An error has been identified in the 2010 published version of IEEE Standard C57.12.31. During the C57 Enclosure Integrity Working Group's last review of the standard some copy/paste modifications were made from the C57.12.28 to the C57.12.31 standard. In section 4.5.6 Simulated corrosive atmospheric breakdown (SCAB) test the number of cycles was changed from 10 to 15. The number of cycles in the C57.12.31 standard should be 10 as originally stated in the 2002 publication of the standard. At the October 23, 2012 meeting of the C57 Enclosure Integrity Working Group there was a unanimous vote to correct the number of SCAB cycles to 10 and proceed with an IEEE Corrigenda.
