and insert the following text and note: ‘There are four main types of clay/ceramic flue liner
dependent on working temperature, with sub-types dependent on whether the flue liners
are to be used in chimneys designed to work under negative or positive pressure, or are
to have soot fire resistance. The types, working temperatures, test pressures and
maximum air permeability rates are given in Table 1. The suitability of each type of flue
liner to be used in chimneys designed to operate under negative or positive pressure and
wet or dry conditions is also given.
NOTE A flue liner can be designated in one or more types provided that it complies with the appropriate
requirements for each type.”

15.Evaluation of conformity
15.1 Initial type testing
Type tests relating to material composition shall be performed initially together with factory production
control tests as given in Table 5. One test shall be carried for each requirement.
The thermal testing shall be carried out on one size of flue liner for each geometrical configuration e.g.
circular, square, rectangular. For circular flue liners the size to be tested shall be 200 mm ± 50 mm
internal diameter. For other geometrical configurations the flue liner shall have an equivalent cross-
sectional area range.
15.2 Further type tests
Type tests shall be performed when a change is made either in material composition, processing
technique or to the design or method of manufacture of the flue liner, but they may be performed more
frequently by incorporation into a plan for monitoring the consistency of manufacture (see Table 5).

(1) The tests carried out during FPC are intended to verify that the performance
requirements assessed through the initial type testing are maintained.
15.3 Factory production control
To achieve compliance with this standard the manufacturer shall establish and maintain an effective
documented quality system.
Factory production control tests are carried out following manufacture to monitor the quality of product
(see Table 5).
Sampling and testing of any batch shall be completed prior to removal from the works and shall be in
accordance with ISO 2859-1 at an AQL of 10 % and inspection level S2. Isolated batches of units shall
be assessed in accordance with tightened inspection procedures, with a maximum batch size of 1 200
(see annex A).
Batches rejected under the factory production control procedure 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.
NOTE A quality system assessed by a certification body which complies with the requirements of EN 45012 can
be applied to ensure that the requirements of ISO EN 9002 and clause 15 are complied with.”
