### May 9, 2010 To: Margaret Sheppard, EPA Yaidi Cancel, EPA Subject: Status Interior Climate Control Standards Committee SAE J Standard Documents From: Ward Atkinson, SAE Interior Climate Control Standards Committee Bill Hill, SAE Interior Climate Control Standards Committee

As of this date we have completed most of the documents that cover the use of R-1234yf and interface within J639. As noted some are being sent to MVC members for ballot. J639 has not completed the final ICCSC ballot approval process and when approved will be forwarded to MVC for their approval. When all documents receive final approval by MVC, this will then result in publication and availability of all the documents. The table below indicates the current status of 17 standards, and 11 of the documents have been forwarded to MVC for balloting. Six standards are still in the ICCSC ballot approval process and should be completed within the next few months and will then be forwarded to MVC for balloting.

Please contact us should you have any questions.May 9, 2010
