It’s not the same product category and unlikely to cause confusion. Those are two of the major considerations in trademark law at least in the US. On the other hand, the rights holder has to vigorously defend the mark or lose it. That often leads to a bit of overreach rather than the opposite.

I don’t see any claim of trademark on the CSCS website about their framework. You can’t infringe what’s not claimed.

Copyright typically doesn’t cover names of things. That’s what trademarks or service marks are for.
