Today in this video, Steve is here to talk about UL, ANSI and IEC 60950. This standard, 60950, deals with the electrical safety of business and information technology equipment. This includes anything that is powered by the mains (120 volt or higher incoming power from the building main electrical power), or a low voltage supply source or battery comes under this standard…that it is used for those applications. UL 60950 is also very useful for the design of similar equipment that might use data processing for its final purpose. Information technology equipment and business equipment and other similar types of machinery, including media servers and other things like that may be used under this standard. Also you might find that 3d printers, laser etchers, and other equipment in some part can use this standard for conformity, of those electrical hazards.

62368-1 is the risk and hazards based standard that will replace the older standards: IEC/EN/UL/CSA 60065, Audio, Video and Similar Electronic Apparatus, and IEC/EN/UL/CSA 60950–1, Information Technology Equipment.
IEC 60950 may cover your equipment more specifically, and there are a lot of other related standards that come into play as well, for flammability and other related needs.
Why is it important that your equipment comply early on during design to this standard?
For most of you at some point you will need to have a listing or labeling done on your equipment. For all USA locations you must prove suitability of use to comply with the national electric code. Also most large government organizations, national labs and large companies require a listing on such equipment. Additionally to ship your equipment overseas, Canada, Mexico, or Europe you have to comply with electrical standards and prove compliance in order to export to those countries.
UL ANSI IEC 60950 is very important for your design phase and early on in your requirements of your equipment. By understanding the details and requirements of UL 60950, you will be much better able to design your equipment, do the design reviews, and the product safety reviews required to ensure your equipment will be easily listed and/or labeled when it is required.
In the future we are going to have a line-by-line video training series about each of the requirements in UL 60950. This will allow you to fully understand the requirements of the standard and with your team understand how that impacts the design of your equipment to make it safe for electrical use within businesses and other facilities.
UL 60950 is crucial to that design process and must be used early on so that you are sure your product is designed to and will be listed and/or labeled at the end. We can provide our Conformity Discovery Process (copy right 2019) during design to uncover non-conforming design or reveal that the design is fully conforming to allow for speed to market.
