17、EN 1443:2003 and EN 1856-1:2009 apply. 4 Test methods for metal chimney products 4.1 Compressive strength 4.1.1 Sections and Fittings 4.1.1.1 Test assembly Assemble the fitting according to the manufacturers installation instructions between two adaptors including one chimney section (see Figure 1a)
18、. 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 a
19、nd 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
20、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. -
21、- EN 1859:2009 (E) 6 4.1.2 Chimney support 4.1.2.1 Test assembly Install the chimney support according to the manufacturers installation instructions. Apply the test load to the chimney support through a chimney section and an adaptor (see Figure 1b). The adaptor shall be supplied by the chimney man
22、ufacturer and shall transfer the test load in the usual way to the load bearing wall of the chimney sections. The test load shall be transferred to the test component by means of a pivoted plate. 4.1.2.2 Procedure and results Increase the test load up to the design load without shock. Record the max
23、imum displacement of the chimney. Measure the displacement to an accuracy of 0,1 mm. Further increase the load up to 3 times the design load. Record the results. Measure the load to an accuracy of 2 % of the design load. Where the design load is unknown, increase the load uniformly and record the re
24、sults 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
25、 Test assembly Install the chimney sections according to the manufacturers 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 ch
26、imney 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 reco
27、rd 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
28、.1.1 Test assembly Install the chimney fittings and supports at the maximum angle from vertical according to the manufacturers installation instructions using additional vertical supports to install the sections without deflection (see Figure 2). - - EN 1859:2009 (E) 7 4.3.1.2 Procedure and results
29、Remove the additional vertical supports. Record the maximum deflection to an accuracy of 0,1 mm. 4.3.2 Wind load 4.3.2.1 Test assembly Install the chimney components according to the manufacturers installation instructions. Use the test assembly consisting of the manufacturers declared freestanding
30、components and further chimney sections up to the manufacturers maximum declared lateral support separation distance between the supports, and once again the same distance up to an anchor point (see Figure 3). 4.3.2.2 Procedure and results Apply an evenly distributed test load increased uniformly up
31、 to 1,5 kN/m2 2,5 %. NOTE A method for applying an evenly distributed load is described in informative Annex G. Other methods using a vertical assembly may also be used. Apply the test load to those components declared by the manufacturer for external use, except 50 % of the last laterally supported
32、 section of the test assembly. Apply the test load by a number of individual evenly distributed loads equally spaced from the freestanding end at not more than (0,2 0,01) m intervals. The individual loads shall not vary by more than 1 %. Record the results. 4.4 Gas tightness 4.4.1 Test assembly Cons
33、truct the test assembly as described in 4.5. Seal the test assembly chimney flue outlet with an air tight seal. Use adaptors supplied by the manufacturer in order to ensure that the chimney inlet and outlet are closed in a typical manner. Connect a positive pressure air supply and flow meter to the
34、test chimney flue inlet with appropriate air tight seals. Connect a manometer to the flue of the test assembly (see Figure 4). 4.4.2 Procedure and results The test shall be carried out at ambient temperature. Deliver air from the air supply to the flue at a rate necessary to achieve and maintain the
35、 required test pressure given in Table 1 of EN 1856-1:2009. Measure the test pressure and the air flow rate, both to an accuracy of 5,0 %. Record the air flow rate. 4.5 Thermal performance test 4.5.1 Apparatus The test assembly shall comprise a test structure (see 4.5.1.2), a test chimney (see 4.5.1
