WT CAC Clarification Sheets
The IEC WT Clarification Sheets are recommendations issued by WT CAC to support uniform application of IEC 61400-22 and related standards. The Clarification sheets are issued for use by the participating Certification Bodies and Test Laboratories. Everyone in the wind industry are welcome to request clarifications to the certification scheme by using the CS template. The request will be handled by the appropriate CAC subcommittee in line with the CS procedure.
Interpretation sheets differ from Clarification sheets as Interpretation Sheets are Formal decisions of the Technical Committee responsible for a Standard and are required to be developed and approved within the respective Technical Committee.
