Hi all, I am some clarification on the equivalence of flame retardancy categories between UK and Europe. I have a product a client is hoping to use as a door covering, the product has a flame retardancy rating of B1. Having looked at various sources I am still not 100% certain of whether the two are equivalent or not. I am aware of the Building Reg requirements for the use of Class O wall covering, it is therefore a question of the European standard equivalents. Any assistance and preferably supporting documentation would be appreciated. Thanks Ade

BS EN13501-1 ­ Fire classification of construction products and building elements....Most popular wall coverings will fail at Class B which is supposed to be equivalent to BS Class 0. BS476 has therefore been retained for as long as it takes to resolve this issue...source BCFA.... BS 476: Part 22 Doors = BS EN 1634-1

Thanks Steve, Bit of a funny one I know, I will try the manufacturer for further info, the data sheet states, fire rated B1 which I believe is achieved in accordance with the German Bauregellisten (Building Regs List). I have found another document from Clear Construction which identifies B1 as an equivalent to class 0. I will keep looking for further evidence. Thanks again. Ade
