Hello Rich, That may be true for equipment used in the work place and for installation in commercial and new constructions where an AHJ will inspect the building but is this really true for consumer products where someone buys an electronic product from the store brings it home and plugs it in??
It may be a liability issue and or a marketing issue, as I believe many big chain stores mandate a UL or other NRTL mark on equipment they sell in their stores, but I am not sure having an NRTL mark on a consumer product is a "quasimandatory" as you mention other then where required by State law? Look forward to others opinions.......... BTW on a lighter note.......there may be good news for all the wine lovers on the list as the Supreme Court recently ruled that States cannot ban direct sales to consumers from out of state wineries if they allow direct sales from in state wineries.....Not a complete victory but a nice start!! http://www.winebusiness.com/news/DailyNewsArticle.cfm?dataid=37850 Best regards, John From: [email protected] [mailto:[email protected]] On Behalf Of Rich Nute Sent: Tuesday, May 17, 2005 8:22 PM To: David Greig Cc: [email protected] Subject: Re: UL Approval in different States Hi David: > In the past I believed that only 2 States actually required UL > product approval for import. > > Is this correct, and if so in which 2 States is UL mandatory? Except for wine, there is no restriction on trade among and between the states. :-) In the USA, there are two sets of rules that require UL certification of products. The first set of rules is that of the Occupational Safety and Health Administration, OSHA. This is a federal government organization and is a part of the Department of Labor. For the safety of employees, OSHA requires electrical equipment to be certified by a NRTL. UL is a NRTL. The second set of rules is that of the National Electrical Code. This set of rules is adopted by local building code authorities. ("Local" can mean city, county, or state.) For the safety of an electrical installation, all parts of the installation must be certified by UL, CSA, or other organization accepted by the local building code authorities. UL, CSA, and ETL have worked very hard to be accepted by every building code authority in the USA. These two sets of rules are independent of each other. However, UL, CSA, and others are qualified under both sets of rules. For all practical purposes, UL or equivalent is mandatory throughout the USA to satisfy either one rule or the other or both.
