Amendment 1 – Wind energy generation systems – Part 5: Wind turbine blades

PROPOSED STABILITY DATE: 2026

NOTE FROM TC/SC OFFICERS:
At the IEC TC 88 meeting held in Jeju Island, Korea the following decision was taken:

Decision 2(6): The option to go from NP with a CD attached directly to CDV stage shall not be used except in limited cases,
with explicit permission from the TC 88 officers. The intention to go from NP to CDV shall be indicated on the NP form.

The TC 88 Officers have on basis of this action taken the decision, that the CD stage will be skipped for the following reasons:

• The existing Maintenance Team (MT 5) has broad NC participation
• All MT 5 experts have had possibility to comment/be involved in the work
• The amendment does not contain any controversial items
