OECD TG 114: Viscosity of Liquids

 

Precise fluid characterization to drive industrial efficiency and regulatory compliance.
 

Viscosity is a fundamental physical property that dictates how a liquid flows, settles, and disperses. At Weshin Inspection Tech , we provide comprehensive viscosity determination services in strict accordance with OECD Test Guideline 114 (TG 114), catering to a wide array of chemical and industrial substances.

The Importance of Viscosity Determination

 

Accurate viscosity data is a prerequisite for both product safety classification and engineering excellence. It is essential for:

  • Hazard Classification: Identifying potential aspiration hazards as required by GHS and REACH regulations.

  • Performance Optimization: Ensuring the correct consistency for coatings, lubricants, and agricultural formulations (e.g., sprayability).

  • Environmental Modeling: Predicting the spread and penetration rates of chemical spills in aquatic or terrestrial environments.
     

Our Testing Capabilities

 

Weshin Inspection Tech utilizes a suite of standardized methods to characterize both Newtonian and non-Newtonian fluids:

  • Rotational Viscometry: Versatile measurement for complex fluids, allowing for the analysis of shear-dependent behavior.

  • Capillary Viscometry: The gold standard for high-precision kinematic viscosity measurements of low-viscosity liquids.

  • Falling Ball Method: Reliable analysis for transparent Newtonian liquids following the principle of terminal velocity.
     

Why Partner with Weshin Inspection Tech?

 

  • Strict Temperature Regulation: We conduct measurements at standardized temperatures such as 20°C and 40°C using high-stability thermal baths to ensure reproducibility.

  • Comprehensive Data Profiles: We report both dynamic viscosity ($mPa \cdot s$) and kinematic viscosity ($mm^2/s$), providing a complete picture of your product's flow properties.

  • Regulatory-Ready Documentation: Our test reports are structured to meet the stringent requirements of international chemical authorities and quality management systems.
