TS EN 13501-1 Fire Resistance Flammability Tests

TS EN 13501-1 Fire Resistance Tests

European Standard EN 13501-1 reacts to the fire classification procedure for all products and components. According to this standard, a reaction to a fire is that a product contributes to its decomposition under a certain fire (not to be confused with fire resistance).

The products are considered in relation to end-use applications, divided into three main categories:

  • Construction products;
  • Floor;
  • Linear pipe thermal insulation products;

Construction products are classified according to harmonized test methods on A1, A2, B, C, D, E and F Euroclasses. Products classified in a particular class are considered to meet all requirements of any subclass.

Products classified in the A1 and A2 grades are non-flammable (cement, concrete, minerals, glass, fiberglass, rock wool, ceramics, etc.), certified materials from B to F may burn in ascending order.

Flooring materials are classified according to A1, A2, B, C, D, E and F classes, followed by the abbreviation of “fl”.

Construction products and structural elements, fire classification section 1: Classification using the data obtained from behavior tests against fire.

In our country, increasing population, unplanned construction, construction of high and multifunctional buildings, fires and loss of lives and property in fire have increased. This is largely related to the materials selected during the design and construction of the building. According to the için REGULATION ON FIRE PROTECTION OF BUILDINGS gelen which became obligatory in 2007 year, TS EN 13501-1 standard and the European norms it covers are the classification of fire reaction adopted for construction materials in our country.

 Additional classifications

All materials are classified for A2 B, CD to obtain an additional classification regarding emission between smoke and production between flaming droplets and / or particles.

- “S” Smoke emission level:
values ​​range from 1 (missing / weak) to 3 (high)

- “D” flaming Production of droplets and / or particles: values ​​range from 0 (none) to 2 (high)

For class E, a single subclass d2 is provided.
For flooring products, additional classification duman s yalnızca is provided for smoke emission only.

According to TS EN 13501-1, you can get fire and fire reaction classification tests from our laboratory EUROLAB.
