The Single-Flame Source Test


The test is required as part of the European construction products directive classification of reaction to fire performance for wall and roofing products and floor- coverings.“The Single Flame Source Test” (Ignitability Apparatus) is built in accordance with EN ISO 11925-2.


EN ISO 11925-2: Reaction to fire tests – Ignitability of building products subjected to direct impingement of flame – Part 2: Single-flame source test.


Full classification and performance criteria can be found in a separate FTT document “New European Fire Testing Classification for Construction Products.”


Product Classification


The European Construction Products Directive classification criteria for all building products, has performance classes from A-F.Although other tests are required for assessment, the single flame source apparatus is needed for qualifying all types of construction products to classes B, C, D and E.The classification criteria for each product group are shown in the tables below.


Classification for construction products excluding floorings CLASS CLASSIFICATION CRITERIA BFs CFs DFs EFs
