44、t intended to be a verbatim transcript of the discussion at the meeting, but is intended to record the significant features of those discussions. 1. 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 Lig
45、hting 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 add
46、s 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 dis
47、cussion, 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
48、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
