FIBCs of like design, manufactured using like materials and methods of construction (giving at least equal performance, to the same nominal cross-sectional dimensions
Note 1 to entry: Within a type, the design circumference dimension may be increased by 10 % by comparison with samples passing the type test, provided the same geometry is maintained. Where the FIBC type has a base-fitted discharge spout, a reduction of discharge spout diameter of the same design is permitted.
Note 2 to entry: The presence or absence of an inner liner does not constitute a change of type.
Note 3 to entry: Change of ultraviolet inhibitor, or the addition of anti-static agent, or the addition or change of pigment to a maximum of 3 % by mass, does not constitute a change of type.
FIBCs may be manufactured from a considerable variety of sheet and woven materials. The properties of the selected materials may be further modified by suitable additives, e.g. to improve the exposure life and strength and to reduce the effect of static electricity.
All materials of construction shall, after complete immersion in water for not less than 24 h, retain at least 85 % of the tensile strength measured after conditioning to equilibrium at 67 % relative humidity or less. The tensile strength should be measured by the method of test appropriate to the material used.
NOTE For example, ISO 13934-1 specifies tensile strength test requirements for tensile properties, seam tensile properties, tear properties and seam slippage for textile fabrics.
Protection against ultraviolet radiation shall be provided by the addition of carbon black or other suitable inhibitors. These additives shall be compatible with the materials to be carried in the FIBC.For polyolefins, the protection provided by a loading of 0.3 % by mass of an appropriate benzophenone shall represent the minimum ultraviolet stabilization required. Other types of ultraviolet stabilizers,such as benzotriazoles and hindered amines, may be employed, singly or in combinations, provided they exhibit similar protection to the benzophenone type stabilizers at the loading specified above.
For other materials sufficient ultraviolet stabilizers shall be added to the material to ensure ultraviolet resistance at least equal to that required for polyolefins.AS 3668 pdf free download.
