After clicking in your link and then chosing LPCXpresso804 from "Example Projects" I am getting redirected to SDK builder and as I mentioned before IEC60730 example projects are no longer available there. I even downloaded the new SDK once again, and IEC60730 were not in the example projects.
Just to make sure you follow what I'm saying is, back in the days I could attach IEC60730 examples by checking it's box in SDK builder, but that library simply does not appear there anymore - please see the attached screenshot

Am I missing something? If so, could you please guide me step by step how exactly I can download IEC example projects?
