Technical Information Fire
Technical Information Fire
Sustainability refers to the practice of meeting present needs without compromising the ability of future generations to meet their own. It involves a balanced approach to economic growth, environmental protection, and social well-being.
Resistance To Fire
Resistance to Fire refers to the ability of a material or building element (such as walls, roofs, floors, or doors) to withstand fire and retain its structural integrity, insulation, and stability for a specified period of time during a fire event.
The following aspects are controlled:
- Resistance to flames, fumes and exhausts
- Mechanical stability
- Thermal insulation (symbol : R)(Symbol : E) (symbol : l)
Class 0
The non-combustibility test to assign Class 0 is carried out to the ISO-DIS 1182.2 standard, which envisages to a very small sample material to 750 C and checking the following parameters:
- Formation of flames
- Increase in temperature
- Loss of weight
Class 1-5
No organic substances achieve Class 0, so they must be classified with other methods. For the Italian laws, they are:
- CSE RF 1/75/A – Suspended materials attacked by flames on both sides
- CSE RF 2/75A – Materials attacked by flames on one side
- CSE RF 3/75A – Materials subject to one flame and radiant heating
- Methods CSE RF 1/75A or CSE RF 2/75A are used according to the type of material.
- The Fire Reaction Class of the product is established by combining these categories.
