Re: [PSES] IEC 60950-1 PSU acceptance

Ian, I believe you to be correct.   What you may want to do is to ‎specify "conditions of use" for your 60065 product to limit it's use to the limitations of the 60950 PSU. This would include all environmental conditions such as temperature, humidity, pollution degree, altitude and the electrical conditions such as overvoltage category voltage range and overcurrent protection. This would be included in the certification file as well as in the user documentation.  All the best, Doug Douglas E Powell doug...@gmail.com ‎https://www.linkedin.com/in/dougp01   ‎ From: McBurney, Ian Sent: Tuesday, January 5, 2016 6:00 AM To: EMC-PSTC@LISTSERV.IEEE.ORG Reply To: McBurney, Ian Subject: [PSES] IEC 60950-1 PSU acceptance Dear Colleagues.   A happy new year to you all!   I have a problem with a well-known safety testing agency regarding an AC/DC “wall wart” type adapter. The adapter is fully approved to IEC/UL 60950-1 but in this case I am using it to power a product that is being evaluated to IEC/UL 60065.   The agency has informed me that the adapter has failed approval due to the softening temperature of the insulating material supporting parts of the adapter as specified in clause 7.2 of IEC 60065.   I thought there was an agreement that if a power supply met the requirements of IEC/UL 60950-1 it would be acceptable for use with products tested to IEC/UL 60065 provided it was used within its performance specification.   Is this belief incorrect?   Many thanks in advance.   Ian McBurney Design & Compliance Engineer.   Allen & Heath Ltd.
