Full test report: FTC 20/199, available on request
Verified fire performance: Stability (R) 120 minutes, Integrity (E) 120 minutes and Insulation (I) 60 minutes. The tested assembly achieved E120, exceeding the minimum E60 integrity requirement for Class B doors under SANS 1253.
The tested assembly used a single-leaf door with a symmetric MgO composite core and Meranti hardwood edges, mounted in a 25 × 50mm steel frame with three hinges and a door closer. It was tested as an outward-opening fire-escape door with a certified 3-point panic push-bar and as an inward-opening exit door with a standard lockset. The Class B certification applies when installed in accordance with the relevant tested configuration.

Suitable where a 120-minute fire-rated door is required under South African building regulations, including:
- Stairwells and lift-lobby shafts
- Major fire-break walls in commercial, industrial or public buildings
- High-risk fire-compartment boundaries
- Main escape routes in multi-storey developments
- Areas requiring SANS 1253 Class B compliance
Installation note: The Class B rating is valid only when the door is installed as a complete assembly equivalent to the tested configuration, including the matching steel frame, three hinges, door closer and the appropriate certified panic push-bar or approved lockset.
Frequently asked questions
What is a Class B fire door?
A Class B fire door provides 120 minutes (2 hours) of fire resistance. In South Africa, Class B fire doors are classified to SANS 1253 and tested to SANS 10177-2. This assembly achieved R120/E120/I60: 120 minutes of structural stability and flame integrity, and 60 minutes of thermal insulation.
What does R120/E120/I60 mean?
Stability (R) means the door remains structurally intact for 120 minutes. Integrity (E) means flames or hot gases do not pass through for 120 minutes. Insulation (I) means the unexposed face remains within the required temperature limits for 60 minutes.
Where are Class B fire doors required?
Class B fire doors are typically used in stairwells, lift lobbies, corridors and fire compartments in commercial buildings, hotels, hospitals and multi-storey residential developments. Requirements depend on SANS 10400-T and the project fire strategy.
