Reaction to fire tests - Furnishing and construction products

Fire resistance tests in the building sector include all French regulatory evaluations (M classification, AM18), as well as the European regulatory ranking (Euroclasses, ignitability, Higher Calorific Value, non-combustibility). LNE offers manufacturers a comprehensive range of tests to enable them to meet regulatory requirements and market their products in Europe.

Placing construction products on the market

In order to be placed on the market, construction or furnishing products must meet performance requirements in terms of reaction to fire. Reaction to fire is defined as the ability of a product or material to sustain an external fire by its own combustion. The risk of spreading an existing fire to other parts of the building is assessed by testing the product under thermal loads. This is called fire rating. The purpose of these assessments is to prevent the rapid development of a fire and to enable people to be evacuated. To date, different types of classification coexist in France: the French M classification and loss of mass, and the European Euroclass classification. LNE carries out a wide range of tests to obtain these classifications.

Proposed reaction to fire tests 

  • M classification of rigid materials, (NF P 92-501, 504, 505 and 507)
  • M  classification for flexible materials, (NF P 92-503, 504, 505 and 507

The M classification allows the reaction to fire of the product to be assessed by quantifying its capacity to sustain a fire. This classification is established following a standardised test during which the product is exposed to a source of heat, using a device called an epiradiator. The test measures flammability, flame height and ignition time.

Euroclass classification tests

  • Euroclass classification at SBI, (EN 13823)
  • Euroclass classification of floor coverings, (EN 9239-1)

The " Euroclass " classification is a reaction classification system common to all countries of the European Union. It distinguishes between seven classes, separating floor coverings (which are considered different) and other materials. The Euroclasses tests are more comprehensive than the M classification because they take into account the smoke generated as well as any sprayed droplets. In order to obtain the CE marking to place their products on the European market, manufacturers must therefore have their performance evaluated according to this Euroclass system.

AM 18 tests

  • Loss of mass on upholstered seats (NF D 60-013) 

The loss of mass test is used to evaluate the reaction to fire of upholstered seats installed in rows and/or fixed to the floor. This test makes it possible to determine the non propagation of a fire between the seats but also to define a quantity of mass not to be exceeded for an upholstered seat.

Other reaction to fire tests

  • Non-combustibility performance (EN 1182)
  • Ignitability (EN 11925)
  • Determination of Higher Calorific Value (ISO 1716)
