## DATE: February 28, 1995 TO: AHAM (Dishwasher Standards Group) FROM: ' Carl E.Adams, Appliance Standards Division SUBJECT: Preliminary Dishwasher Engineering Analysis The Department was notified per your December 2, 1994, letter that the Association of Home Appliance Manufacturers (AHAM), with its members, will be conducting negotiations with non-industry groups regarding a joint comment to DOE pertaining to the next round of dishwasher standards (Docket No. EE-RM-94- 403). On January 24, 1995, AHAM provided the Lawrence Berkeley Laboratory (LBL) with industry data so that LBL could initiate the engineering analyses. LBL has conducted preliminary engineering analyses which are based on the AHAM submitted data except for the motor.design options. Inreviewing the analyses, the Department does have some questions regarding the analyses and data. However, to meet the proposed meeting schedule, the Department is forwarding the preliminary analyses, which are attached for your distribution to all negotiating parties fordiscussion and comment, and will be working to resolve questions. Additionally, the Department is aware that AHAM plans to submit new data regarding adaptive controls. Ifthe additional data is received and/or the Department's.questions result innew or revised data, then the Department would provide an update to the attached analyses prior to your planned March 21, 1995, negotiation meeting. Please direct any questions regarding this material to Marc LaFrance of my staff at (202) 586-8423.
