- Hardness Requirements:
- Brinell, Vickers, or Rockwell hardness tests shall be
made on specimens from two tubes from each lot.
- Flattening Test- One flattening test shall be made on specimens from each end of one finished tube, not the one used for the flaring test, from each lot.
- Flaring Test- _One flaring test shall be made on speci-mens from each end of one finished tube, not the one used for the fattening test, from each lot.
- Mechanical property requirements do not apply to tubing smaller than /8 in. [3.2 mm] in inside diameter or thinner than 0.015 in. [0.4 mm] in thickness.
