Cylinders needs to be produced applying machines and processes adequate to make sure that each cylinder generated conforms to the requirements of this subpart.

S = Mc / I In which: S = Tensile stress in psi; M = Bending second in inch-lbs . (wl2/eight); I = Moment of inertia—0.04909 (D4−d4) in inches fourth; c = Radius (D/two) of cylinder in inches; w = Body weight per inch of cylinder full of drinking water; l = Duration of cylinder in inches; D = Exterior diameter in inches; d = Within diameter in inches.

(vi) Impression check specimens have to be cooled to the design services temperature. The apparatus for testing the specimens should conform to prerequisites of ASTM Standard E 23.
