The testing standards were revised over a period of time from 2014-2015 and were fully implemented in bike design for those model years and right after. This was done to catch up to disc brakes - especially hydraulic - thru-axles, and a larger portion of drop-bar bikes designed to be ridden off-road. They apply to bikes based on their design intent, which is different for road/city/mtb.
The ISO/EN standards are not free or openly available, they cost 118CHF and are generally not something a hobbyist buys. People who work with them generally are not posting on forums (because it's a waste of time).
This isn't something I randomly started googling today to argue about it. I've been paying attention to this and researching for a while - ever since I found my production randonneuring bike had an almost 3 pound fork for some reason while the 2012 disc cross bike had a way nicer feeling fork that was more than a pound lighter.
