CEN/TC 297/WG 4 - Linings

This European Standard specifies performance requirements and test methods for clay/ceramic bricks and factory made mortars used for the construction of brick liners in free-standing industrial chimneys. The structural design of the brick liners is specified in EN 13084-4.
The marking requirement for bricks and mortar covered by this European Standard is included. This European Standard provides for the evaluation of conformity of material for brick liners to this European Standard.

This European Standard specifies special requirements and performance criteria for the design and construction of lining systems made of brickwork for free-standing industrial chimneys. Current European practice favours sectional liners and the statements of the standard are mainly devoted to such solutions but are also largely applicable to base supported independent and stayed liners. The differences in the design and construction of the two last types are covered by Annex A. This European Standard identifies requirements to ensure mechanical resistance and stability of liners in accordance with the general requirements given in EN 13084-1.
Lining systems comprise some or all of the following:
chimney liner including duct entry;
insulation;
liner support;
space between liner and concrete windshield.
Gas flow calculations to determine liner sizes are covered by EN 13084-1.

This European standard deals with special requirements and performance criteria for the design and construction of lining systems made of brickwork for free-standing industrial chimneys. Current European practice favours sectional liners and the statements of the standard are mainly devoted to such solutions but are also largely applicable to independent and base supported liners. The differences in the design and construction of the two last types are covered in Annex C.
