1) Not sure 2) 150 C Edit: Oops, I just realized the number I posted was for ASTM 5800, not sure if they are done at the same temp. or not. [ November 11, 2002, 04:47 PM: Message edited by: mdv ]

1) High Temperature/High Shear (HTHS) Viscosity @ 150°C (ASTM D 4683) - I have not read this ASTM, is 150°C specified or are there options??? I guess what I'm asking is 150°C standard? 2) Noack Volatility, % weight loss (g/100g) (DIN 51581) - what temperature is this at??? Thanks

No offense taken at all, I knew what you meant. It's just after seeing your post I realized my brain and fingers weren't communicating either
