6.3.2 Sootfire resistance When thermal testing takes place for sootfire resistance it shall be carried out at a test temperature of 1 000 °C for 30 min. 6.3.3 Resistance to fire 6.3.3.1 General The manufacturer shall declare the distance to combustible material, see 4.7. The distance shall satisfy the requirements given in 6.3.3.2 and 6.3.3.3 as appropriate. NOTE The manufacturer can declare a distance to combustible material that reflects installation practice in individual member states’ regulations. 6.3.3.2 Resistance to fire from internal to external resulting from normal operating conditions The maximum temperature of adjacent combustible materials shall not exceed 85 °C when related to an ambient temperature of 20 °C. The distance to combustible materials shall be verified by a test in accordance with prEN 1 321 6-1 for system chimneys or in the appropriate material dependent test standard to steady state at a test temperature given in Table 4 appropriate to the product designation. 6.3.3.3 Resistance to fire from internal to external resulting from sootfire conditions The maximum temperature of adjacent combustible materials shall not exceed 1 00 °C when related to an ambient temperature of 20 °C when tested at the test temperature of 1 000 °C over a period of 30 min. This distance to combustible material shall be verified by a test in accordance with prEN 1 321 6-1 for system chimneys or in the appropriate material dependent test standard. 6.3.3.4 Resistance to fire resulting from external to external The resistance to fire external to external shall be tested according to the relevant test standards for shafts and ducts (for classification of resistance to fire). 6.3.4 Reaction to fire In a chimney with plastic flue liners the manufacturer shall declare the reaction to fire class for the liner. 6.4.2 Water vapour diffusion resistance and condensate resistance 6.4.2.1 Chimneys operating under wet conditions The water vapour diffusion resistance and the condensate resistance shall be in accordance with the requirements of the relevant product standard. 6.4.2.2 Chimneys operating under dry conditions The water vapour diffusion resistance shall be in accordance with the requirements of the relevant product standard. 6.4.3 Corrosion resistance The effect of corrosion on the flue liner shall be in accordance with the requirements of the relevant product standard. 6.5 Safety in use Where accidental human contact is possible the maximum temperature of the outer surface of a chimney or of its enclosure shall be for an one second burn threshold in accordance with EN 563 when tested at the nominal working temperature appropriate to the product designation. 6.6 Energy economy and heat retention The thermal resistance of the chimney shall be determined by calculation or tests. 6.7 Additional criteria for chimney operation 6.7.1 Apertures for cleaning and inspection The doors of openings for cleaning or inspection shall be in accordance with the requirements of the relevant product standard. 6.7.2 Water penetration The ability to withstand weathering shall be in accordance with the requirements of the relevant product standard. 6.7.3 Aerodynamic properties of terminal Where special aerodynamic properties are claimed, the performance of the terminal shall be in accordance with the requirements of the relevant product standard. 6.7.4 Condensate collection and removal Chimneys operating normally under wet conditions shall have a facility to enable the collection and removal of the condensate which shall be in accordance with the requirements of the relevant product standard. 6.7.5 Flow resistance For the calculation of the pressure loss in a flue the mean value of roughness for the material of the flue and the coefficient of flow resistance due to a directional and/or cross sectional and/or mass flow change in the flue shall be determined. 6.3.1 Heat resistance When thermal testing takes place, it shall be carried out at the test temperatures under steady state conditions appropriate to the product designation given in Table 4. Steady state conditions are defined in the relevant material related test standards.EN 1443 pdf download.
