VWR®, Viscosity standards
10 cSt, 8,7 cSt, 6 cSt, 5,7 cSt, 4,4 cSt, 500 mL
These standards can be used for calibration, control, verification, qualification or method validation of kinematic and dynamic viscosity measurement instruments (both manual and automatic). Each standard is certified for kinematic viscosity (mm²/s, cSt), dynamic viscosity (cP) and density (g/ml) at a range of temperatures.
- Manufactured from high quality, stable base oils and additives
- Extended shelf life with secure packaging
- All standards observe Newtonian fluid behaviour
These standards are traceable to the ITS 90 temperature scale and the universally accepted primary standard value of the viscosity of water at 20 °C, defined as 1,0034 mm²/s (cSt) by ISO 3666.
: Certified according to ASTM D2162 using Ubbelohde master viscometers and ISO 17025 accreditation for calibration.
