SQL Standards Download...It's useful, but is it legal?

So much as a couple of years ago, I stumbled upon this link:

http://www.ncb.ernet.in/education/modules/dbms/sql99index.html

It pops up at page 14 when googling for "ISO 9075".
I have no means of checking it it's is genuine, but everything suggests it is.

Funny thing is, I always thought that these cost money, even though this version of the standard is outdated.
