The viscosity values for certified viscosity check oils have been tested and certified at typical blend targets. These check oils are for validating the performance of cold cranking simulator and kinematic viscometers by measuring commercially available formulated engine oils.

• Kinematic viscosity mm²/s (cSt) in accordance with ASTM D445
• Fully traceable to national standards
• Tamper-evident security packaging

Kinematic viscosity measurements have been made in accordance with ASTM D445, using reference viscometers certified in accordance with ASTM D446 and ASTM D2162.

Values for density (ASTM D4052), CCS Dynamic Viscosity mPa.s (cP) in accordance with ASTM D5293 and Viscosity Index in accordance with ASTM D2270 are provided in the documentation.
