UL Standard for Safety for Electric Baseboard Heating Equipment, UL 1042
Fourth Edition, Dated April 11, 1994
Revisions: This Standard contains revisions through and including February 11, 2008.
Summary of Topics
Revision pages have been issued for the Standard for Electric Baseboard Heating Equipment,
UL 1042, to reflect the latest ANSI approval date and to incorporate the proposals dated
September 21, 2007 and November 23, 2007. These proposals include the following:
• Additional supply cord requirements added to Section 11, Section 55, and new Sections
52A – 52E and 54A.
• Revision to Paragraph 33.2.1 to clarify the requirements for normal operation and
temperature-limiting devices.
• Revision to Paragraph 13.3.1 to include additional manufacturing and production line
tests under the QA audit program.
UL Standards for Safety are developed and maintained in the Standard Generalized Markup Language
(SGML). SGML -- an international standard (ISO 8879-1986) -- is a descriptive markup language that
describes a document’s structure and purpose, rather than its physical appearance on a page. Due to
formatting differences resulting from the use of UL’s new electronic publishing system, please note that
additional pages (on which no requirements have been changed) may be included in revision pages due
to relocation of existing text and reformatting of the Standard.
Text that has been changed in any manner is marked with a vertical line in the margin. Changes in
requirements are marked with a vertical line in the margin and are followed by an effective date note
indicating the date of publication or the date on which the changed requirement becomes effective.
The following table lists the future effective dates with the corresponding reference
