Tony: Very good response !!! The only thing that I would like to add is that older standards like UL478 were in large based on NFPA70 (The National Electrical Code). Now days the trend seems to be that Agencies like UL are trying a marketing approach called one stop certification, where by doing your work with them they can obtain all the other certifications you need. Therefor they have harmonized their standards with IEC950. There are various ways to do this like the CB scheme, ULc and the older way of MOU. If you only have to deal with one person at one agency to get marks for all over the world it's very convenient. UL has just purchased DEMKO to enhance this ability even more. You will still find that in cases where the National Electrical Code is more stringent that UL will stick to the NEC requirements. This is the case with almost any country in the world. They all have their national deviations but use IEC950 as their standard. This is why when you request a CB Scheme report it is usually done with a specific country in mind. If its just done to IEC950 alone any country where you present this document as proof of compliance will want to assure you meet their deviations.

It is up to local inspection authorities within the US to decide what is required for electrical inatallations. Most use the National Electrical Code in combination with local codes. The National Electrical Code (NEC) does not specifically state that UL Listing is required. Rather, it recommends in a number of areas that materials and equipment be "Listed," " Labelled," or "Identified" by an organization acceptable to the authority having jurisdiction over the equipment installation. UL has done a good job of marketing their service and establishing trust and brand recognition among local inspection authorities. Thus, when local inspectors see the word Listed, they automatically think of UL much like when one says "soda," most people think of "Coke." And they have also done a good job in getting the words "Listed" and "Labelled" used throughout the NEC. Thus, you are able to use any Listing or Labelling service that local inspection authorities require (if any) and will accept. Odds are, if you are selling throughout the USA, UL's "brand" is the most likely to be recognized by local authorities. Companies such as ETL have been fighting an uphill battle on this issue for years and have made significant progress for certain product categories. This is as much a marketing issue as it is a legal one.

For me, it is very clear and very easy. For example, for a = simple Personal Computer, you have to comply with the LV Directive & EMC = Directive. To do that, you can use the corresponding harmonised = standards using any laboratory you wish and give you enough reliance, = including your own laboratory if you have it and offer you enough = facilities. Then, you build the Technical File, sing the Declaration of = Conformity and put the CE marking. That's all for all the European = countries at the same time. You don't have to pay any Certification Body = if you don't wish it and even you don't need to pay the most expensive = laboratories if you have a cheaper one that gives you enough reliance = (please, do not forget that the responsibility is always of the = manufacturer).=20 However, I don't know how is the situation in USA. I know if you have UL = mark, you can sell in any state, but that means you only can use the UL = associated laboratories and you have to pay the certification fee every = year. Much more expensive than the EU system. Is it that true? Are there = any other cheaper system? Are there any clear and single law like the EU = Directives? Are there any WEB in which I could see the corresponding = law? Thank you very much for your answers. =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D Juan P.
