nominal height numerical designation of the height in millimetres of a standard flue block excluding any projecting spigot, which is a convenient round number NOTE For a bonding flue block, this is the co-ordinating height which equates to the nominal height of masonry building blocks for walls into which such a flue block is designed to be built.

nominal size numerical designation of size which is a convenient round number equal to or approximately equal to either:  the internal diameter in millimetres of flue blocks with circular section flue; or  the internal width in millimetres of flue blocks with square section flue; or  the internal width and breadth in millimetres of the internal transverse dimensions of flue blocks with rectangular section flue.

Flue blocks may be unglazed or glazed on the interior and/or exterior. When glazed, they need not be glazed on the jointing surfaces. 5.2 Insulation 5.2.1 General All information on reaction to fire shall be made available according to the relevant European product standard.

(1) where F is the minimum load in kN;
χ is the safety factor equal to 5;
H is the height of chimney in m;
G is the weight per metre in kg/m.

The flue block which forms part of a multi-wall chimney shall not be tested for the distance to combustible materials. The flue block that forms a chimney shall be tested for the distance to combustible materials. For the latter, the distance to combustible material shall be declared in accordance with 18.8. The manufacturer may declare a distance to combustible material that reflects installation practice in individual member states' regulations. The surface temperature of the combustible material shall be equal to or less than 100 °C for an ambient air temperature of 20 °C. NOTE This distance should not be less than the distance under normal operating conditions. 15.2 External to external For complete chimneys which convey products of combustion to the atmosphere, the resistance to fire external to external shall be evaluated according to the provision valid in the intended place of use of the flue blocks until a European test method is available. 16 Resistance to freeze/thaw When subject to regulation, the freeze/thaw resistance of the flue block shall be tested according to EN 14297. The product shall not present any damage of type 7, 8, 9 and 10 in accordance with EN 14297:2004, Table 1.

Isolated batches of units shall be assessed in accordance with tightened inspection procedures, with a maximum batch size of 1 200 (see Annex C). Batches rejected under the sampling procedure specified above may be resubmitted once, after removal of units with previously undetected visible defects, under the tightened inspection procedures, in respect only of the defect that caused initial rejection.
