Hi Ian, The last company I was with used to specify a single manufacturer's fan in the UL report including supply voltage / current / CFM) and then (with UL's agreement) include the words "or any recognised equivalent component".
During the factory inspections, if a fan was being fitted from a different manufacturer we would have to produce the fan specification to show that we met the requirements i.e. the fan was UL recognised, supply voltage was the same, current was equal to or less than specified in the report and the CFM was equal to or greater than specified. Thanks, Chris. -----Original Message----- From: John Woodgate [mailto:j...@jmwa.demon.co.uk] Sent: 13 December 2013 11:23 To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re: [PSES] Cooling fan safety query In message <ed08bb5be2d841e0a1b0ca499f924...@dbxpr07mb206.eurprd07.prod.outlook.com> , dated Fri, 13 Dec 2013, "McBurney, Ian" <ian.mcbur...@allen-heath.com> writes: >I believe the fans are listed for the flammability of the plastic body >but I may be wrong. It would surely be worthwhile to check whether UL have confirmed electrical safety, because if not, the test house is probably justified. So you would need to list all the fans that could be used, or find a less exacting test house. -- OOO - Own Opinions Only. With best wishes.
