scope:

This European Standard specifies the requirements and test methods for multiwall soot fire resistant system chimneys, working under dry conditions, with corrosion resistance 3, with negative pressure (see EN 1443) in which the products of combustion are conveyed to the atmosphere through clay/ceramic flue liners. Marking and inspection are also covered by this standard. This standard does not apply to structurally independent (free standing or self-supporting) system chimneys. A soot fire resistant system chimney has the following items where appropriate: - clay/ceramic flue liners; - Insulation layer; - outer walls; - mortar for jointing flue liners; - mortar for jointing outer walls; - terminal; - chimney base; - cladding; - opening section; - cleaning and inspection door; - distance piece; - reinforcement. The soot fire resistant chimney covers a combination of compatible chimney components, obtained or specified from one manufacturing source with product responsibility for the whole chimney.
