EN 13403:2003 (E)6Emission of particles shall be less than 60 mg/m3 for particles bigger than 0,5 mm, and no more than 4 mg/m3 forparticles bigger than 5,0 mm.4.2 Resistance against pressure (without reinforcements)When tested in accordance with 7.3, air ducts and connector sections with joints, assembled in accordance with themanufacturer's instructions, shall withstand without rupture an internal air pressure of 2,5 times the manufacturer'srated positive pressure, but not less than 200 Pa.For this test rupture is considered as evidenced by breaks, tears, rips or other openings greater than 4 mm.NOTEPlastic deformation is not considered to be a ruptureAny joining material shall remain intact to the extent that materials such as tapes do not become displaced morethan a total for both edges of 4 mm from their initial position. There shall not be evidence of other damage, whichwould cause the sample to become unusable.4.3 Air

EN 13403:2003 (E)74.4 Bulging and/or caving, air leakageNo wall of the duct shall bulge and/or cave by more than 3 % of its width or 30 mm, whichever is the greater value.The maximum air leakage is defined at the relevant test pressure given in Table 3 based on relevant parts of thetest method described in prEN 1507.4.5 Supports and hangersThe ductwork shall fulfil the requirements specified in EN 12236.4.6 Facilities for cleaningThe ductwork shall conform to the requirements specified in ENV 12097. Different cleaning systems can be usedsuch as contact sucking, air pressure cleaning, or brushing and air pressure cleaning.When brushing is used brushes shall be non metallic (acrylic, nylon, etc.)The ductboard shall resist the cleaning operations equivalent to a life span of 20 years of use (one cleaningoperation per year) without any damage. When tested in accordance with 7.2, after 20 cleaning simulations havebeen performed, material from the inside surface of the ductwork shall not break away, flake off, or show evidenceof delamination or erosion.Emission of particles shall be less than 60 mg/m3 for particles bigger than 0,5 mm and no more than 4 mg/m3 forparticles bigger than 5 mm.4.7 Requirements for ductboards4.7.1 Health and safety The insulation materials used in the ductboards shall not be listed in the Directive 67/548/EEC Anne
