The adaptors shall be supplied by the chimney manufacturer and shall transfer the test load in the usual way to the load bearing wall of the test components as it is done in the installation. The test load shall be transferred to the test components by means of a pivoted plate. 4.1.1.2 Procedure and results Increase the test load on the components without shock up to 4 times the design load where the flue liner is load bearing or 3 times the design load where the flue liner is non load bearing. The load shall be measured to an accuracy of 2 % of the design load. Record the result. Where the design load is unknown, increase the test load uniformly and record the results to allow the point of failure to be detected. Failure is deemed to have occurred when the fitting cannot sustain a further increase in load. Use the minimum value from three failure loads to determine the design load. SIST EN 1859:2009

Where the design load is unknown, increase the load uniformly and record the results to allow the point of failure to be detected. Failure is deemed to have occurred when the support cannot sustain a further increase in load. Record the displacement during the load increase. Use the minimum value from three failure loads to determine the design load. 4.2 Tensile strength 4.2.1 Test assembly Install the chimney sections according to the manufacturer's installation instructions. Apply the test load through an adaptor (see Figure 1c). The adaptor shall be supplied by the chimney manufacturer and shall transfer the test load in the usual way to the load bearing wall of the chimney sections. 4.2.2 Test procedure and results Increase the test load on the components without shock up to 1,5 times the design load. The load shall be measured to an accuracy of 2 % of the design load. Record the result. Where the design load is unknown, increase the test load uniformly and record the results to allow the point of failure to be detected. Failure is deemed to have occurred when the fitting cannot sustain a further increase in load. Use the minimum value from three failure loads to determine the design load. 4.3 Lateral strength 4.3.1 Fittings in non-vertical orientation 4.3.1.1 Test assembly Install the chimney fittings and supports at the maximum angle from vertical according to the manufacturer's installation instructions using additional vertical supports to install the sections without deflection (see Figure 2). SIST EN 1859:2009

The chimney shall be tested according to Figure 5. NOTE Figure 6 shows the arrangement for testing off-sets. 4.5.1.2 Test structure 4.5.1.2.1 General Construct a test structure consisting of two walls at right angles and two floors through which the test chimney passes, of construction as described in 4.5.1.2.2 and 4.5.1.2.3 or of equivalent thermal characteristics and dimensions. The floor opening and wall position shall enable the test chimney to be erected so that all parts of the test structure are at the manufacturer's specified clearance X mm from the chimney. The area below the first floor referenced as Zone A, the area between the first floor and second floor as Zone B, and the area above the second floor as Zone C, as shown in Figure 5. The wall/floor interface shall be fitted with nominally 20 mm x 100 mm skirting board. The vertical distance between the floor and ceiling in Zone B shall be (2 400 ± 25) mm. The height of the chimney protruding into Zone C shall not be less than 900 mm. Timbers shall have a dimensional tolerance of ± 1 mm. 4.5.1.2.2 Walls Construct walls consisting of nominal dimension 38 mm x 89 mm thick timbers in a framework (see Figure 5) faced on each side with one layer of nominally 12 mm thick plywood to give a total thickness of 113 mm ± 1 mm, insulated in the voids with mineral fibre insulant having a thermal conductivity of 0,035 W/m K ± 0,002 W/m K at 20 °C with a minimum density of 70 kg/m3. The walls shall extend at least 1 200 mm. 4.5.1.2.3 Floors Construct flooring framework of nominal dimension 50 mm x 200 mm timbers at the first floor level and nominal dimension 50 mm x 100 mm timbers at the second floor level forming an opening that enables the test chimney to be erected so that all parts of the test structure comply with the manufacturer's declared minimum distance to combustible material from the chimney fittings (see Figure 5) and covered with one thickness of nominal dimension 20 mm boarding for the floors and one thickness of nominal dimension 12 mm plywood for the ceilings, except for the second floor ceiling (exposed top), and the spaces between the timbers filled with 100 mm thick mineral wool slab with a thermal conductivity of 0,035 W/m K ± 0,002 W/m K at 20 °C, with a minimum density of 70 kg/m3. 4.5.1.3 Test chimney Construct the test chimney using the components materials and construction representing the manufacturer's product range, including a termination, and, at least 7 joints. Assemble the chimney in accordance with the manufacturer's installation instructions, including firestops or firestops and spacers to a height of not less than 4,5 m, including base support components, if used. Construct the test chimney according to Figure 5 for all sections, T pieces and inspection openings. Where a manufacturer’s product range includes bends, the test chimney shall include one offset (see Figure 6), with an offset angle of maximum 45° and an offset distance of 0.75 m ± 0.25 m. Any inspection opening shall be in Zone C
Include any finishing (e.g. non-combustible enclosures or claddings) specified in the manufacturer's instructions. SIST EN 1859:2009

through a 150 mm ± 2 mm length of stainless steel tubing, internal diameter
3mm10mmmm+ inserted through the flue pipe and flush with the flue surface and sealed by brazing, at a distance of 100 mm ± 2 mm from the entry to the test chimney. SIST EN 1859:2009

Seal only joints and openings between spacers or supports and the test structure and all joints in the enclosure casing. Install a chimney designated for use without an enclosure into the test structure, without enclosing the test chimney and without closing the floor penetrations (see Figure 7). SIST EN 1859:2009

Maintain this condition for 10 min, then shut off the hot gas generator and allow to cool for 10 min. Repeat this cycle 11 times. Measure, at ambient temperature, with an accuracy of 0.001 m, the change in vertical position of the chimney wall(s) at the top of the test sample before and after subjecting the product to the cycles. Measure and record the gas tightness according to 4.4. 4.5.3.2 Thermal shock test With the test assembly temperatures within 10 °C of the test room ambient conditions generate hot gas with the volume flow and test temperature specified in Table 1 appropriate to the diameter. Regulate the rate of rise of the hot gas temperature to achieve 1000 °C in 10 min ± 1 min. Maintain the hot gas temperature at 10005020+− °C for a period of 30 min ± 1 min, then turn off the hot gas generator. Continue to record the temperatures on the test assembly until the temperatures have reached their maximum and are decreasing. Measure and record flue regularity and measure gas tightness according to 4.4. SIST EN 1859:2009
