OECD TG 109: Density of Liquids and Solids

Precision measurement and reliable data to power your regulatory compliance and R&D excellence.

Density is a fundamental physico-chemical property required for the characterization of chemical substances. At Weshin Test Technology , we provide high-accuracy density determination services strictly following the OECD Test Guideline 109 (TG 109).

The Importance of Density Determination

Whether for regulatory registration (such as REACH or biocides) or industrial quality control, accurate density data is indispensable. It plays a vital role in:

• Regulatory Submissions: Fulfilling mandatory data requirements for global chemical inventories.

• Environmental Modeling: Predicting the distribution and fate of chemicals in soil and water.

• Logistics & Safety: Determining storage requirements, packaging volumes, and safety protocols.
   

Our Testing Capabilities

We utilize state-of-the-art instrumentation to handle a wide range of material types, selecting the most appropriate method specified in OECD TG 109:

• For Liquids: Pycnometer method and the high-precision Oscillating U-tube method.

• For Solids: Gas comparison pycnometry and liquid displacement techniques for varying particle sizes.
