式中：
A——拉伸试样横截面积，对全截面试样，取485mm2和采用钢管规定外径和规定壁厚计算的试样横截面积两者中的较小者；
U——规定抗拉强度的最小值，MPa。
Where
A——tensile test specimen area，for full section specimens, the smaller of 485 mm2 and the cross-sectional area of the test specimen, calculated using the specified outside diameter and the specified wall thickness of the pipe.
U——specified minimum ultimate tensile strength, MPa.

a.当碳当量小于或等于0.12%时，碳当量应采用下列PE（Pcm）公式计算
b. 当碳当量大于0.12%时，碳当量应采用下列CE（IIW）公式计算
Note: For PSL2 pipe, carbon equivalent (CE) calculations shall be based on the product analyses and shall be calculated as follow.
a. When the carbon content is less than or equal to 0.12%, the carbon equivalent shall be calculated using the following formula for CE (Pcm):
b. When the carbon content is greater than 0.12%, the carbon equivalent shall be calculated using the following formula for CE (IIW):
