Nominal sizes: The nominal sizes of the tubes range from 6mm to 200mm, with wall thicknesses from 0.5mm to 10mm. 2. Dimensions: The standard specifies the dimensions of the tubes, including the outside diameter, wall thickness, and length. The outside diameter of the tubes ranges from 6mm to 200mm, with a tolerance of +/- 0.08mm. The wall thickness ranges from 0.5mm to 10mm, with a tolerance of +/- 10%. 3. Ovality: The standard specifies the ovality of the tubes, which is the difference between the maximum and minimum diameter of the tube divided by the nominal diameter. The ovality tolerance ranges from 0.4% to 1.0%, depending on the diameter and wall thickness of the tube. 4. Straightness: The standard specifies the straightness of the tubes, which is the maximum deviation from a straight line over the length of the tube. The straightness tolerance ranges from 0.15% to 0.25% depending on the diameter and wall thickness of the tube. 5. Length: The standard specifies the length of the tubes, which can be cut to specific lengths or supplied in random lengths. The tolerance on length is +/- 500mm or +/- 3% of the total length, whichever is greater. 6. Surface finish: The standard specifies the surface finish of the tubes, which must be free from defects and have a smooth, clean surface. In summary, the EN 10305-3 standard defines the sizes and diameter tolerances for welded cold-sized steel tubes for precision applications, including nominal sizes, dimensions, ovality, straightness, length, and surface finish.
