What is DIN 4102?

DIN 4102-1 Fire behaviour of building materials and elements Part 1: Classification of building materials Requirements and testing. 2. DIN 4102-1 fire test to building material – Standard Brief： This standard defines fire behaviour classes for building materials and specifies requirements and test methods for each …

What is fire class B3?

The flammability class B1/B2/B3 according to DIN 4102 indicates the way that a foam reacts to flames. We have a range of foams with reduced flammability (category B1/B2/B3 foams) that are ideal to use in standard filling and insulating applications.

What is B1 material?

European Flame Retardant Standards M1 B1 is the European flame retardant standard for contract drapery. It is used across Europe so companies are aware that a fabric and in turn the curtain made from that fabric is flame retardant and can be used safely in a commercial environment.

What is B1 foam?

B1 FOAM meets the fire resistance class B1, which is the best fire resistance classification that can be obtained for a PU-foam. B1 FOAM has a high insulating value, thermic as well as acoustic, and meets all noise standards to 57 db. B1 FOAM has an excellent adhesive power to most materials.

What is a Class A fire rating?

Flame spread classifications are developed using the American Society for Testing and Materials (ASTM) “tunnel test.” Class A fire ratings indicate flame-spread of 0-25 and smoke developed between 0-450 and is the highest of the ratings. The Class A or Class I rating indicates superior fire protection.

What is B3 foam?

FM365 is a rapid curing, high yield, one component gun grade expanding polyurethane foam that is suitable for general gap filling, bonding and insulation applications.

What is B2 fire foam?

Firefoam B2 Gungrade is a quick setting fire rated, one-part polyurethane foam designed for application by any standard foam applicator gun. Read more… High degree of fire rating: slows down the passage of flames and smoke in comparison to standard B3 grades.

What is fire class B1?

The valid norm is differentiated into two fire protection classes. ‘A’ stands for non-flammable and ‘B’ for flammable materials. Class B is relevant for PU foam. This is then subdivided into the following levels: B1 = low flammability.

What is B2 rated foam?

B2 Fire Rated Expanding Foam works a treat for installing frames, filling cavities and for use in passive fire protection systems where DIN 4102 B2 fire class is required. This filler also delivers great thermal and acoustic insulation when used around doors and window frames.

What does fire rating B mean?

Class A fire retardants have a flame spread rating of between zero and 25. These materials are effective against severe fire exposure. Class B fire retardants have a flame spread rating of between 26 and 75. These materials are effective against moderate fire exposure.
