Standard Guide for Reporting the Physical and Chemical Characteristics of a Collection of Nano-Objects

SIGNIFICANCE AND USE
5.1 A nano-object is an individual, well-defined, and separable piece of a nanomaterial; in practice, nanomaterials used in research, products, testing, and other uses are almost always collections of nano-objects. Individual nano-objects and collections of nano-objects are the two major types of nanomaterials in use. The description of a collection of nano-objects is covered in this guide. The description of an individual nano-object is covered in Guide E3144. Nano-objects, individually or as a collection, are often embedded in other materials for commercial, research, and other uses. These embedded nanomaterials can be described using the information categories and descriptors included in these guides.  
5.2 Nanomaterials are of growing importance in research and commerce, and data on their physical and chemical characteristics are critical to predict performance, to transact commercial activities, to assess their potential for harm to human and animal health and the environment in general, and to support regulations that affect their use. A collection of nano-objects is the predominant type of nanomaterial tested and used in commerce.  
5.3 The four types of data and information used to describe a collection of nano-objects are: physical and chemical characteristics; production; specifications; and general identifiers (names and classifications), as shown in Fig. 1.

5.4 This guide deals solely with data and information to describe the physical and chemical characterization of a collection of individual nano-objects.

SCOPE
1.1 This guide provides guidelines for a description system to report the physical and chemical characteristics of collections of nano-objects. It establishes information categories and descriptors useful in describing collections of nano-objects uniquely and such that the equivalency of two or more collections of nano-objects can be determined according to specific criteria.  
1.2 This guide is designed to be directly applicable to reporting the physical and chemical characteristics of collections of nano-objects in most circumstances, including, but not limited to, reporting original research results in the archival literature, developing ontologies, database schemas, data repositories, and data reporting formats, specifying regulations, and enabling commercial activity.  
1.3 This guide is applicable to collections of naturally occurring, engineered, and manufactured nano-objects.  
1.4 One goal of the guide is to help ensure that when measurement results are reported, they are reported uniformly.  
1.5 A second goal of the guide is to encourage reports on the properties and functionalities of a collection of nano-objects to include as much detail as possible about the physical and chemical characteristics of that collection so it is uniquely specified.  
1.6 This guide does not cover the chemical reactions or reactivity of a collection of nano-objects.  
1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.9 This international standard was developed in accordance with internationally recognized principles on standardization establishe...
