Materials used shall be identified for factory production control purposes. NOTE 1 Additions may include glass or steel fibres. NOTE 2 Attention is drawn to Commission decision 96/603/EC, as amended, in which non-combustible masonry units containing not more than a mass or volume fraction of 1 % (whichever is the more onerous) of homogeneously distributed organic materials are classified as reaction to fire class A1 without testing. 4.2 Designations and classes 4.2.1 General Flue liners shall be designated according to clause 9. Designation classes for flue liners for temperature, pressure, resistance to soot fire, condensate resistance and corrosion resistance shall be according to 4.2.2 to 4.2.6. Abbreviated designations for common types of flue liners, according to temperature, pressure, soot fire resistance, and condensate resistance (wet or dry conditions) are given in Table 1 . Where a flue liner is manufactured for an application not covered by the abbreviated designations A to L the manufacturer shall declare the characteristics and appropriate designation in full as in clause 9.EN 1857 pdf download.
