I use Eurorack enclosures a lot and design my own front panels, modules, PCBs and backplanes that fit into them. Finding the right dimensional positions of mounting holes for panels and PCBs has always been a pain. Manufacturers of Eurorack components post snippets of info which I have gathered together over the years. Despite all this accumulated info, I still have problems getting modules to smoothly slide into Eurorack enclosures and mate cleanly with my backplane PCBs. What I need is a definitive document defining all the mechanical distances and tolerances. There is such a document - it is IEC 60297-3-101:2004. I have toyed with the idea of buying it but British Standards wants an outrageous £182 for a pdf copy of its 24 pages.
So I have been trawling the internet trying to find a cheaper alternative. Each country seems to sell the the standard in their own language and also in English. I found I could buy it from Switzerland for about£80 and about £60 from Denmark. Then, by chance, I hit upon Estonia where I was able to buy the pdf for a mere £10 which to me is perfectly reasonable.
I am astounded by the range of prices that standards bodies charge. If governments want products to meet standards then the details of those standards really ought to be free or at least easily affordable. In the meantime I will be going to Estonia for mine.
Cheers
