Standards for Pressure Reducing Valves for Water

I'd like to know what standards are applicable to Pressure Reducing Valves for water. More specifically for water systems in buildings and other water supply systems.
In Japan there is the JIS B 8410:2004 Pressure reducing valves for water works and in Germany there is the DIN EN 1567:2000 Building valves - Water pressure reducing valves and combination water pressure reducing valves.

Which other ones are there?

Thanks!

The AWWA has 22 standards that apply to various valves used in water supplies: http://www.awwa.org/Bookstore/producttopicsresults.cfm?MetaDataID=126&navIte mNumber=5098
