| AApplies to specified wall thicknesses (t) equal to or greater than 0.120 in. (3.05 mm). For lighter specified wall thicknesses, the minimum elongation values shall be calculated by the formula: percent elongation in 2 in. (50mm) = 56t + 17.5, rounded to the nearest percent. For A500M use the following formula: 2.2t + 17.5, rounded to the nearest percent. BApplies to specified wall thicknesses (t) equal to or greater than 0.180 in. (4.57 mm). For lighter specified wall thicknesses, the minimum elongation values shall be calculated by the formula: percent elongation in 2 in. (50 mm) = 61t + 12, rounded to the nearest percent. For A500M use the following formula: 2.4t + 12, rounded to the nearest percent. CApplies to specified wall thicknesses (t) equal to or greater than 0.120 in. (3.05 mm). For lighter specified wall thicknesses, the minimum elongation values shall be by agreement with the manufacturer. DThe minimum elongation values specified apply only to tests performed prior to shipment of the tubing. |

Permissible variations in outside diameter
For round structural tubing with outside diameters of 1.900" and smaller: Outside diameter shall not vary more than +/- 5% from specified outside diameter.
For square and rectangular tubing, see the chart below:
| Specified outside large flat dimension, in. (mm) | Permissible variations over and under specified outside flat dimensionsA, in. (mm) |
| 2.5 (65) or under | 0.020 (0.5) |
| Over 2.5 to 3.5 (65 to 90), incl | 0.025 (0.6) |
| Over 3.5 to 5.5 (90 to 140), incl | 0.030 (0.8) |
| Over 5.5 (140) | 0.01 times large flat dimension |
| AThe permissible variations include allowances for convexity and concavity. For rectangular tubing having a ratio of outside large to small flat dimension less than 1.5, and for square tubing, the permissible variations in small flat dimension shall be identical to the permissible variations in large flat dimension. For rectangular tubing having a ratio of outside large to small flat dimension in the range of 1.5 to 3.0 inclusive, the permissible variations in small flat dimension shall be 1.5 times the permissible variations in large flat dimension. For rectangular tubing having a ratio of outside large to small flat dimension greater than 3.0, the permissive variations in small flat dimension shall be 2.0 times the permissible variations in large flat dimension. | |
