Subject 1206 September 14, 2012 SUMMARY OF TOPICS The following changes in requirements to the Standard for Electric Commercial Clothes-Washing Equipment, UL 1206, are being proposed: 1. Installation Clearances and Cycle Selection STP BALLOTS AND COMMENTS DUE: October 15, 2012 UL’s goal is to have no interest category comprise more than one-third of the STP membership balance. To improve the current balance for STP 1206, UL is looking for participants in the AHJ, Commercial and Industrial User, Consumer, General, Government, and Supply Chain interest categories. Definitions for these interest categories are available on the Standards STP Internet site: http://www.ul.com/global/eng/pages/solutions/standards/developstandards/participation/ interestcategories/ If you are interested in applying for STP 1206 membership or are aware of potential candidates for this STP, please contact the STP Project Manager, Amy.K.Walker@ul.com. For your convenience in review, proposed additions to existing requirements are shown underlined and proposed deletions are shown lined-out. 1. Installation Clearances and Cycle Selection RATIONALE Proposal submitted by: Michelle Andersen, UL LLC The standard does not currently include specifics for the installation of appliances other than recessed or wall-insert appliances during the Temperature Test. These appliances may be provided with installation instructions defining the required clearances to all adjacent surfaces. Paragraph 36.11.1 and Section 51 have been added to address the installation for the Temperature Test and outline the installation instructions required for these appliances. Additionally, the standard does not currently indicate how to handle dryers with more than one cycle selection or where the cycle parameters can be adjusted. Paragraph 36.12 was revised to include directions for testing with the cycle parameters that result in the highest temperatures. PROPOSAL 36.11.1 An appliance, other than a recessed or wall-insert appliance, shall be placed on a horizontal surface and located within an enclosure formed by three flat-black-painted, vertical surfaces of nominal 9.5 mm thick plywood. The spacings to each enclosure surface shall be as specified by the installation instructions. If no spacings are specified in the installation instructions, the enclosure surfaces shall be SUBJECT 1206 -2- SEPTEMBER 14, 2012 located as close to the back and both sides of the appliance as possible. The sides shall extend not less than 610 mm beyond the physical limits of the front and the top of the appliance. Temperatures are to be measured at points on the inside surface of the test enclosure. 36.12 An appliance intended to be operated in cycles is to be operated for successive operations of the machine through the complete cycle dictated by the control. If the appliance has more than one cycle selection or the cycle parameters may be adjusted, the complete program cycle(s) that results in the highest temperature rises shall be used. A 4-min interval is to be allowed between successive cycles to permit rearrangement of the clothes load. Hot water is to be supplied to the appliance at a temperature of 82°C (180°F), and both hot and cold water are to be supplied to the appliance at a pressure of 40 – 60 psi (276 – 414 kPa). If the appliance is intended to be drained to an opening above floor level, the outlet of the hose from the drain pump is to be 36 in (914 mm) above the floor on which the appliance rests. With the concurrence of those concerned, laundry detergent in accordance with the operating instructions may be added to the appliance at the beginning of each cycle. 51 Installation Instructions 51.1 An appliance other than a recessed or wall-insert appliance shall be provided with installation instructions that specify the required clearances to all adjacent surfaces. Exception: The installation instructions need not specify clearances to all adjacent surfaces if the appliance complies with the Temperature Test of 36 with the appliance installed so that the enclosure surfaces are located as close to the back and both sides of the appliance as possible.
