Adequacy of study:
key study
Study period:
2012
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The study was done in accordance with EU guidance, but not conducted in accord with GLP compliance.
Qualifier:
equivalent or similar to
Guideline:
other: ASTM D445
Deviations:
not specified

no
Type of method:
capillary viscometer (static)
Temp.:
20°C

dynamic viscosity (in mPa s)
Value:
2.416
Temp.:
20°C
Parameter:
kinematic viscosity (in mm²/s)
Value:

Test 1

Dynamic viscosity = 2.4218 mPa/s

Kinematic viscosity = 1.0049 mm2/s

Test 2

Dynamic viscosity = 2.4095 mPa/s

Kinematic viscosity = 0.9998 mm2/s

The reported results are the average of the 2 tests.

Conclusions:
The viscosity of DIOFB is 2.4157 mPa/s (dynamic) and 1.0024 mm2/s (kinematic) at 20 °C.
Executive summary:

The viscosity of DIOFB was measured using a Cannon-Fenske Routine viscometer.

While no specific guideline was cited, Cannon-Fenske routine viscometers are approved based on ASTM D445, which is an approved method in the ECHA Chapter R.7a: Endpoint specific guidance. Total of six measurements were made in two separate tests at 20 °C. The reported results are the averages of the two tests. The study was not GLP compliant. Therefore, it is considered reliable with restrictions.
