I've looked for ISO 10218, 12100, 13849, and IEC 60204, and they're $29.76 to $36.23; $138 for the set. That's a lot better than $183, $207, $230, and $575 that the original publishers want, almost $1200 for the set. The former is likely in the discretionary shop tools budget for most clients, especially if you spread it out over four pay periods, but $1200 would trigger lots of restrictions. But you're right, it's still not free. These are documents that should be on the laptops of every shift lead, maintenance tech, mechanical designer, manufacturing engineer, robot programmer, and controls programmer at industrial plants worldwide. These documents being free would not just make websites easier to use, they'd make human beings safer and reduce the number of industrial accidents that occur. And yet in the hundreds of facilities I've been in and hundreds of customers and vendors I've worked with, I can count on one hand the number of people who had a copy of even one of these documents. The vast majority, in practice, makes do with the regurgitated Powerpoints from various "safety training" presentations that have screenshots of a few tables and critical language. There's an enormous river of prosperity flowing through society. Everyone involved just wants to dip out or siphon off a little bit, what they imagine to be their fair share, or what they think they can convince people ought to be their fair share, and unfortunately, that includes people like the standards bodies. If they published their standards more freely, the total volume of that river would grow enormously, but they would get less of it, so they selfishly don't do that.
