Characteristics and Measurement

Nanotechnology characteristics and measurement standards are published by ISO and IEC. Because many nanomaterials have different properties based on a variety of different factors, it is important to understand the properties of each in their different forms and chemical composition. The different chemistries include titanium dioxide, calcium carbonate, and more, and many of the listed documents cover different aspects of the materials in their powder forms.

ISO/TR 11360:2010

Nanotechnologies - Methodology for the classification and categorization of nanomaterials

ISO/TR 11360:2010 describes a classifying system, termed a nano-tree , upon whose basis wide ranges of nanomaterials can be categorized, including nano-objects, nanostructures and nanocomposites of various dimensionality of different physical, chemical, magnetic and biological properties.

IEC/TS 62622:2012

Artificial gratings used in nanotechnology - Description and measurement of dimensional quality parameters

IEC/TS 62622:2012(E), which is a technical specification, specifies the generic terminology for the global and local quality parameters of artificial gratings, interpreted in terms of deviations from nominal positions of grating features, and provides guidance on the categorization of measurement and evaluation methods for their determination. This specification is intended to facilitate communication among manufacturers, users and calibration laboratories dealing with the characterization of the dimensional quality parameters of artificial gratings used in nanotechnology. This specification supports quality assurance in the production and use of artificial gratings in different areas of application in nanotechnology. Whilst the definitions and described methods are universal to a large variety of different gratings, the focus is on one-dimensional (1D) and two-dimensional (2D) gratings.
