Reaction to fire testing

Evaluate a material's behavior when on fire

Knowing a material's reaction to fire allows us to foresee its behavior in a fire: how it will start, evolve and spread the combustion. To evaluate materials' reaction to fire and classify them according to their performance you need to determine their levels of flammability, combustibility, smoke toxicity and combustion heat, among others.

Manufacturers of products which may be exposed to a possible fire should develop materials that are less vulnerable to fire to ensure the safety of their applications in means of transportation, buildings or any other environment where there is a risk of fire. The applicable legislation varies according to the sector and the product's use.

Accredited Laboratories for reaction to fire tests

Applus+ offers a reaction-to-fire testing service, with accredited and recognized laboratories (IMO VKF-IAEA, ELOT, among others). We are Europe's leaders in equipment and annual tests by volumen. Applus+ is Notified Body No. 370 for the Construction Products Regulation and for all products that have requirements for fire resistance and reaction.

Our service includes:

  • Comprehensive management and execution of the testing plan
  • Test tooling design and manufacturing
  • On-line test visualization
  • Data post-processing and test report issuing
  • Consulting for product improvement
  • Training for technicians

We perform tests under the international standards applicable to various sectors:

  • Construction (EN 13501-1, UNE 23727, EN 13773, EN 1021-1/-2, etc.)
  • Railways (prEN 45545-2, NF F 16101, etc.)
  • Naval (Tests according to Res. MSC.307[88], etc.)
  • Aeronautics (AITM, FAR/CS 25 Ap. F, etc. )
  • Automotive (ISO 3795, FMVSS 302, DIN 75200, UNE 26234, and various technical specifications)
  • Electrical (IEC's, UL 94, EN's, etc.)
  • Thermal tests (EN 12664, EN 12667, U calculation [thermal transmittance], etc.)

We perform the following range of tests:

  • Classification of Euroclasses (A1, A2, B, C, D, E and F with the "s" subscripts for smoke, "d" for drip, and "fl" for flooring materials)
  • Classification of material M0 to M4
  • Flammability and oxygen index
  • Accelerated aging and flammability of textile materials
  • Fire behavior of cables and electrical components
  • Opacity of smoke emitted by burning materials

To do so, we have fire reaction and resistance laboratories and our own highly specialized equipment:

  • SBI (single burning item)
  • Radiant panel
  • Calorimeter bomb
  • Non-combustibility equipment
  • Small burner

We test products from various industries:

  • Textiles
  • Thermal insulation materials
  • Wood or plastic coatings or floorings
  • Protection of structures and paints
  • Mattresses
  • Toys
  • Aerosols
  • Electrical cables, pipes and gutters
