AThese permissible variations in length apply to tube in straight lengths.

They apply to cut lengths up to and including 24 ft(7.3 m). For lengths over 24 ft an additional over-tolerance of 1/8 in. (3.2 mm) for each 10 ft (3.0 m) or fraction there of shall be permissible up to a maximum additional over-tolerance of 1/2 in. (12.7 mm). NOTE 3 - For tension, hardness, flare flattening, and flare test requirements, the term lot applies to all lengths prior to cutting.
