Information about EN 13823 - Single burning item (SBI)Test method EN 13823 – SBI, fire technical testing of building products.
Main field of application
Building products, except for flooring materials, are exposed to thermal heat from a gas burner.
Classification according to Euroclass A1, A2, B, C, or D according to the European System. Also additional test methods are used, see data sheet EN ISO 1182, EN ISO 1726 and EN ISO 11925-2.
Declaration of a products fire characteristics for specific purposes, for example insurance purposes.
In the test method, the products heat release rate (kW), total heat release (MJ) and smoke production rate (m2/s) are measured. Flame spread and burning droplets/particles are observed visually.
Examples of products that can be tested with this method
All types of building products, for example those included in the European Construction Product Regulation, CPR, or found in national regulations, for example wallpaper, paint systems, acoustic boards and coverings.
Material consumption during test
|5 test samples with the dimension 1.00 m x 1.50 m (long wing) and 5 samples with the dimension 0.49 m x 1.50 m (short wing)|
|1 test sample with the dimension 1.00 m x 1.50 m (long wing and 1 sample with the dimension 0.49 m x 1.50 m (short wing)|
To think about
The mounting of the sample should be as close to reality as possible. If there are vertical and/or horizontal joints in end use, these joints should also occur on the test panel. It is important to decide which substrate the product shall be applied to and how the product shall be mounted. Possible air gaps or similar shall be considered.
A large and a small wing are mounted in a right angle and create a corner. A gas burner with a heat release rate of 30 kW is located in the corner during testing. The test time is 21 minutes. The combustion gases are collected through a hood where heat release rate and smoke production are measured (see figure above).
Reference method for EN 13823 – SBI is the full-scale method EN 14390 – Room corner. Test according to ISO 5660 - Cone Calorimeter could be performed to predict expected test results in EN 13823 – SBI.
