Viscosity Standards

GENERAL PURPOSE VISCOSITY STANDARDS

Kinematic Viscosity in mm2/s (Centistokes)

Kinematic-Viscosity

HIGH-VISCOSITY STANDARDS

These standards are furnished in a range of viscosities and temperatures which are of particular interest in asphalt viscosity determinations and the determination of the viscosities of polymers.

Calibration standards are also available for Dynamic Shear Rheometer (DSR).

Dynamic Viscosity in mPa·s (Centipoise)

FLASH POINT REFERENCE MATERIALS

A total of six different standards are available for the following ASTM methods: ASTM D 56, ASTM D 92, and ASTM D 93. The data provided for each standard includes the average flash point for the lot and the standard deviation observed from 20 tests in 10 different laboratories. Nominal flash points for the various standards are shown in the accompanying table.
