Qualifier:

equivalent or similar to guideline

Guideline:

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

GLP compliance:

yes

Other quality assurance:

other: DIN EN ISO 90001:2008, 14001:2005

Type of method:

capillary viscometer (static)

Temp.:

20°C

Parameter:

dynamic viscosity (in mPa s)

Value:

14.19

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

	Kinematic visosity		Density nD4^20	Dynamic Viscosity
	1. measurement	2. measurement
20 °C	17.19 mm²/s	17.14 mm²/s	0.8264 g/cm³	14.19 mPa s
40 °C	7.850 mm³/s	7.830 mm²/s

Conclusions:

Dynamic viscosity is 14.19 mPa s 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:

kinematic viscosities of 17.19 and 17.14 mm²/s at 20°C, corresponding to a dynamic viscosity of 14.19 mPa s.
