Standards No. Standard Title & Description Summary of KEY Requirement Changes Effective Date
UL 1363 Relocatable Power Taps, 2nd Edition Relocatable Power Taps (RPTs) intended for use with medical equipment as defined by Article 517 of the National Electrical Code for Health Care Facilities shall comply with the requirements of the Standard for Safety of Medical Electrical Equipment, Part 1: General Requirements, UL 60601-1 and the Standard for Safety Requirements for Medical Electrical Systems, IEC 60601-1-1.
RPTs that incorporate a molded-on or assembled-on hospital grade attachment plug or receptacles shall provide with an additional cautionary marking both on the RPT and in the instructions, packaging, or other literature accompanying the RPT.
UL 1005 Electric Flatirons, 4th Edition Flatirons with water reservoirs are required to be subject to a drop test with the reservoir filled. This will require a retest of all presently Listed flatirons employing reservoirs. 2005/8/18
UL 985 Household Fire Warning System Units, 5th Edition Requirements added for separation of power-limited circuits from non-power-limited System Units, 5th Edition circuits in order to correlate with the requirements of Article 760 of the 2002 National Electrical Code (NEC). While no testing will be necessary, a review of the products and/or installation instructions will be required.
Revised the Audibility Test to specify measurement in a reverberant room, which has been qualified for pure tones under either Precision Methods for the Determination of Sound Power Levels of Broad-Band Noise Sources in Reverberation Rooms, ANSI S12.31, or Precision Methods for the Determination of Sound Power Levels of Discrete-Frequency and Narrow- Band Noise Sources in Reverberation Rooms, ANSI S12.32. This is consistent with the test methods used in UL 1023 and UL 294. The revision will require a review and retest of some alarm sounding devices used in household fire warning system units.
UL 1059 Terminal Blocks, 4th Edition Terminal blocks that had previously been temperature size larger than what would have been selected based on the assigned ampere rating of the terminal block will need to be re-tested with the smaller wire size. Table 11.1 of UL 1059 has been revised to address allowable temperature rises for fuse type terminal blocks. Different temperature rises for bus, straps, fuse clips and connectors are specified, depending upon if the fuse type terminal block is tested with live fuses or dummy fuses. 2005/9/11
