Endpoint:

viscosity

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: see 'Remark'

Remarks:

Reliability was rated as 2 because viscosity of test substance was determined using ASTM D-445 method and was not carried under GLP. However, the methodology for viscosity determination is commonly used in the US lubricant industry and is considered scientifically sound and acceptable. The ASTM method is similar or equivalent to the OECD or EPA test methods.

Principles of method if other than guideline:

Summary of ASTM D-445 method: The time is measured for a fixed volume of liquid to flow under gravity through the capillary of a calibrated viscometer under a reproducible driving head and at a closely controlled and known temperature. The determined kinematic viscosity value is the product of the measured flow time and the calibration constant of the viscometer.

GLP compliance:

no

Remarks:

Test was compliant with ASTM method

Type of method:

capillary viscometer (static)
