This standard is the 8th international Iran-led standard in the field of nanotechnology that was published after three years of continuous efforts supported by Iran’s Nanotechnology Innovation Council (INIC).

This International Standard specifies measurement protocols and test conditions by which changes in the protein secondary structure during interaction with nanomaterials are determined using ultraviolet circular dichroism.

This standard was proposed to the International Standard Organization (ISO) in 2017 with the support of INIC. After approving Iran's proposal, various and extensive studies were conducted and several expert meetings were held with Iranian as well as foreign experts. The standard was finally published at the official website of the International Standard Organization (www.iso.org) in January, 2021.

A total number of 83 international standards have been published by ISO’s Technical Committee of Nanotechnology standards. Eight of them were published under Iran’s leadership.

Commonly, it takes 3-4 years to develop an international standard. This standard is approved after global consensus among member countries of ISO. Member countries of the technical committees express their various expert comments during different stages of standard development. There are 37 member countries as well as 18 observer countries in the ISO's Technical Committee on Nanotechnology.
