BS 1857:2010 pdf download – Chimneys — Components — Concrete flue liners 1 Scope This European Standard specifies the material, dimensional and performance requirements, including methods oftest,for precast concrete flue liners and fittings with or without insulation for the construction of multi-wallchimneys. This document does not cover: — high positive pressure (H) designated products; – products designated wet (w) in conjunction with corrosion class 3. This document also applies to storey-height and flue liners reinforced only for handling. NOTE1 Any reference to the term flue liners implies both fue liners and their fittings, except where otherwiseindicated. NOTE2 The pressure classes and corrosion classes are defined in EN 1443. 2Normative references The following referenced documents are indispensable for the application of this document.For datedreferences,only the edition cited applies.For undated references,the latest edition of the referenceddocument (including any amendments) applies.
