Best source is SAE standard AIR81B

Some details here

http://www.answers.com/topic/hydraulic-fluid

However the area is now vast with speciality oils being churned out by Shell, Mobil, Exxon etc. Now bearing manufacturers are also are chipping in with their fluids .

See here for some guidelines

http://www.interlubecorporation.com/pdf/HydraulicFluidTechnicalPaper.pdf

http://www.machinerylubrication.com/article_detail.asp?articleid=2351

etc.

The viscosity at 400C (ISO VG in CSt) is already explained in previous post (IS46 has 46CSt at 400C...)
