1) s is the wail thickness of tube (see sub clause 5.5.5).
2) Average value from three tests; only one individual value may fall short of the specified minimum value by not more than 30 %
3) These values apply also if the impact energy is tested in the center of the weld for tubes having outside diameters exceeding 500 mm, and wall thicknesses not smaller than 10mm.
4) For cold finished tubes in the NBK condition (annealed above the upper transformation point under shielding gas or in a vacuum), minimum values of yield stress lower than these values by 20N/mm2 are permitted.
5) For cold finished in the NBK condition, minimum values of tensile strength lower than these values by 10N/mm2 are permitted.
