Should the US TAG approve the proposal from MT 12-1 and PT 61400-12-2 to divide the existing publication IEC 61400-12-1 Ed. 2 and IEC 61400-12-2 Ed. 1 into nine separate documents and separate out the wind measurement requirements from the power performance testing requirements?

Description

BACKGROUND
At the 2016 TC 88 meeting in Jeju, South Korea, the proposed re-structure of the IEC 61400-12-1 ED2 and IEC 61400-12-2 ED1 standards into separate documents covering wind measurement and power performance testing was presented.
The purpose of the re-structure was to allow the future management and revision of the power performance standards to be carried out more efficiently in terms of time and cost and to provide a more logical division of the wind measurement requirements into a series of separate standards which could be referred to by other use case standards in the IEC 61400 series and subsequently maintained and developed by appropriate experts. Furthermore, as there are many similarities between the content of the IEC 61400-12-1 ED2 and 61400-12-2 ED1 standards, those methods which could be used by both standards (or future, new power performance method standards) were separated out into new standalone documents in the 61400-12 series. This relates specifically to the site calibration and obstacle assessment methods.
The mandate from TC 88 was that this re-structure should be achieved without introducing any technical changes compared to the current versions of 61400-12-1 and 61400-12-2.

See attachment for further details.

ACTION
IEC national committees are invited to comment on the following:
1. Whether you agree with the split of IEC 61400 12-1 and IEC 61400-12-2 into the new documents with the proposed scope and structure?
2. Whether you agree with the MT to initiate the revision with RR and submit these 9 documents directly as CDV for voting as no technical changes has been introduced?
