What are Euroclasses?
Under the Construction Products Directive, there is a move towards European harmonisation of standards for fire retardant treatment of timber – Euroclasses B & C. To meet Euroclass B or C Specifications, timber/plywood is tested to EN ISO 11925 (Ignitability Test) & BS EN 13823:2002 (SBI or Single Burning Item Test). The SBI test records parameters relating to the rate of fire growth, lateral flame spread and total heat release.
