Being interested by the subject, I followed closely this thread. Found pertinent comments and also a very impolite one like "This appears to be a case of not reading the standard. Please buy a copy and read it." This last one comes in flagrant contradiction with the other emails and with the professionalism of this forum.
I would raise the question about how a power supply with only basic insulation between input and output is suitable for PCs with male D-subs, or for PC headphones which are not isolated for 1500V rms. It would be interesting to see the opinion of our colleagues working in the PC industry.

Does basic insulation or reinforced insulation apply? Particularly in the case that the PC peripherals and male D-sub connectors (that can come in contact with users) are only basic insulated PS suitable. I found that most power supplies available on the market are only tested at 1500VAC between in/out. Thank you in advance for your help, Peter Horvat CAE Inc.
