| a | 1 inch = 25.4 mm. |
| b | Flash-In tubing is produced only to outside diameter tolerances and wall thickness tolerances and the inside diameter welding flash does not exceed the wall thickness or 3/32 inch, whichever is less. |
| c | Flash controlled to 0.010 inch max tubing consists of tubing over 1-1/8 inch outside diameter which is commonly produced only to outside diameter tolerances and wall thickness tolerances, in which the height of the remaining inside welding flash is controlled not to exceed 0.010 inch |
| d | Flash controlled to 0.005 inch max tubing is produced to outside diameters and wall thickness tolerance, inside diameter and wall thickness tolerances, or outside diameter and inside diameter tolerances, in which the height of the remaining flash is controlled not to exceed 0.005 inch. Any remaining flash is considered to be part of the applicable inside diameter tolerances. |
| e | No-flash tubing is further processed for closer tolerances with mandrel-tubing produced to outside diameter and wall, inside diameter and wall, or outside diameter and inside diameter to tolerances with no dimensional indication of inside diameter flash. This condition is available in Types 5 and 6. |
| f | Birmingham Wire Gauge. |
| g | The ovality shall be within the above tolerances except when the wall thickness is less than 3 percent of the outside diameter, in such cases see 10.6.1. |
