2.2.2European fire classifications

Classification of HPL and HPL-Compact without further testing

HPL, type S/P and HPL-Compact, type CGS have a CWFT classification of Euroclass D-s2, d0 (CWFT = classification without further testing). The CWFT classification was published in the Official Journal of the European Union (L201/25 dated 8-8-2003).

HPL ≥ 0.5 mm

D-s2, d0
(1) Either fastened directly (e.g. without air gap) onto a material of Euroclass A2-s1, d0 or better and with a bulk density of ≥ 600 kg/m3 or mounted on a wooden or metal frame, with an unventilated (e.g. opening only to the top) gap of at least 30 mm, the reverse of the hollow space must be designed to have a reaction to fire classification of A2-s2, d0 or better
(2) Classes intended as per table 1 of the appendix to the decision of the Commission 2000/147/EG
(3) As per standard EN 438-7
