacturer’s name, unique identification number classification as per SANS 1253, and year of manufacture. (This information is generally contained on a small metal plate/tag fixed on the inside of the door frame and on the door leaf).
