Specifies requirments and laboratory test methods for the strength and air leakage testing of circular ducts. The objective is to establish the mechanical strength and leakage of a circular duct including the joints, in order to verify the fitnes for the intended use, transport and installation included. This standard is applicable to circular ducts used in ventilation and air conditioning systems in building for human occupancy. The standard primarily refers to ducts manufactured from steel, but is also applicable to rigid ducts made from other metallic materials, for example, aluminium and copper. The following characteristics are tested or inspected: - The maximum deflection at the centre of the duct installed on four test supports and loaded. - The air leakage of the duct. - Damage to the duct after loading. All of these characteristics are measured with the duct subjected topositive and negative pressures.
