Wind Tower Standards-to-Stage Compliance Checklist

Pick a target market and see which welding, NDT, coating and structural standards a wind tower production line must satisfy at each stage. Use it to brief a tender or audit a supplier.

Reference list, not legal advice. EN 1090-2 execution class EXC3 applies to fatigue-loaded wind towers (not EXC4); DNV-ST-0126 covers both onshore and offshore support structures. Confirm the exact edition and project scope with your certifying body.
