Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Key value for chemical safety assessment

Additional information

Other lubricant base oil viscosity is considered to be > 2 mm2/s at 40°C. A viscosity range of 1.99 to 847 mm2/s at 40°C was reported by CONCAWE (2010a). The viscosity was determined using the EN ISO 3104/ ASTM D 445 test method.

Other lubricant base oil viscosities may also be characterised by measured values for several lubricant base oil samples, which range from 4.48 to 1300 mm²/s at 40°C, (viscosity values for the same samples at 100°C were 3.08 to 50 mm²/s), according to Method ASTM D 445 (CONCAWE, 1984; 1997). These studies received Klimisch scores of 2 and are classified as reliable with restrictions.
