For lengths greater than 24 ft [7.3 m], the above over-tolerances shall be increased by 1⁄8 in. [3 mm] for each 10 ft [3 m] or fraction thereof over 24 ft or 1⁄2 in. [13 mm], whichever is the lesser. | ||
ASTM A210 / A210M Tube Hydrostatic Test Pressures
Each tube shall be subjected to the hydrostatic pressure test, or instead of this test, a nondestructive test may be used when specified by the purchaser.

| 2 to 3 [50.8 to 76.2], excl | 2500 [17] |
ASTM A210 / A210M Flattening Test
One flattening test shall be made on specimens from each end of one finished tube from each lot, but not the one used for the flaring test. Tears or breaks occurring at the 12 or 6 o’clock positions on Grade C tubing with sizes of 2.375 in. [60.3 mm] in outside diameter and smaller shall not be considered a basis for rejection.
ASTM A210 / A210M Flaring Test
One flaring test shall be made on specie- men from each end of the one finished tube from each lot, but not the one used for the flattening test.
