Subject or Topic: Clarification of flammability requirements for lighting strings that employ non-replaceable lamps Comment Submitter S. Altamura Paragraph I Text Reference 22.2.1 . I Comment or Comment Summary ActionlDisposition I I am not sure that the revision to 22.2.1.1 of the subject UL 588 bulletin does what you want. I read it now that both push-in and non- replaceable constructions are exempt as the midget and miniature sizes do not encompass the push-in lampholder or non-replaceable. Can you please clarify how this deletion of “push-in“ requires both the push-in and non- replaceable lampholders to comply with the requirements to be molded from QMT02 plastic (¡.e 1694 type material with a 300 mm distance to the cotton)? UL intends to modify the proposal as discussed at the STP 588 meeting held on September 15 and 16, 2003 and outlined in UL Subject 588 Bulletin, dated October 29, 2003, to clarify the intent of the requirement. -,-,- SUBJECT 588 -BI- NOVEMBER 13,2003 APPENDIX B PROPOSED REQUIREMENTS FOR THE EIGHTEENTH EDITION OF THE STANDARD FOR SEASONAL AND HOLIDAY DECORATIVE PRODUCTS, UL 588, AS REFERENCED IN COMMENT MATRIX CHART.

CLARIFICATION OF FLAMMABILITY REQUIREMENTS FOR LIGHTING STRINGS THAT EMPLOY NON-REPLACEABLE LAMPS PROPOSAL 22.2.1.1.1 The body of a Istt4k-tft lampholder which is less than 0.15 inch3 (2500 mm3) shall be molded of a material that has a flammability rating of SC-O or SC-1 in accordance with the Standard for Tests for Flammability of Small Polymeric Component Materials, UL 1694 when testing is performed on standardized flame bars of 55 (10.5) x 13.0 (10.5) mm at a thickness of 0.8 (IO.l) mm or less. In addition, the lampholder must comply with the Flammability Test for Small Components specified in UL 1694, except that the bottom of the lampholder shall be located 11.8 10.39 inch (300 I10 mm) above the cotton indicator and the flame application time shall be 10 seconds. Total consumption of the component or specimen or ignition of the cotton indicator by flaming particles or drops shall not be allowed. 22.2.1.4 i-ÛÏ a p- , Thespacing between parts of opposite polarity and between live lamoholder The push-in lamp shall be provided with an adapter which secures the lamp into the lampholder by push-in friction fit, or by a latching mechanism which snap-fits the lamp in place. The adapter shall be constructed of the same material as the lampholder. and dead metal parts shall not be less than 1/32 inch (0.8 mm) for a DUS h-in or non-redaceab ie 22.2.1.6 #we+wti x i be e x - -parts in a series-connected Istt4k-n; ÛÏ mtdgekw lampholder shall not be exDosed before, during, or after insertion of a lamp of the size for which the lampholder is intended. Accessibility of live parts is to be determined by contact with the probe illustrated in Figure 9.1. The probe is to be inserted into any opening in the lampholder or lamp, or the lampholder and lamp assembly. . . Exception: A lampholder located in a Class 2 circuit need not comply with this requirement. -,-,- Subjects 588 (2388) (in reply, refer to Subject 588) 1285 Walt Whitman Road Melville, L.I., NY 11747 October 29, 2003 TO: Standards Technical Panel (STP) for Seasonal and Holiday Decorative Products, Subscribers to ULs Standards Services for STP 588 Seasonal and Holiday Decorative Products, UL 588 Flexible Lighting Products, UL 2388 Other Interested Parties SUBJECT: Report of the Meeting of the Standards Technical Panel of UL for Seasonal and Holiday Decorative Products, STP 588; PROPOSED EFFECTIVE DATES The following topics were discussed at the meeting: SUMMARY OF TOPICS UL 2388 I ) Revision of scope of UL 2388 2) Revision of flammability rating in paragraph 7.2 (STP member proposal) 3) Revision of temperature rating of polymeric materials in paragraph 7.9 (STP member proposal) 4) Clarification of A WG requirements for stranded conductors 5) Addition of fusing requirements to Table 14.1 6) Revision to clarify requirements in paragraph 23.

REVISION OF SCOPE OF UL 2388 DISCUSSION A STP member submitted a proposal to differentiate between the scopes of UL 2388, the Standard for Flexible Lighting Products, and UL 588, the Standard for Seasonal and Holiday Decorative Products in order to clarify and reduce the risk of confusion of the products covered under each standard. A STP member indicated that the clarification is not readily apparent as the proposed revision to the scope only adds the term “temporary-use“. The member also stated that if the scope of UL 2388 is revised to clarify that UL 588 products are not covered under the standard, then a similar revision should be proposed to UL 588 to indicate that UL 2388 products are not covered under that standard. After a short discussion, the STP decided to maintain the revision to the scope of UL 2388 as proposed, and in addition in an effort to maintain consistency, propose a revision to the scope of UL 588 that the standard does not cover flexible lighting products. Proposals relating to this item are located in Appendix A, item 1 and Appendix B, item 35. 2. REVISION OF FLAMMABILITY RATING IN PARAGRAPH 7.2 (STP MEMBER PROPOSAL) DISCUSSION There was a discussion of a proposal initiated by a STP member that would revise the minimum flammability rating of the polymeric material used to enclose or provide structural support to the flexible lighting product from V-I to V-O and the HAI (high-current arc resistance to ignition) PLC from 2 to 3. The STP member who submitted the proposal indicated that flexible lighting products covered under UL 2388 are permanent and not intended for temporary-use therefore
