OECD TG 124: Determination of the Volume Specific Surface Area (VSSA) of Manufactured Nanomaterials

 

Quantifying nano-scale characteristics to ensure regulatory compliance and material innovation.
 

The Volume Specific Surface Area (VSSA) is a pivotal parameter used to define and characterize nanomaterials. At Weshin Inspection Tech , we conduct high-precision VSSA determinations in strict accordance with OECD Test Guideline 124 (TG 124), providing essential data for the classification and safety assessment of manufactured nanomaterials.

 

The Critical Role of VSSA in Nanotechnology

 

VSSA measurement is a regulatory cornerstone for substances in the nano-range:

  • Regulatory Classification: Under the European Commission’s definition, a solid material with a VSSA greater than 60 m2/cm3 is generally classified as a nanomaterial.

  • Surface Reactivity Insights: High VSSA values correlate with increased surface energy and biological interaction potential, crucial for toxicology profiles.

  • Industrial Application Excellence: Ensuring the performance and stability of catalysts, pigments, and advanced functional powders.

Global Dossier Support: Meeting mandatory data requirements for REACH, EU Cosmetics Regulation, and national nanomaterial inventories
