[PSES] UK plug
Hi Im trying to find the right standard for a wall-plug PSU with integrated BS 1363 plug. I have bought the BS 1363-1, -3 and -5 standards, very expensive :-( but they all exclude plugs with integrated components, or am I wrong? What is the right standard to use?

Re: [PSES] UK plug
Hi Kim, What will be the PSU used for? Standard depends on the application. If the PSU will be used to supply information technology equipment then standard EN 60950-1 is applicable. BS 1363 is used just to verify plug part. I hope it helps.

[PSES] RF test cables
I've always found Semflex to be a good choice for the money. I believe they have changed names but they should be still searchable. The last cable I bought was their HP305. Good to 18 GHz. I wanted the lowest loss with the widest bandwidth. I have no financial interest in the company.

Re: [PSES] Audio Frequency Induction Loop
John EN50121-2:2006 states in Table C1 that the typical magnetic field from a 750V catenary railway drawing 1000A at 10m is 15 micro Teslas (15000nT or 15 µT). The field will decay at approximately the distance squared ; so at 35m the field will be down to around 10nT. BS EN 60118-4:2006. This standard states : 5.2 Environmental audio-frequency magnetic background fields The function of the installed induction loop system may not be satisfactory if there are undue environmental magnetic background fields. The maximum A-weighted environmental magnetic background noise level re 1 A/m, measured with the time weighting S (as defined in IEC 61672), should not exceed – 40 dB anywhere in the operational area. I am conducting some tests on the tram tonight which should give me some more figures to use.

From my very basic calculation you need a significant separation distance (in excess of 25m). Any previous studies or examples would be most helpful. I don't have any studies or examples, but I'm heavily involved with that standard; I'm actually editing the next edition today! Of course, the system doesn't pass DC and very low and high frequencies, so it's a question of transients, from about 20 ms down to perhaps 100 μs. If you care to tell me how you calculated 25 m, I will compare it with my calculations. Meanwhile, I'll ask around in the AFILS community. Any reports submitted here might well contribute to the next but one edition of IEC 60118-4 or a planned Technical Report covering all aspects of AFILS - purchase, design, installation, maintenance and 'care and feeding'. -- OOO - Own Opinions Only.

[PSES] 3rd Edition of CSA Z432 - Safeguarding of Machinery
Friends and colleagues, Tomorrow marks the start of work on the Third Edition of CSA Z432, Safeguarding of Machinery. This standard has not been revised since the 2004, when the second edition was published, and there are many advances technologically and philosophically that have occurred since then. I sit on this committee, and as a member of the PSES, I want to be able to represent your concerns to the committee. If you have questions concerns or ideas that you would like the committee to consider as we work on the third edition, I welcome your input. I cannot guarantee that all suggestions will be included in the document, but I am more than happy to bring your concerns to the committee for consideration. I will update this community on our progress as much as I can. I look forward to hearing from you!

[PSES] SV: [PSES] UK plug
Hi Bostjan Sorry for not being so specific. I know that the PSU shall comply with EN 60950-1, it's a USB PSU. But it comes in different versions with amongst other with the UK plug. I found a British web page that informed that over 1000 different plugs have been found over the last couple of years that did not comply with the BS 1363. So my concern is to find the right parts of BS 1363 or a separate standard that addresses the plug of a wall-plug type equipment.
