Note A: For tubing smaller than 1/2 in. [12.7 mm] in outside
diameter, the elongation values given for strip specimens in table
shall apply. Mechanical property requirements do not apply to tubing
smaller than 1/8 in. [3.2 mm] in outside diameter or with
walls thinner than 0.015 in. [0.4 mm]Note B: For longitudinal strip tests a deduction of 0.90 % for TP446–1 and
S 44735 and 1.00 % for all other grades shall be made from the basic
minimum elongation for each 1/32 in. [0.8 mm] decrease in
wall thickness below 5/16 in. [8 mm]. The following table
gives the computed minimum values
