Hi Reg - 60950, in its various forms, is the safety standard for Information Technology Equipment. IEC 60950 = 'root' standard. UL60950 = IEC 60950 + US / Canadian national differences. EN 60950 = IEC 60950 + national deviations of all EU/EFTA countries.
IEC 60529 is a standard for determining the relative environmental protection offered by electrical enclosures. This is not a Taiwanese national standard, although it is accepted in Taiwan, when appropriate. IEC 60529 lays out the verification test methods for assigning an 'IP Code' - IP standing for Ingress Protection, and meaning "the degree of protection against the ingress of solid objects and water". The two have nothing in common, really; however, both can apply to any particular product. For example, if your Information Technology Equipment product is to be used out-of-doors, it should have a minimum IP rating of IPx4, meaning that the enclosure protects the internal electronics from exposure to water splashed against the enclosure from any direction. 60950 Annex T refers to IEC 60529 for guidance on the protection against ingress of water. IEC stands for International Electrotechnical Commission. The International Electrotechnical Commission (IEC) is the leading global organization that prepares and publishes international standards for all electrical, electronic and related technologies. IEC standards are often adopted as national standards. Best regards, Doug Massey Product Safety Engineer Advanced Compliance Solutions Ph.
