The International Organization for Standardization (ISO), Technical Committee on Nanotechnologies (TC 229) has recently published a new standard in its Nanotechnologies series entitled "Measurement technique matrix for the characterization of nano-objects" (ISO/TR 18196:2016). The document provides a matrix intended to guide users to commercially available techniques relevant to the measurements of common physico-chemical parameters for nano-objects.

The document connects the nanoobjects' parameters most commonly needed to be measured with corresponding measurement techniques. According to ISO, the standard should be a useful tool for nanotechnology interested parties to rapidly identify relevant information for measuring nano-objects. However, many of the listed techniques have not been validated through round-robin testing or any other means for the measurement of nanoobjects. Therefore, it should be regarded as a starting point and resource to help identify potentially useful and relevant techniques; it is not an exhaustive or primary source.

ISO recommends that once a technique has been identified, the reader refer to relevant international standards and conduct a literature search for similar or comparable applications. Other potential sources of information include instrument manufacturer's applications notes and technical literature

ISO/TR 18196:2016: "Nanotechnologies - Measurement technique matrix for the characterization of nano-object"

• ISO/TR 18196:2016 provides a matrix that guides users to commercially available techniques relevant to the measurements of common physiochemical parameters for nano-objects. Some techniques are also applicable to nanostructured materials
