Rockwell hardness values shall only apply to: (a) tubes having a wall thickness of 0.012 in. (0.305 mm) or greater; (b) round tube having an inside diameter of ⁄16
in. (7.94 mm) or greater; and (c) rectangular and square tube having an inside major distance between parallel surfaces of ⁄4 in. (4.76 mm) or greater. Rockwell hardness
tests shall be made on the inside surface of the tube, and the value of the Rockwell hardness number of each specimen shall be established by taking the arithmetical
average of at least three readings. When suitable equipment is not available for determining the specified Rockwell hardness, other Rockwell scales and values may be
specified subject to agreement between the manufacturer and the purchaser.

Tube welded from cold-rolled strip can be regularly supplied by welding standard strip tempers and shall have mechanical properties as agreed upon between the
purchaser and the supplier.
