On that page, they share a YouTube video from a Google Hangouts session on this topic. That video is about 33 minutes long, worth the view in my opinion, and available [here]. This ISO landing page has a nice chart with the evolution of this standard as well as some information about the standards development process - if you are interested in that kind of thing.
