ASTM D341 Standard Practice for Viscosity-Temperature Charts
ASTM D341 Standard Practice for Viscosity-Temperature Charts for Liquid Petroleum Products
4. Description
4.1 The charts are designed to permit kinematic viscosity-temperature data for a petroleum oil or fraction, and hydrocarbons in general, to plot as a straight line over a wide range. Seven charts are available as follows:
Chart I - Kinematic Viscosity, High Range:
Kinematic Viscosity: 0.3 to 20 000 000 cSt
Temperature: -70 to +370°C
Size: 680 by 820 mm (26.75 by 32.25 in.)
Pad of 50
ADJD034101

Chart II - Kinematic Viscosity, Low Range:
Kinematic Viscosity: 0.18 to 6.5 cSt
Temperature: -70 to +370°C
Size: 520 by 820 mm (20.5 by 32.25 in.)
Pad of 50
ADJD034102

Chart III - Kinematic Viscosity, High Range:
Kinematic Viscosity: 0.3 to 20 000 000 cSt
Temperature: -70 to +370°C
Size: 217 by 280 mm (8.5 by 11.0 in.)
Pad of 50
ADJD034103

Chart IV - Kinematic Viscosity, Low Range:
Kinematic Viscosity: 0.18 to 6.5 cSt
Temperature: -70 to +370°C
Size: 217 by 280 mm (8.5 to 11.0 in.)
Pad of 50
ADJD034104

Chart V - Kinematic Viscosity, High Range:
Kinematic Viscosity: 0.3 to 20 000 000 cSt
Temperature: -100 to +700°F
Size: 680 by 820 mm (26.75 by 32.25 in.)
Pad of 50
ADJD034105

Chart VI - Kinematic Viscosity, Low Range:
Kinematic Viscosity: 0.18 to 3.0 cSt
Temperature: -100 to +700°F
Size: 520 by 820 mm (20.5 by 32.25 in.)
Pad of 50
ADJD034106

Chart VII - Kinematic Viscosity, Middle Range:
Kinematic Viscosity: 3 to 200 000 cSt
Temperature: -40 to +150°C
Size: 217 by 280 mm (8.5 by 11.0 in.)
Pad of 50
ADJD034107

4.2 Charts I, II, V, and VI are preferred when convenience and accuracy of plotting are desired. Chart VII is the middle range section of Chart I at somewhat reduced scale. It is provided for convenience in connection with reports and data evaluation. Charts III and IV are the same as Charts I and II and are provided in greatly reduced scale for convenience in connection with reports or quick evaluation of data. These latter charts are not recommended for use where the most accurate interpolations or extrapolations are desired.
