Ecodek are now the ONLY UK manufacturer of Wood Polymer Composite Decking to have products tested to these BS EN ISO 9239-1 and 11925-2 standards; and as such we feel that our product performance sets us aside as the UK leading manufacturer and supplier of Wood Composite Decking products.
Ecodek AT 21mm Decking Boards have been tested to the following fire test standards :
BS EN ISO 11925-2 : 2010 – Ignitability of Building Products subject to direct impingement of flame
BS EN ISO 9239-1 : 2010 – Fire Tests for Determination of Burning Behaviour of Floor Coverings
Fire Safety Classification
The way in which material and construction products react to fire is key to ensuring people’s safety in case of fire at a construction site or in a completed building. Fire safety in buildings is one of the basic requirements for construction products in the EU Construction Products Regulation (CPR).
“Fire reaction” indicates the way the material behaves as a combustible.
Construction products’ reaction to fire is determined through Euroclasses. The Euroclasses were introduced following a resolution by the Commission (2000/147/EEC), from February 8, 2000, to create a common platform for the comparison of the fire properties of construction materials.
Fire testing of the products is conducted in accordance with harmonised testing methods. As defined by a series of European standards, it includes several tests and related performances:
- Classification for combustibility. Class A1 is non-combustible and the requirement level cannot be combined with any additional class mentioned below.
- Additional classification for smoke development, identified by symbol s.
- Additional classification for burning droplets, identified by symbol d.
Fire safety in buildings primarily concerns personal safety, but also includes the protection of material values. Data from fire accidents indicates that smoke and toxic gases cause the majority of deaths. Smoke and toxic gases kill long before the temperature has risen or flames have developed. Consequently, the main design requirement from a personal safety perspective is that buildings are constructed and configured to ensure that people can get to safety and the emergency services have the capacity to respond in the event of a fire.
The requirements for the materials used and the structures are determined by the building use, size, fire load and operation. Fire safety requirements in the national building regulations are often based on fire development (standard fire curve).

Fire Classification of materials: Reaction to fire (fire growth)
If a fire should occur, it is important that the building can be evacuated as quickly as possible in order to save lives. The time available for evacuation depends on the building materials and their fire properties.
The fire safety in construction products is determined through Euroclasses. The Euroclasses were introduced following a resolution by the Commission (2000/147/EEC) from February 8, 2000 to create a common platform for the comparison of the fire properties of construction materials.

Fire resistance tests for Euroclasses:
Fire resistance tests for building products – Non-combustibility, EN ISO 1182.
Fire resistance tests for building products – Determination of calorific potential, EN ISO 1716.
Fire resistance tests for building products – Building products, except for flooring materials exposed to thermal heat from a gas burner (SBI), SS-EN 13823.
Fire resistance tests for building products – Ignitability of products subjected to direct impingement of flame – Part 2: Single-flame source test, EN ISO 11925-2.
Fire resistance tests of floorings – Part 1: Determination of the burning behaviour using a radiant heat source, EN ISO 9239-1
Note: The purpose of the SBI test method (Single Burning Item test) is to use a larger sample model compared to the standard test methods in order for the test results to better correspond to a full-scale reference fire development phase. Experience shows that the SBI method works less well for products that consist of multiple layers, such as lightweight sandwich panels of polystyrene with a surface layer of metal. The results from the SBI method tend to depend on the location of the test object, and a standard with detailed instructions for mounting and fixing for reaction to fire testing of the test object (EN 15715) has therefore been developed.
The main properties to determine the Euroclass for a specific product is its non-combustibility, ignitability, flame spread, calorific value as well as the development of smoke and burning droplets. Depending on the outcome of the various properties, the product is assigned a fire classification as shown below.
Euro class Example
A1, A2 Stone wool, gypsum board
B Painted gypsum board
C Gypsum board with paper-based wallpaper
E Fire-retardant EPS
F Non-tested materials, EPS
Additional classes for smoke development
s1 the structural element may emit a very limited amount of combustion gases
s2 the structural element may emit a limited amount of combustion gases
s3 no requirement for restricted production of of combustion gases
Additional classes for burning droplets
d0 burning droplets or particles must not be emitted from the structural element
d1 burning droplets or particles may be released in limited quantities
d2 no requirement for restriction of burning droplets and particles
Class A1 is non-combustible and the requirement level and cannot be combined with any additional class.
Class A2 is also classified as non-combustible as no flashover occurs for the application of the products in these classes.
For classes A2 to D there are additional classes for smoke development s1, s2 or s3, and the amount of burning droplets emitted d0, d1 or d3 (e.g. A2-s1, d0).
Class E only has additional class d2.
Class F means that the product is not documented, the product does not meet the criteria for any class, or the manufacturer has not provided the fire properties for the product. Class F cannot be combined with any additional class either.
Fire classification of buildings
At the beginning of a construction project, during the planning phase, the designer must determine the operational and building technical class that the building must comply with. In many cases there is no alternative, but sometimes you can choose from multiple classes.
