DIN EN 13501-1:2019-05

Classifying the reaction to fire of construction products consistently across Europe

The DIN EN 13501-1 specifies the procedure for the classification of the reaction to fire of construction products and building elements. It provides the basis for the consistent classification of construction materials throughout Europe according to their contribution to fire initiation and development. The standard helps manufacturers, planners, and testing bodies assess and document fire safety requirements for construction products in a transparent manner.

What does DIN EN 13501-1 cover?

The standard defines the Euroclasses for reaction to fire of construction products and describes the associated testing and classification procedures. It covers the classification of construction products, floor coverings, and linear pipe thermal insulation products based on standardized fire tests and assigns them to classes A1 to F, A1fl to Ffl, or A1L to FL.

The assessments focus on ignitability, heat release, flame spread, smoke production, and flaming droplets or particles. The standard also sets out rules for the direct and extended fields of application and for preparing classification reports.

Topics covered

• Classification of the reaction to fire of construction products
• Euroclasses A1 to F for construction products
• Euroclasses for floor coverings and linear pipe thermal insulation products
• Smoke production classes s1, s2, and s3
• Classification of flaming droplets and particles: d0, d1, and d2
• Test methods in accordance with EN ISO 1182, EN ISO 1716, EN 13823, and EN ISO 11925-2
• Direct and extended fields of application of test results
• Requirements for classification reports
• Application under the European Construction Products Regulation

Practical relevance

The fire classification of construction products is a key component of structural fire protection. DIN EN 13501-1 provides a consistent basis for this and enables the comparable assessment of construction materials and products throughout Europe. It supports the selection of suitable products for buildings with different uses and provides an important basis for demonstrating compliance with building regulations.

The classifications for reaction to fire, smoke production, and flaming droplets or particles are particularly relevant because they form the basis for product selection, tender specifications, CE marking, and evidence required by building authorities.

Changes compared with DIN EN 13501-1:2010-01

The following changes have been made compared with the previous edition:

• Updated reference to Construction Products Regulation (EU) No 305/2011
• Updated normative references
• Revised provisions for class F
• Inclusion of linear pipe thermal insulation products in the classification system
• Editorial revision of the standard

Target audience

• Fire safety planners
• Architects
• Civil engineers
• Manufacturers of construction products
• Testing and certification bodies
• Experts in structural fire protection and building authorities
• Professionals in construction product safety and CE marking

Conclusion

DIN EN 13501-1 provides the basis for the consistent assessment of the reaction to fire of construction products throughout Europe. It supports manufacturers, planners, and testing bodies in the standards-compliant classification and use of construction products in preventive fire protection.
