The Importance of EN 1365-1:2012 for Load-bearing Wall Fire Resistance Testing


Introduction to BS EN 1365-1:2012


BS EN 1365-1:2012 is a crucial European standard that specifies the method of testing the fire resistance of load-bearing walls, both internal and external. The test measures a wall's ability to resist the spread of fire from one side to another while maintaining its load-bearing capacity.

Understanding BS EN 1365-1 Fire Resistance Tests


The fire resistance test outlined in EN 1365-1 focuses on several key areas:


  1. Loadbearing Capacity(R): The walls ability to maintain a load. This is determined by measuring the vertical deflection of the wall.

  2. Insulation: The test evaluates how well the wall insulates and prevents the transmission of heat to the unexposed face. This is determined by measuring the temperature rise of the unexposed face of the wall with thermocouples.

  3. Integrity refers to the wall's ability to continue functioning without developing cracks or openings through which flames or hot gases can pass.


Application and Scope of BS EN 1365-1 Standard


This European standard applies to internal and external load-bearing walls and evaluates fire resistance without perforations such as doors, glazing, or fire-resistant ducts. The effects of these elements need to be separately established if included. The standard is not applicable to non-separating load-bearing walls, which can be tested as columns under EN 1365-4.


The fire resistance performance of external walls can be determined under internal or external exposure conditions. These standards are used in conjunction with EN 1363-1:1999.
