Nanotechnology and standardization
Nano products standard
Packaging of food and medical devices are standardized
National Standard To “Determination of specifications and measurement methods Nano Polystructures used in food packaging” And “Biological evaluation of medical devices” Compiled and ready for publication. Standard “Nanotechnology - Nanostructured polymeric films for food packaging with barrier properties - Determination of characteristics and measurement methods” and also the national standardNanotechnology - Biological evaluation Medical devices - Part 22: Guide to Nano Materials" were approved and ready to be published.
To compile this National Standards, from ISO international standard Nos. 21975 and 10993-22, which were issued in 2020 and 2017 by International Standard Organization (Iso) It has been published and used as a source.
Common plastics used in packaging include polyethylene, polypropylene, polyamide, and polyester, and the presence of nanoparticles in packaging can improve various characteristics of polymeric films. such as gas permeability, water vapor permeability, ultraviolet light permeability, thermal properties and mechanical strength should be effective..
Standard medical devices It is designed to provide a general framework and highlights important aspects that are necessary when Safety assessment Medical devices consisting of, containing and/or generating Nanomaterials be considered. Also, this standard identifies hidden bugs and common obstacles Nanomaterials test Compared to bulk substances or chemical species, it characterizes small molecules. In this standard, Technical knowledge available for nanomaterials are described and test protocols are described and presented in detail. Therefore, this new standard can serve as a basis for future standards including “Detailed protocols for testing nanomaterials” be.
Nano and product standardization and safety
Developing a national standard for performance evaluation and classification of hydrophobic surfaces
Standard "Nanotechnology - Coatings and Superhydrophobic Surfaces - Performance Evaluation and Classification Based on Measurement of Contact Angle by Baseless Drop Method - Characterization and Test Methods" has been approved and ready to be published. They are increasing in different industries. The approximate market of waterproof coatings in 2020 was about 1.8 billion dollars.. Various methods have been developed to make waterproof surfaces, such as: Chemical vapor deposition, spin coating, chemical etching, sputtering, plasma deposition, electrolytic plasma oxidation, anodizing, photolithography, cell-gel.
Knowledge base and standard
Some of the special properties of the hydrophobic surface are:: The property of self-cleaning, anti-dust, anti-bacterial, anti-freezing, corrosion resistance, low friction and compatibility with the body.. Hydrophobic surface used in the industry, they are exposed to different working conditions, and as a result, their hydrophobic properties gradually change or disappear.. These working conditions include mechanical wear, being exposed to sunlight, being in a corrosive chemical environment, and temperature cycling.. Therefore, the durability of the waterproof surface when faced with these conditions should be checked..
This standard Methods test To evaluate the performance of the surface and determines the water-repellent surface coatings.. In this Standard Test methods to measure the durability of this surface against different environmental conditions such as: Shear and normal stress, abrasion, soft impact (water)Hard blow (sand)Sunlight, liquids (Acid, base, ionic substances) And the temperature cycle is presented.
