Reference

Endpoint:

viscosity

Type of information:

experimental study

Adequacy of study:

key study

Study period:

December 2009

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

study well documented, meets generally accepted scientific principles, acceptable for assessment

Qualifier:

according to guideline

Guideline:

ASTM D-445 (Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (and Calculation of Dynamic Viscosity)

Principles of method if other than guideline:

This method covers the determination of the kinematic viscosity of liquid petroleum products, both transparent and opaque, by measuring the time of flow of a fixed volume of liquid at a given temperature through calibrated glass capillary instruments, using "gravity-flow." A procedure is given for a calculation of dynamic viscosities from measured kinematic viscosities

GLP compliance:

no

Type of method:

flow cup (static)

Temp.:

40°C

Parameter:

kinematic viscosity (in mm²/s)

Value:

>= 5.9 - <= 8.8

Remarks on result:

other: Typical value : 6.6

Conclusions:

The viscosity of the substance at 100°F (38.8ºC) varies between 5.9 and 8.8 with a typical value of 6.6

Description of key information

The viscosity has been determined in-company using the test method ASTM D-445

Key value for chemical safety assessment

Viscosity:

6.6 mm²/s (static)

at the temperature of:

40 °C

Additional information

The range of the viscosity of the substance at 38.8ºC varies between 5.9 and 8.8 with a typical value of 6.6, in mm²/s

Based on that the viscosity value, measured at 40ºC, is lower than 20,5 mm²/s for a hydrocarbon substance, the substance is classified for aspiration hazard (Asp. Tox. 1, H 304) according to CLP Regulation.
