If direct measurement is to be carried out, two measurements should be taken at the observed maximum and minimum diameters. The test also can be carried out using two gauges whose diameters are set at the minimum and maximum diameters. The minimum gauge should be able to be turned through 360° within the whole length of the flue liner. The maximum gauge should not be able to enter the flue liner when turned through a rotation of 360°. For square and rectangular flue liners, the internal transverse dimensions shall be measured between the mid points of opposite sides of the flue liner. A.1.2 Declared height The maximum and minimum declared heights of a flue liner shall be those calculated from the manufacturer's declared dimensions and the tolerances specified in 7.1. If direct measurement is to be carried out, two measurements should be taken at the observed maximum and minimum internal heights. The test can also be carried out by using two gauges whose heights are set at the minimum and maximum internal heights. The minimum gauge should not be able to fit over the internal height of the flue liner. The maximum gauge should be able to fit over the internal height of the flue liner. A.1.3 Wall thickness The maximum and minimum wall thickness dimensions shall be those calculated from the manufacturer's declared dimensions and the tolerances specified in 7.1 or direct measurement is to be carried out at the observed maximum and minimum thickness.
