kinematic viscosity (in mm²/s)

The kinematic viscosity of the test substance is recorded to be 1.46 cSt.

Executive summary:

In a publication from Bennett et al., the kinematic viscosity of the substance is recorded to be 1.46 cSt (or mm2/s).

Description of key information

Triethylphosphat is reported to have a kinematic viscosity of 1,46 cSt (or mm2/s), assumed to be at ambient temperature. (publication)

Key value for chemical safety assessment

1.46 mm²/s (static)

Additional information

The kinematic viscosity of the substance is reported to be 1.46 cSt (Bennett et al, 1984). The publication is considered to be a reliable source, therefore it is regarded as a key study.

The substance is not a hydrocarbon, thus there is no concern from low viscosity for Aspiration hazard.
