Iran Introduces 12th Version of Int'l Nanotechnology Standard

Surfaces that are difficult to get wet with water are considered to be super-hydrophobic surface. They repel water droplets and do not get wet in contact with water. Various methods have been used to produce super-hydrophobic surfaces and coatings.

Due to their properties, super-hydrophobic surfaces and coatings have many applications in various industries such as automobile, construction, healthcare, optics, and electronics. The market for super-hydrophobic surfaces and coatings for 2020 was about $1.8 billion.

Super-hydrophobic surfaces and coatings are usually subjected to different working and environmental conditions. Unfortunately, despite the large market, there has not been standards for evaluating the durability of super-hydrophobic surfaces and coatings.

ISO/TS 10689:2023 standard aims to determine the performance evaluation methods of super-hydrophobic surfaces and coatings in different working and environmental and weather conditions. The evaluation criteria are the comparison of the advance angle, retreat angle, and contact angle lag of the samples before and after exposure to the aforementioned working and environmental conditions. Moreover, this document facilitates communication between interested parties.

So far, a total of 104 international standards have been published by the Technical Committee of ISO/TC229 Nano Technology Standards, of which 12 standards have been developed under the supervision of the Islamic Republic of Iran. Compilation of international standards usually takes two to three years. The basis of developing international standards in the International Organization for Standardization (ISO) is global consensus by the member countries.

The member countries of the technical committees provide various expert opinions for the completion and development of the standard at different stages of standard development. There are 39 countries as main members and 18 are observer members in the Technical Committee of ISO Nanotechnology Standards. With the publication of the above standard, Iran has developed the most Nano standards in the ISO organization after the United States, Japan, South Korea, and the United Kingdom.
