Minimum required thickness without corrosion allowance, based on the mechanical loads other than pressure that result in longitudinal stress. See 7.6.
- NOTE: The thickness is either determined from a standard chart or engineering calculations. It does not include thickness for corrosion allowance or mill tolerances.
