The standard was proposed by INIC’s Nanotechnology Standardization committee to the International Standardization Organization (ISO) four years ago. After considerable lengthy discussions and debates in these four years, the document has been finally approved and published and it is now available at www.iso.org (standard number: ISO/TS 21236-1:2019 ).

Reports indicate that clay nanomaterials are of particular importance in today's industry and technology all over the world. Clay nanomaterials could be used in various medical and pharmaceutical industries, packaging, paint and coating, automotive, rubber and polymer composites. This standard deals with the various characteristics of Clay nanomaterials including mechanical, thermal, physical, chemical etc. and their measurement methods, which can be referred to and used as a basic standard in international transactions.

This brings the number of Iranian developed international nanotechnology standards to five. Iran as well as China and Germany are currently ranked fourth based on the number of international standards.
