That looks like an ANSI number (not that IEEE isn't involved..).
 From a few googles, it looks like it defines a set of "standard 
environments" to be used as design or test requirements, rather than a 
"recommended practice".

"This is a guide describing the surge voltage, surge current, and 
temporary overvoltages (TOV) environment in low-voltage [up to 1000 V 
root mean square (rms)] ac power circuits. This scope does not include 
other power disturbances, such as notches, sags, and noise. "

Earlier editions in the series talk about recommended practice, but the 
recommended practice is for "testing" not "installation".

Sort of like UL1149 describes test methods for TVSS, not performance 

For usage, Standler's book:"Protection of Electronic Circuits from 
Overvoltages" is the hot ticket.

It's also on google books, so maybe the pages that are visible that way 
give you useful knowledge.
