See 17.4.1.1, paragraph 2:

# All library entities except macros, operator new and operator delete are
# defined within the namespace std or namespaces nested within std.

Also see paragraph 4 of the same section.

By the way, the above is from the final standard, which you can get 
  from www.ansi.org. (That's the American National Standards Institute; I 
  could not figure out what organization handles ISO standards for
  Russia.) Last time I checked it was US $18 for the electronic version
  and US $305 (ouch!) for hardcopy.
