When designing display media, whether for indoor or outdoor use, safety is of paramount importance.
Among the French standards governing the reaction to fire of materials, M1 certification occupies a central place.
But what does this certification really mean, and what other classifications should you consider for your billboards?
M1 certification and reaction to fire classifications
French standard NF P92-507 classifies materials according to their fire behavior.
Here are the main categories:
-
M0: Non-combustible and non-flammable materials, such as cement or brick.
-
M1: Combustible but non-flammable materials, i.e. they do not propagate flames or produce smoke in the event of fire.
-
M2: Low-flammability materials.
-
M3: Moderately flammable materials.
-
M4: Highly flammable materials.
M1 certification is therefore awarded to materials which, although combustible, do not ignite easily or contribute to the spread of fire.
This characteristic is particularly sought-after for materials used in public places, especially at indoor events. The importance of M1 certification for indoor billboards
In establishments open to the public (ERP), regulations require the use of materials that meet strict fire safety standards. Suspended display media, such as tarpaulins and banners, must comply with M1 standards to minimize risks in the event of fire.
Opting for M1-certified panels not only guarantees compliance with current regulations, but also provides enhanced protection for occupants and property.
What about panels for outdoor use?
For outdoor displays, fire regulations are generally less stringent.
However, it is essential to choose materials that are adapted to climatic and environmental conditions. For example, PVC tarpaulins are commonly used for short-term outdoor promotional communications.
Although M1 certification is not always required for outdoor substrates, it is advisable to assess the risks specific to each environment and opt for materials offering a good compromise between durability, print quality and safety.
Conclusion
Fire safety is a major consideration when choosing materials for your billboards. M1 certification ensures that your displays are flame-retardant, meeting ERP requirements and guaranteeing better protection in the event of fire.
For outdoor displays, although M1 certification is not systematically required, it is crucial to select materials suited to the conditions of use.
