| These permissible variations in length apply to tubes before bending. They apply to cut lengths up to and including 24 ft [7.3 m]. 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. | ||
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.

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.
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.
Orders for ASTM A210 / A210M, ASME SA210 should include the following, as required, to describe the desired material adequately:
Apply to Boiler Tubes, Seamless Steel Tubes, Steel Tubes, and Superheater Tubes.
Packed in wooden box or bundles protected with plastic paper, and suitably protected for sea-worthily delivery or as requested.
The Product marking shall include the ASTM A210 or ASME SA210, size, heat no., Lot No. and Manufacture name or logo.
