4 Requirements for the liner
4.1 General
The liner is formed by brickwork using clay/ceramic bricks according to 5.1 and mortar according to 5.2. It shall be
designed in accordance with EN 13084-4 and shall be erected according to the state of the art. Dependent on the
brick and mortar types used the brickwork is classified in accordance with EN 13084-4: 2005, 4.2.3 (see also Table
1).

BT1 A (A) very high
BT2 B high
BT3 C medium
BT4 D low
BT5 E no chemical attack

only if the very high chemical attack is due only to acids
4.2 Performance characteristics
4.2.1 General
The characteristics specified in 4.2 presume an execution of the liner in accordance with EN 13084-4.
4.2.2 Mechanical resistance and stability
Mechanical resistance and stability shall be verified according to EN 13084-4 taking into account characteristic
values of compressive and flexural strength for the different brickwork classes which are specified in EN 13084-4:
2005, Table 3 or are determined by tests in accordance with EN 1052-1 and EN 1052-2 respectively.

4.2.3 Compressive strength
In order to meet this requirement the bricks shall comply with the respective values given in Table 2 and the mortar
with the values given in Table 4.
4.2.4 Flexural tensile strength
In order to meet this requirement the bricks shall comply with the respective values given in Table 2 and the mortar
with the values for initial shear strength in accordance with Table 4.
4.2.5 Resistance to fire
Soot fire resistance shall only be verified for brick liners conveying flue gas of solid combustibles and whose inner
diameter in the case of circular section or smallest inner lateral length in the case of rectangular section is less than
1,0 m.
In this case EN 1443: 2003, 6.3.2 applies.
For liners different from the above mentioned ones the verification of soot fire resistance may be omitted. This also
applies to liners for chimneys with an upstream flue gas treatment.
Limit values of permissible temperatures for bricks and mortars shall be declared by the manufacturer.
4.2.6 Gas tightness
En 13084-1: 2000, 4.2.4 specifies that in a brickwork liner positive internal pressure shall only be allowed in a short-
term or exceptional situation. It is not allowed during normal operation conditions. The state of the art has shown,
that gas tightness may not be required.
4.2.7 Flow resistance
A mean roughness value for brickwork liners to carry out flow calculations is given in EN 13084-1: 2000, Table A.3.
4.2.8 Dimensioning/ Thermal resistance
Heat flow calculations shall be carried out according to EN 13084-1: 2000, 4.2.3. Thermal resistance shall be
calculated according to EN 13084-1: 2000, A.2.2 using the values of thermal conductivity specified in EN 13084-1:
2000, Table 1.
4.2.9 Thermal shock resistance
This requirement is met by testing successfully the bricks and mortar for resistance to temperature change
according to Table 2 and Table 4 respectively.
4.2.10 Resistance to freeze-thaw
Resistance to freeze-thaw shall only be required for bricks and mortar used in parts of the liner near the mouth of
the chimney. The requirement is met by testing successfully the bricks according to 6.1.9. For mortar see 6.2.8.
4.2.11 Durability
Durability to chemical attack is verified by classifying brickwork (bricks and mortar) in accordance with EN 13084-4:
2005, 4.2.3 and Table 1 of this standard dependent on the degree of chemical attack (see also EN 13084-1: 2000,
Table 3).
5 Materials
5.1 Bricks
5.1.1 General
Bricks may be of plain rectangular shape or they may be profiled to develop shear keys in the mortar, or to accept
metal reinforcement.
The requirements for bricks are given in Table 2 and Table 3.
The surface of bricks should be free of cracks.
Smaller cracks (microcracks) shall not exceed the following values:
Crack width ≤ 0,05 mm;
Crack length ≤ 10 mm;
Crack depth ≤ 2 mm.
5.1.2 Bricks Type BT1
Bricks type BT1 are suitable for brickwork resistant to "very high chemical attack" due to acids and alkalis.
Attention shall be paid to their sensitivity to thermal shocks.
5.1.3 Bricks Type BT2 (a) and BT2 (b)
Bricks type BT2 (a) and BT2 (b) are suitable for brickwork resistant to "high chemical attack" in the presence of
acids or alkalis.
The chemical resistance of bricks type BT2 (a) derives from the properties of their ingredients, whereas type BT2
(b) d
