26、lugs Employed in Power-Supply Cords for Use in Range and Dryer Applications Comment Submitter Steve Campolo Leviton Manufacturing CO. Paragraph I Text Reference Section 52A Zomment or Comment Summary 3n the Padded blade issue, I am in general 3greement with the proposal but have serious joubts about
27、 the brass issue. This proposal joes not address the considerable comments I nade about the 70/30 brass verification -egarding stress corrosion cracking. As far as I mow, the ad-hoc committee has not come to my conclusion as of yet. Furthermore, it was suggested that the copper content can go as low
28、 3s 63%. This is out of the question. Since this ssue has not been concluded, I must vote NO ln this as well. If the issue of the brass can be nalized, with acceptable results, I could change ny vote to a yes. It is a shame that this very 3ood and well intentioned proposal is bogged jown in the old
29、brass issue. UL must come to grips with the inherent danger in testing. Most esting has a danger component to it, as it is Nith Stress Corrosion Cracking testing. We have leen looking for a substitute test for over 4 ears now with none in sight. Could not UL simply have the correct equipment and ler
30、sonnel to conduct these tests? ActionlDisposition Disagree No action required. ULs Ad Hoc Committee for 1659/817 Attachment Plug Blade Composition has met and resolved the issues previously identified concerning the composition of brass blades. As detemined at the meeting, even 70/30 brass is subjec
31、t to stress corrosion cracking and therefore it was agreed to discard stress corrosion cracking as a qualification test for brass blades. It was agreed that UL would use ASTM 478 (Standard Test Methods for Chemical Analysis of Copper Alloys), paragraphs 9 - 15 (electrolytic deposition) as the benchm
32、ark or referee method. For follow-up analysis on a quarterly basis, it was agreed that UL would use a method incorporating acid digestion and subsequent analysis by Atomic Absorption Spectrometry (AAS). A proposal is planned for UL 1659, the Standard for Attachment Plug Blades for Use in Cord Sets a
33、nd Power-Supply Cords, therefore, no brass specification will be necessary for UL 817. 2.

35、quires an individual power jpply cord be marked with its rating for OEM Jse. There should be an exception for cords Sized equal to or greater than the attachment jevice rating. Agree The need for the marked rating is to reduce the risk of an undersized detachable power-supply cord being misused for
36、a particular product due to the fact that a flexible cord ranging in size from 18 AWG to 14 AWG can employ the same fittings. As this is not an issue for a power-supply cord employing flexible cord rated equal to or greater than the attachment plug, the proposal has been revised to include an except
37、ion to the required marked rating accordingly. See I DroDosal. Amendix A Copyright Underwriters Laboratories Inc.
