content: Hi,Is there anywhere, in any EU country including UK, (or Aus, NZ and USA , Canada etc) where one can go, and pay a little fee, and then have access to read all or any of the (latest publication) EN standards for Electrical and Safety regulations?eg....· EN 61000-6-3· EN 61000-6-1· EN 55032· EN 55014-1· EN 55014-2· EN 61000-3-2· EN 61000-3-3· EN 55024· 47 CFR Part 15· GB 17625.1· GB 4943.1· GB/T 9254· K 60950-1· KN32· KN35· EN 55035..or is there a VPN that you can have access on, and pay for say an hour of access to all standards?

content: My Uk public library (Essex) had free online access to BSI standards via the county library website - not sure if they still do though.Apparently Estonia is a good place to get cheap copies of standardshttps://openregulatory.com/accessing-standards/

content: Thanks, on this page...https://www.evs.ee/en/evs-en-iec-62368-1-2020-a11-2020-consolidated..it says you can pay Euro 2.40 and have 24 hours of access to EN62368-1.Thing is, you have to give your bank details...and would you trust them not to take a load more dosh out?The author of the site you kindly posted is fairly derogatory about the respectible-ness of the Standards bodies.It does seem very odd, as he says, that Safety standards, are not free.He makes reference to the "standardisation mafia".

content: Quote from: Faringdon on April 30, 2023, 03:08:50 pmI have purchased standards from evs.ee without any problems. Tho I woudn’t be suprised if you would manage to lose your parents house in the process.

content: Quote from: Faringdon on April 30, 2023, 07:01:37 pmUmm, they offer paypal and major credit cards as payment method and you don’t even need to register.Bank details are needed only if you have Estonian internet banking system and you want to use that.

content: FTTS, Beware that such standards are subject to copyright law worldwide.The origial agency prices reflect the cost to research, maintain and promilgate a standard.As an ex member of the AES standards commitee the work is often long, difficult and unpaid.The alternative sources mentioned may be considered illegal copyright infringement.The alternative sources mentioned may have changed, fake or obselete information.It would be wiser to your base safety and compliance designs or tests on the genuine original standards and regulations.If they exist, your "customers" should easily cover the cost to acquire the required standards.In our SMPS/compliance/EBU consulting and design 1970s..1990s indeed we purchased many UL/IEC and FCC/FAA printed standards.The cost was included in our invoices to the variois customers.Finally a good engineering school library may have most standards in print or computer acess format.AmicalmentJon

content: Actually the AES are pretty reasonable, they have an online library that costs about a hundred quid a year, and gets you free access to their entire back catalogue of papers, journals and standards, TOTALLY worth it if audio doings are your thing, or you can buy individual standards and papers for IIRC $20/ea.The IEEE are an expensive pain as are BSI.The cheeky ones are SMPTE who when writing their 'own' standards take a mix of AES, IETF and (sometimes) IEEE standards by reference, add some minor tweaks and then publish for an arm and a leg and play copyright games. Yea, ST-2110, looking at YOU.What they all tend to do which is annoying is to include other standards by reference, you almost always find you need a half dozen of the things to get what you need.

content: F4eru: Answers to your rude and baroque note..."So they make BOATLOADS of money, have you as a slave write for absolutely free, and you still defend those obsolete copyrights"1/ The AES looses money n standards, like most professional organizations, it is a non-profit and most income is mmebership fees and trade shows.2/ The STD comitee members are all volinteers who offer their time and council in specialized areas to advance the industry.3/ Similar for IEC, IEEE, NEC and other standards that exist.4/ As an author and inventor, I had written and procecuted patents that are liscenced and in use, and written IEEE Spectrum articles.Copyright is essential and thieft of IP is bad for everyone, the authors and the users, just as is thieft of money or objects.CordialmentJon

content: dmills the various standards you mention for safety and EMI, are harmonized such that the USA /EU/CA, UK for may are essentially interoperable and the same.Differences exist for local situations eg type of power mains config, mains voltage, frequency etc.Similar re AES/EBU/IEC for digital audio.Jon

content: Quote from: f4eru on May 03, 2023, 03:42:34 pmWhen you design electronics products, you should be able to dish out that small amount for the standard. It's the price of being in this business. The engineer reading the standard is getting payed more for that time than the cost of the standard.
