Fire testing with SBI (Single burning Item) EN 13823
The test specimens, short wing 495 mm × 1500 mm and long wing 1000 mm × 1500 mm, are fixed cornerwise in the specimen holder of the test apparatus.
The test specimens shall be mounted as in their end-use application because mounting and fixing of the test specimen may have an effect on the test results and influence on the field of application of test results and validity of classification. Some facts that shall be taken into account when planning the test specimens are: substrate, fixings, joints, edges, air gaps, product direction and geometry.
A propane gas burner with a thermal output of 30 kW is placed at the bottom of the corner. The test specimen and the burner are located under a hood in an enclosure.
During the test, heat release (FIGRA, THR600s) and smoke production (SMOGRA, TSP600s) are measured. Lateral flame spread (LFS) and the formation of burning droplets/particles are observed visually.
The test method is used for classification of construction products, except flooring materials, to Euroclasses A1, A2, B, C and D as well as A2L, BL, CL and DL. The classification is not only based on the SBI-results. Different test methods and classification criteria are presented in the classification standard EN 13501-1+A1.
