A construction product's Euroclass is assembled from specific instruments: the single flame source test for ignitability, the SBI for fire growth (FIGRA) and smoke, the non-combustibility furnace and bomb calorimeter for the A1/A2 evidence pair, and the flooring radiant panel for floorings. Laboratories equipping for CPR work usually plan these together; the construction sector page shows how the classification routes combine them.
