Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Test Guideline 114 (Viscosity of Liquids)
- Deviations:
- not specified
- Principles of method if other than guideline:
- The viscosity of the liquids is measured using a stress-controlled rotational rheometer (Paar-Physica UDS 200) fitted with a concentric cylinder system. Samples with low viscosities are measured with a double-gap (22.25/22.75; 23.5/24.0 mm) system whereas high viscosity liquids are measured with a single gap (12.5/13.56 mm) device. A few measurements are conducted over a shear rate range between 1 and 100 s-1. When the flow is Newtonian (i.e. the viscosity is independent of shear rate), which is usually the case for acrylate resins, the viscosity is returned at 20 or 100 s-1. The temperature is 23.0 °C and is controlled within 0.1°C.
