1、FOR INTERNAL UL OR CSDS USE ONLY NOT FOR OUTSIDE DISTRIBUTION Subject 1017 October 24, 2007 SUMMARY OF TOPICS The following is being proposed for preliminary review and comment only: 1. For Preliminary Review Only: Addition of requirements for portable rechargeable battery-powered appliances. 2. For
2、 Preliminary Review Only: Clarifi cation for polymeric fl uid-handling component requirements. 3. For Preliminary Review Only: Clarifi cation of the meter circuit in Figure 6 Leakage Current Measurement Circuits. 4. For Preliminary Review Only: Addition of installation instruction for a permanently
3、connected appliance. 5. For Preliminary Review Only: Addition of requirements for detachable power supply cords. 6. For Preliminary Review Only: Addition of requirement for coatings applied to the exterior surfaces of polymeric materials and other external polymeric parts. 7. For Preliminary Review
4、Only: Addition of an exception to Clause 4.13.5 for spacings within a motor. COMMENTS DUE: DECEMBER 10, 2007 This proposal is for review and comment only (no ballot at this time). Please note that comments on a preliminary review document will not receive a response from the proposal author through
5、CSDS. Instead, the proposal author will be asked to review the comments and adjust the proposals and/or supporting rationale as the author determines to be appropriate. The preliminary review process is an informal mechanism that provides authors with the opportunity to refi ne their proposals befor
6、e they advance to the next stage in ULs standards development process. In some cases, the author of the proposals may choose to discontinue them. In this case, the author need not do anything after preliminary review has ended. Normally, the next step in the process is the more formal STP ballot and
7、 stakeholder review process. Only comments posted during the STP ballot and stakeholder review process will be provided with a response in CSDS. For your convenience in review, proposed additions to existing requirements are shown underlined and proposed deletions are shown lined-out. Copyright Unde

9、inary Review Only: Addition of requirements for portable rechargeable battery-powered appliances. RATIONALE Proposal submitted by: Rick Slupinski, Underwriters Laboratories UL 1017 presently does not include specifi c requirements for portable rechargeable battery-powered appliances. The following p
10、roposed requirements are, however, based in large part on current practice that is the result of over 20 years experience with such appliances. It is recognized that this proposal does not cover all current or contemplated battery and charging technologies and is not intended to preclude such techno
11、logies. STP discussion resulting from this proposal is anticipated to result in additional proposals that address these other technologies (e.g. Li ion). Reference to UL 2054 in the proposal is intended to drive change in that standard, as appropriate to accommodate the UL 1017 and complementary app
12、liance applications. Crossover applications of battery packs (e.g. in vacuum cleaners, hand tools, lanterns) can inadvertently result in uncoordinated and potentially inconsistent requirements. UL 2054 can provide a common platform for requirements that should be the same, regardless of application,
13、 while permitting differentiation where specifi c applications warrant. The STP is encouraged, via this proposal, to closely examine UL 2054 and offer recommendations, as appropriate, to maximize compatibility of UL 2054 and the UL 1017 application. PROPOSALS 3 General 3.4 Reference publications 3.4
14、.1 Where reference is made to CSA or UL Standards, such reference shall be considered to refer to the latest edition and all amendments published to that edition up to the time when this Standard was approved.
