Amund, To expand on what Rich as said, UL adapted IEC 60950 ITE products and IEC 61010 commercial/industrial electronic equipment as UL standards early on so there have been harmonized IEC/UL requirements for these products for 30 years; IEC 60950 has been replace by IEC 623268-1 IT& consumer electronic products & as you know. Other IEC standards have been adapted by UL for the US market; IEC 60065 for TVs, IEC 60601 for med devices and IEC 60335 for household appliances - to name some key ones - over the years to aid manufacturers to develop products for the worldwide market. So a large portion of consumer/commercial products are being designed against these harmonized requirements. Others will be adapted as manufacturers press UL to do so.
Remember, tho, that the US does not accept a manufacturer's Declaration of Conformity; only 3rd party certifications are accepted in the US so the mfgr must get a cert mark from a US NRTL to show compliance. :>) br, Pete Peter E Perkins, PE Principal Product Safety & Regulatory Affairs Consultant PO Box 1067 Albany, ORe 97321-0413 503/452-1201 IEEE Life Fellow IEEE PSES 2020 Distinguished Lecturer <mailto:[email protected]> [email protected] Entropy ain't what it used to be From: Richard Nute <[email protected]> Sent: Thursday, January 21, 2021 2:24 PM To: [email protected] Subject: Re: [PSES] UL = IEC ?? Hi Amund: First and foremost, both the IEC and UL make money selling standards. Second, UL does not adopt any IEC standard, or most other non-UL standards. UL will test to an IEC standard, and may issue a CB test report, but not the right to use their certification mark. UL will only issue the right to use their certification mark if the product meets the UL standard. UL writes their own standards. If industry insists, UL will start with an IEC standard and re-write it to meet their requirements (often justified as meeting USA National Electrical Code requirements). To be fair, Americans often add more requirements, too (which are gladly accepted by UL as such additional requirements mean additional testing and additional income). UL is an ANSI-approved standards-writing organization. As such, virtually all UL standards are also ANSI standards. All other certification houses must use UL/ANSI standards for their certification. Best regards, and stay safe!

When IEC publish a standard, do UL adopt it as is, or do they modify it? I guess this will vary form case to case. Right?
