Re: [PSES] "For indoor use only" on External Power Supply

It's not helpful to quote a dictionary or grammar when the terminology is not agreed. For Rich, misuse is defined differently from your definition. Game over. This topic is a 'thicket' - something that gets more difficult to penetrate the further you go in. One aspect not commonly studied by

Re: [PSES] "For indoor use only" on External Power Supply

The concept of 'forseeable misuse' as part of RA at least appears, to a reasonable engineer, to be logical construct for evaluating safeguards. But there is no veracity for a mathematical model that would enable the assignment of a "probability" figure that represents a product's safety integrit

Re: [PSES] "For indoor use only" on External Power Supply

I must admit I didn't understand any of that, other than references to MTBF and HALT. It just seems to me that RA is akin to FMEA and FTA (Fault Tree Analysis) efforts, namely, it's just guess work. There is no way to come up with a number that can relied on, since there are too many unknowns

Re: [PSES] "For indoor use only" on External Power Supply

The Machinery Directive requires consideration of possible misuse as part of the risk assessment. Depending on the product I could easily see using an indoor only rated power supply outdoors as possible misuse. In that case depending on the risk/hazard it could mean using an outdoor rated powe

[PSES] Desktop Power Supplies

Dear group, a quick question regarding selling desktop power supplies into the USA as part of a system. If I buy an off the shelf desktop PSU to power my product (unintentional radiator) to sell into the USA does the desktop PSU need to be marked with the FCC logo or verification wording? As par
