EN 13501-1 : 2018 Fire classification of construction products and building elements - Part 1: Classification using test data from reaction to fire tests - This European Standard provides the reaction to fire classification procedure for all construction products, including products incorporated within building elements. Products are considered in relation to their end use application. This document applies to three categories, which are treated separately in this European Standard: - construction products, excluding floorings and linear pipe thermal insulation products; - floorings; - linear pipe thermal insulation products. NOTE The treatment of some families of products is still under review and can necessitate amendments to this European Standard (see European Commission Decision 2000/147/EC).
The price of the Standard included all amendments and correcturs.

The British Standards Institution (BSI) is the UK National Standards Body (NSB). It publishes standards and provides a range of books, self-assessment tools, conferences and training services. It also represents UK economic and social interests in European and international standards organisations.
Fire reaction achieved by elements of structure, doors and other forms of construction is classified in accordance with BS EN 13501-1, excluding power, control and communications (which are covered by BS EN 13501-6).
It was once the case that to sell floor coverings throughout the individual European countries that now make up the European Economic Area (EEA) required assessment of products against more than 20 different national test standards relating to fire resistance. As this was not practical for most manufacturers and could lead to considerable confusion, the reaction to fire test methods have been harmonised.
EN 13501-1 consists of four European 'reaction to fire' test methods that can be applied to floor coverings. One or more of the tests are used to obtain a classification from A1fl (no contribution to fire) down to Ffl (no performance determined). Table 1 shows the required tests in combination.
For manufacturers of textile, resilient, laminate and hardwood flooring products, EN ISO 11925-2 and EN ISO 9239-1 are the most important test methods called up for classification. Commercial and contract application floor covering products will most probably be tested against the requirements which need to be met to obtain a class Bfl, Cfl or Dfl classification. For domestic products Class Efl is likely to be sufficient.
EN ISO 9239-1 describes a test procedure for assessing the burning behaviour (spread of flame and smoke development) of horizontally mounted floor coverings firstly exposed to a radiant heat source and then ignited with a pilot flame. The applied radiant heat flux (kW/m2) simulates the thermal radiation levels likely to impinge on a floor whose upper surface is heated by flames or hot gases or both, from a fire in an adjacent room or compartment.
The test is applicable to all types of floor covering including textile carpet, cork, wood, rubber, resilient, laminates and resins. It is used for classification against EN 13501-1 Classes A2fl, Bfl, Cfl or Dfl.
BS EN 13501-1 provides the reaction to fire classification procedure for all construction products, including products incorporated within building elements. Products are considered in relation to their end use application. BS EN 13501-1 separates these types of products into three categories, which are:-
The aim of this European Standard is to define a harmonized procedure for the classification of reaction to fire of construction products. This classification is based on the test procedures listed in this manual. Fire reaction achieved by elements of structure and other forms of construction is classified in accordance with BS EN 13501-1, excluding power, control and communications (which are covered by BS EN 13501-6).Specifically, the following products are covered under BS EN 13501-1 (within their end use):
The test specimen shall be taken from a sample which is sufficiently large to be representative of the product and shall be cylindrical with a volume of 76 8 cm3and diameter of 45mm and a height of 50 3mm.
After conditioning a 0.5g sample is selected and placed in a crucible inside the pressurised vessel (bomb), together with combustion aids if necessary (benzoic acid or paraffin oil). The bomb is then filled with 99.5% pure oxygen to a pressure of 30MPa. The bomb is inserted into the testing apparatus which fills with water and the sample is ignited. The test apparatus measures the rise in temperature of the water and calculates the calorific value of the sample, taking into account any combustion aids.
Each test specimen is then fixed in the trolley and is exposed to a flame from a burner placed at the bottom of the corner. The flame is obtained by combustion of propane gas and gives a heat output of 30.72kW.
These quantities are recorded automatically and are used to calculate the Heat Release Rate (HRR) and Smoke Production Rate (SPR). A visual observation is also measured for flaming droplets and horizontal spread of flame.
Fire classification of construction products excluding roof coverings is made according to classification standard EN 13501-1. The test methods and classification criteria for fire classes are presented in classification standard EN 13501-1. Classification of roof coverings is made according to classification standard EN 13501-5.
Construction products have five European reaction to fire test methods. Based on the test results the products are divided into seven main classes: A1, A2, B, C, D, E and F for construction products excluding floorings and linear pipe thermal insulation products. Classes for floorings are A1fl, A2fl, Bfl, Cfl, Dfl, Efl and Ffl and for linear pipe insulations A1L, A2L, BL, CL, DL, EL and FL.
Regulations and guidelines concerning fire safety of buildings are shown in degree of the Ministry of the Environment on fire safety of buildings.

European Standard EN 13501-1 reacts to the fire classification procedure for all products and components. According to this standard, a reaction to a fire is that a product contributes to its decomposition under a certain fire (not to be confused with fire resistance).
Construction products are classified according to harmonized test methods on A1, A2, B, C, D, E and F Euroclasses. Products classified in a particular class are considered to meet all requirements of any subclass.
In our country, increasing population, unplanned construction, construction of high and multifunctional buildings, fires and loss of lives and property in fire have increased. This is largely related to the materials selected during the design and construction of the building. According to the iin REGULATION ON FIRE PROTECTION OF BUILDINGS gelen which became obligatory in 2007 year, TS EN 13501-1 standard and the European norms it covers are the classification of fire reaction adopted for construction materials in our country.
In order to be used in a building, insulation products need to pass British Standard tests regarding fire protection. The two main standards under which such products will be assessed are BS 476-1: Fire tests on building materials and structures and BS EN 13501-1: Fire classification of construction products and building elements. The results of these tests are used by specifiers and contractors to determine the best fire rated insulation available for their needs.
The classification system defined in BS EN 13501-1 is typically the primary recognised standard in the construction industry. The process for classification under this standard involves a combination of up to five rigorous tests designed to assess the product on a range of characteristics, including combustibility, heat levels, flame spread and smoke release. Once tested, the product receives an official classification of its fire rating, known as a Euroclass rating.
