other: Comparable to guideline study with acceptable restrictions (e.g. non-GLP)
Qualifier:
equivalent or similar to
Guideline:
other: DIN 51562 ASTM D 445
GLP compliance:
no
Other quality assurance:
other: The laboratory complied with a quality management system according to DIN EN ISO 9001 : 2008 and DIN EN ISO 14001 : 2005
Type of method:
capillary viscometer (static)
Key result
Temp.:
20°C
Parameter:
dynamic viscosity (in mPa s)
Value:
131.83

The dynamic viscosity was calculated from the arithmetic mean of the kinematic viscosity (2 replicates) based on the density of the test item:

Kinematic viscosity Density nD4(20) Dynamic viscosity
1. measurement 2. measurement
20°C 131.37 mm²/s 131.38 mm²/s 1.0035 g/cm^(3) 131.83 mPa s
40°C 40.326 mm²/s 40.457 mm²/s

Kinematic viscosity at 40°C (arithmetic mean of 2 replicates): 40.39 mm^2/s

Conclusions:
Dynamic viscosity (ASTM D 445): 131.83 mPas at 20°C.
Executive summary:

Viscosity was determined using the capillary viscosimeter method (kinematic viscosity; ASTM D 445; mean of two determinations) at 20°C and 40°C: 20°C: 131.375 mm^2/s, corresponding to a dynamic viscosity of 131.83 mPa s.

Kinematic viscosity at 40°C (arithmetic mean of 2 replicates): 40.39 mm^2/s

Additional information

Viscosity was determined using the capillary viscosimeter method (kinematic viscosity; ASTM D 445; mean of two determinations) at 20°C and 40°C: 20°C: 131.375 mm^2/s, corresponding to a dynamic viscosity of 131.83 mPa s.

Kinematic viscosity at 40°C (arithmetic mean of 2 replicates): 40.39 mm^2/s

The laboratory complied with a quality management system according to DIN EN ISO 9001 : 2008 and DIN EN ISO 14001 : 2005

Based on the determined kinematic viscosity of the test item at 40°C (arithmetic mean of 2 replicates) of 40.39 mm^2/s, the substance is out of scope with regard to classification for aspiration toxicity according to REGULATION (EC) No 1272/2008 (CLP) or UN GHS.
