M1 M2 M3 M4 Flammability Tests (NF P 92-5XX)

Flammability tests are a critical part of providing reliable consumer products. These tests include textile products, special clothing, aviation and transport, bedding and furniture materials, and many more.

All consumer products must meet safety requirements and regulations before they are placed on the market, including combustion, heat and smoke discharge criteria.

Fireproof tests measure how easily the materials can ignite, how quickly they burn, and how they react when they burn. Materials are subjected to vertical or horizontal flammability tests depending on their technical properties. During vertical flammability tests, it is observed how long the sample has burned and whether it has dripped burning particles during the time it has burned after the ignition flame has been removed. On the other hand, during the horizontal flammability tests, it is observed whether the material continues to burn after the flame is taken, after which the combustion rate of the sample is calculated.

Fireproof testing of beds and furniture is also an important part of ensuring fire safety for consumers. In these fireproof tests, measurements such as heat emission, smoke emission and opacity, combustible gas emission and total mass loss are made. These tests ignite beds and furniture with a burning cigarette or a larger flame to determine how a product will react in case of an accident or deliberate fires.

Fireproof testing methods are used in advanced laboratories to evaluate products and materials or to comply with industry standards and regulatory requirements. The main standards that are taken as basis are French standards.

  • NF P92-501 Safety against fire - Building materials - Reaction to fire tests - Hard materials or flexible materials thicker than 5 mm
  • NF P92-503 Safety against fire - Building materials - Reaction to fire tests - Electrical burner test for flexible materials
  • NF P92-504 Safety against fire - Building materials - Reaction to fire tests - Flame retention test and flame spread rate
  • NF P92-505 Safety against fire - Building materials - Reaction to fire tests - Drip test for thermal melting materials
  • NF P92-506 Fire safety - Building materials - Floor
  • NF P92-507 Fire safety - Building - Interior equipment - Classification according to fire response
  • NF P92-512 Safety against fire - Building - Reaction to fire tests - Determination of strength of fire reaction (classification and testing of materials)

French standards have also introduced a classification between M1 and M4. According to this,

  • M1 - Non-flammable
  • M2 - Low flammability
  • M3 - Moderately flammable
  • M4 - Flammable

Many countries have issued regulations and standards, particularly in order to achieve the lowest acceptable level of fire protection of building materials. Designers must comply with these guiding requirements. Such fire regulations are highly regarded by the European Union countries.

The regulations take into account the following basic requirements for fire safety:

  • Fire and flames and fumes must be limited
  • The load carrying capacity of the structure must be maintained for a certain period of time.
  • The spread of flames to other structures must be limited
  • People should be able to leave the building in case of fire or be easily rescued
  • Rescue teams must be secured
