Is ayble B1 certified? Fire Safety at Exhibition Stands

As of: May 2026

Fire safety at trade fairs is not a detail, but a requirement: Almost all organizers require that stand construction materials are at least flame retardant. This guide explains what fire safety class B1 means, why it is important, and the status of certification for ayble’s modular exhibition stand.

What does B1 according to DIN 4102-1 mean?

The standard DIN 4102-1 classifies building materials according to their fire behavior. Simplified:

Class	Meaning
A1 / A2	non-combustible
B1	flame retardant
B2	normally flammable
B3	highly flammable (not permitted in exhibition construction)

For exhibition stands, organizers typically require at least B1 (flame retardant) in their Technical Guidelines. Class B3 materials are not permitted.

Why is fire safety so important at trade fairs?

In large halls with many people and stands in close proximity, fire can spread quickly. Flame retardant materials delay fire spread and provide valuable time in an emergency. Therefore, the organizer may require proof of fire safety class for installed materials – if this is missing, closure of the stand may be threatened in the worst case. The guide How high are you allowed to build at a trade fair? → covers other construction requirements set by the organizer, such as the maximum build height.

How the ayble exhibition stand is certified

The ayble stand meets standard fire safety requirements on two levels:

• Frame system made of aluminum: The supporting system consists of aluminum and is therefore non-combustible.
• Graphic panels with B1: The graphic panels used are all fire safety certified with B1 according to DIN 4102-1 – i.e., flame retardant.

The stand therefore meets the typical requirements of organizers. You can use the corresponding certificate for registration at the trade fair if required. The guide Types of exhibition stands → summarizes which stand types benefit from this.

Plan fire safety from the start

Fire safety isn’t something to leave until the last minute. If you plan your presence in a structured way from the outset, you’ll automatically think about materials, rear wall cladding, and the organizer’s requirements. You’ll find a checklist in the guide Planning an exhibition stand →.

Frequently Asked Questions (FAQ)

Is the ayble exhibition stand B1 certified?

Yes. The aluminum frame system is non-combustible, and the graphic panels are all fire safety certified with B1 according to DIN 4102-1.

What does flame retardant (B1) mean?

B1 is a fire safety class according to DIN 4102-1 and stands for “flame retardant”. The material does not ignite easily and delays fire spread – the minimum class typically required in exhibition construction.

Do I need fire safety certification for the trade fair?

Frequently yes. Many organizers may require proof of fire safety class for the installed materials. Check the Technical Guidelines of the respective trade fair.

Is aluminum combustible?

No. Aluminum is non-combustible – therefore an aluminum frame system is particularly safe from a fire safety perspective.

Conclusion

B1 according to DIN 4102-1 means “flame retardant” and is the fire safety class typically required in exhibition construction. The ayble stand meets this requirement: The frame system made of aluminum is non-combustible, the graphic panels are all B1 certified. This ensures you are on the safe side with the fire safety requirements of most trade fairs.
