The result from either standard is a compliant product, not necessarily a safe product. Certainly unlikely to be a safety problem if compliant with an applicable standard.
I'd like to see a generalized approach to product safety with one or two generic standards and not the large proliferation of standards which we have today. _______________________________________ _____________________________________________ Ralph McDiarmid | Schneider Electric | Renewable Energies Business | CANADA | Regulatory Engineer From: Richard Nute <[email protected]> To: [email protected] List-Post: [email protected] Date: 09/15/2010 04:01 PM Subject: Re: [PSES] SV: [PSES] IEC 60950-1 vs IEC 60601-1 ________________________________ > But we would also assume that a 601-1 PSU should be more "safe" than an > 950-1 PSU, seen from an application point of view. We cannot deem safety to one standard as being "more safe" than to another standard. We can say that the standards are different. The result of both standards is a safe product. The standards are for different use domains. Such usage differences may be cause for different limits. requirements, and tests. And, as one of my HP colleagues said, "Safety standards are the collective inversion of bad experiences." The medical standard is based on bad experiences in medical situations. Same for the IT standard. So, they are different, but both provide a safe product.
