This Technical Specification provides guidance on the preparation of specifications for the characteristics of manufactured nano-objects and their measurement methods. This is intended to help ensure the delivery of products with consistent properties for subsequent processing and/or final product performance. This Technical Specification includes guidance on specifying the physical and chemical characteristics of manufactured nano-objects, which might affect performance or subsequent processing. A list of applicable measurement methods is given in Annex B. This Technical Specification also does not include guidance on specifying materials containing nanosized phases formed in situ by a transformation in the material, e.g. Guinier-Preston zones in precipitation hardening metals. Furthermore, it does not specify quantitative requirements for the object to be considered a nano-object, but lists appropriate examples of characteristics and properties and their measurement methods useful for specifying nano-objects. Characteristics and measurement methods for nano devices are not included. Although this Technical Specification refers to parameters, which could be considered aspects of material quality, it is not intended to provide guidance on the establishment of quality management systems. For guidance on quality management systems, reference can be made to ISO 9000.
