7.3 Squareness of ends When the deviation of the squareness of ends is tested in accordance with either procedure described in A.3 the flue liner shall not touch the upright for the first procedure and the dimension "G" shall not be greater than 5 mm for the second procedure.
8 Performance requirements 8.1 Heat stress resistance 8.1.1 When a flue liner is tested in accordance with A.4 to the test temperature appropriate to the flue liner designation given in Table 1, the flue liner shall subsequently conform to the requirements of 8.3.
The thermal testing shall be carried out on one size of flue liner for each geometrical configuration, e.g. circular, rectangular, square, also for each material mix, method of manufacture and wall thickness. For circular flue liners the size to be tested shall be (200 ± 50) mm internal transverse dimension. For other geometrical configurations the flue liner shall have an equivalent cross-sectional area.
