EN 13501-1 Fire Classification of Building Materials and Structural Elements - Part 1: Classification Using Data from Reaction to Fire Tests

In the EN 13501-1 standard, which is a European standard, classification criteria are explained using the data obtained from the reaction to fire tests of building materials and building elements.

Specifically, the following products are covered by the EN 13501-1 standard:

• Construction products
• Slabs
• Linear pipe thermal insulation products

Within the scope of the standard, fire resistance is a measure of one or more of the following:

• Slump resistance (load carrying capacity), which is valid only for load-bearing elements and indicated by an “R” in the European classification for fire resistance performance.
• Fire resistance performance Resistance to fire penetration (integrity), denoted by an “E” in the European classification.
• Fire resistance performance Resistance to excessive heat transfer (insulation), denoted by an “I” in the European classification.

Fire resistance is determined in minutes. This is about time in a standard test, not real time.

The fire resistance tests (alone or in combination, depending on the product) for compliance with the EN 13501-1 standard are:

• EN ISO 1182 Flammability test
• EN ISO 1716 Heat of combustion test
• EN 13823 Single burning substance test
• EN ISO 9239-1 Radiant panel test (floors only)
• EN ISO 11925-2 Single flame source test

After the tests carried out, the materials are classified in three ways:

• The main classification is shown from A to F (A is the highest classification and F is the lowest classification).
• The smoke classification is indicated by the alphanumeric combination between S1 and S3 (S1 being the highest and s3 the lowest).
• The flaming droplet classification is indicated by the alphanumeric combination of D0 to D2 (D0 is the highest classification and d2 is the lowest classification).

In short, the EN 13501-1 standard provides a fire reaction classification method for all building products, including those falling under the building elements group except for power, control, and communication cables covered by the EN 13501-6 standard.

Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization provides classification services by using the data obtained from reaction to fire tests of building materials and construction elements within the scope of EN 13501-1 standard, with its trained and expert staff and advanced technological equipment. also gives.
