FR Recognition Number 18-14
Standard
ISO /TR 11360 First edition 2010-07-15
Nanotechnologies - Methodology for the classification and categorization of nanomaterials
Scope/Abstract
This Technical Report 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.

However, the classifying system presented in this Technical Report does not claim to provide full coverage of the whole range of nanomaterials.
Extent of Recognition
Partial recognition. The following part(s) of the standard is (are) not recognized:
Paragraph 2 in Section 2 Nano-tree structure
Rationale for Recognition
This standard is relevant to medical devices and is recognized on its scientific and technical merit and/or because it supports existing regulatory policies.

This standard is recognized in part because:
Paragraph 2 in Section 2 Nano-tree structure is in conflict with published final guidance. See Section"II Discussion A. Points to Consider" in the guidance listed below.
